Start With Your Pulling Requirements
Choosing a haul-off starts with your pipe and your production conditions, not with the number of caterpillars on the frame.
Pipe diameter, wall thickness, production speed and line resistance decide the traction it takes to keep your pipe moving steadily. The same details decide how much contact area and clamping force you need before slip, surface marks or deformation start showing up on the product.
Pipe Material
PVC, HDPE, PE, PPR and other materials behave differently under the pads. Each one needs its own traction and contact conditions to hold without damaging the surface.
Pipe OD Range
Your smallest and largest diameter set the opening range, the contact area and the machine configuration. A wide range on one machine is possible, but it has to be designed in from the start.
Wall Thickness And SDR
Thin wall pipe collapses under pressure that heavy wall pipe barely notices. Your SDR range tells us how much clamping force, support and pulling force the machine can safely apply.
Line Speed
What matters is stable traction across the full speed band you actually run, slow start up included, not a maximum figure printed on a spec sheet.
Pipe Weight And Line Resistance
Pipe weight, cooling length and the drag built up through the tanks all pull against the haul-off. The longer and heavier the line, the more traction it has to hold in reserve.
Existing Line Or New Line
On a replacement, center height, footprint, speed range, voltage and the downstream interfaces have to match what is already bolted to your floor. Send photos and the old nameplate and we work from those.
From Production Data To Haul-Off Configuration
Every configuration we quote runs through the same four steps, in this order. Your data goes in at the top, the machine layout falls out at the bottom.
Pipe Requirements
Material, OD range, wall thickness, speed band and line length.
Required Traction And Speed Range
Pulling force at your slowest and fastest running speed, with reserve for line drag.
Contact Area And Clamping Method
How much pad surface holds the pipe, and how the pressure is applied and held.
Belt Or Caterpillar Configuration
The number of tracks, their length and the frame that carries them.
Do Not Choose A Haul-Off By Caterpillar Count Alone
A bigger machine is not automatically a better match for your line. The right configuration gives you enough traction at your required speed while applying only the pressure it takes to keep the pipe moving steadily. Anything beyond that is pressure your pipe surface pays for.
Configurations For Different Pulling Requirements
Different pipe sizes and production conditions need different contact areas, traction levels and machine structures. Use this as a starting point when you compare configurations, then send your specs so we can confirm which one fits your line.
| Configuration | Typical Application | Why It Is Used | Check Before Selection |
|---|---|---|---|
| Belt Haul-Off | Small diameter and high speed pipe production | Continuous belt contact keeps pulling stable at higher line speeds | Pipe diameter, speed, surface condition, required grip |
| 2 Caterpillar | Standard small and medium pipe production | Simple structure with enough contact for most conventional extrusion lines | Pipe weight, wall thickness, line speed, required traction |
| 3 And 4 Caterpillar | Lines that need more contact and more pipe support | Extra contact spreads traction around the pipe so you stop relying on high clamping pressure | Pipe diameter, deformation risk, traction, contact length |
| 6 And 8 Caterpillar | Large diameter and heavier pipe production | Greater contact area delivers higher traction while holding the pipe from several directions | Pipe weight, wall thickness, production speed, required pulling force |
| Multi Caterpillar | Large or special pipe with demanding traction requirements | Independently controlled contact points give higher traction and more even support | Pipe geometry, load, synchronization, center height, line layout |

Caterpillar Count Is Only One Part Of The Selection
More caterpillars do give you more contact area and more available traction. They also add mechanical complexity, more wear parts and more cost, so the count on its own tells you very little about whether a machine fits your line.
The right configuration covers the traction your line actually needs while keeping clamping pressure, pipe deformation and day to day operating complexity under control.
Send These Four And We Can Narrow It Down
Stable Pulling Starts With Stable Haul-Off Speed
A haul-off should do more than reach the maximum speed on the datasheet. It has to hold a steady pulling speed while pipe weight, line resistance and production conditions keep shifting under it. On a multi-caterpillar machine, every caterpillar also has to run at the same effective speed so your pipe is pulled evenly through the line.
Do Not Compare Maximum Speed Alone
A machine rated for a higher maximum speed is not automatically a better fit for your line. That number is measured with nothing in the tracks, and your line never runs that way.
Ask instead how the haul-off holds your required speed under load, how multiple caterpillars stay synchronized across the working range, and how its speed control connects to the extruder and cutter you already run.
Grip The Pipe Without Damaging It
Your haul-off needs enough grip to move the pipe without slip, but turning up the clamping pressure is not always the fix. Too much pressure marks the surface or deforms thin wall, hot or softer pipe. Stable pulling comes from the balance between contact area, pad design and clamping pressure.
Find The Right Grip
Pipe Slipping
Not enough contact or clamping force lets the pipe slide against the pads. Pulling turns unstable, length control drifts and the pads wear out faster than they should.
Stable Pulling
Enough contact area with controlled pressure keeps the pipe moving steadily. The load is spread across the pads instead of being squeezed into the pipe wall.
Marks Or Deformation
Excess pressure leaves traction marks, flattens thin wall pipe and pushes roundness out of tolerance while the material is still warm and willing to move.
Four Things Decide How Your Pipe Is Held
Change any one of these and the pressure you need changes with it. That is why grip gets designed around your pipe, not dialed in at the plant on the day something starts slipping.
Contact Length
Longer contact between pipe and pads buys you more traction without leaning on higher clamping pressure. On heavy or fast lines this is usually the cheapest way to add pulling force.
Pad Width And Contact Area
The pad has to spread the pulling load across real surface. Concentrate the same force onto a narrow strip and the pipe carries all of it in one place, which is where marks start.
Rubber Pad Profile
Compound and surface profile have to give you friction without printing themselves onto the finished pipe. Softer is not always safer, and harder is not always more grip.
Clamping Pressure
Pressure has to be adjustable across your pipe sizes, wall thicknesses and materials. The target is enough pressure to stop slip, not the highest number the machine can reach.
Tell us the pipe you run and we will come back with contact length, pad specification and the working pressure range that suits it.
More Pressure Is Not Always More Traction
When a pipe starts slipping, turning up the pneumatic pressure should not be the first and only move your operator makes. Past a certain point you stop adding traction and start adding damage. Work through these before the regulator gets touched.
Pad wear and remaining profile
Contact length actually in use
Pipe temperature reaching the haul-off
Alignment with the line center
Pulling force the line really needs
Is The Haul-Off Causing These Problems?
When pipe quality or line stability changes, the haul-off is one of the systems worth checking. Not every problem starts here. Work through the symptoms below to see where traction, clamping, synchronization or alignment may need attention.
Pick Your Symptom
Check The Complete Line Before Replacing The Machine
Similar symptoms come from upstream and downstream conditions just as often as they come from the haul-off itself. Run through these together with your haul-off settings before you change the configuration. It is a short exercise, and it saves you buying a machine that was never the problem.
Review These First
Extrusion output and cooling condition
Pipe temperature at the haul-off
Line alignment through the tanks
Cutter resistance behind the machine
Actual production speed, not the set point
Replace Or Upgrade Without Rebuilding The Whole Line
If your current haul-off is holding production back, replacing the complete extrusion line is rarely the answer. What a replacement has to prove is that the new machine covers your pulling requirements while matching the mechanical and control interfaces already on your floor.
When An Upgrade Is Worth Reviewing
Production Speed Has Increased
Your haul-off may have run reliably at the original line speed and then started slipping or losing stability once you pushed the output up. The machine did not change, the demand on it did.
What matters in the new configuration is traction at the speed you actually run now, not a higher motor rating on the datasheet.
The Current Machine Is Causing Downtime
Worn pads, stretched chains, adjustment that fights you, slow diameter changes and drive components nobody stocks anymore all turn a productive line into a difficult one.
At some point replacing the haul-off costs you less than repairing the same machine every few months. Send us what breaks and how often, and we can tell you where that point sits.
You Need A Larger Pipe Range
Moving up in diameter or wall thickness adds pipe weight, and pipe weight adds required traction. The machine that handled your old range may simply not have the contact area for the new one.
That usually points to more contact area, a different caterpillar arrangement or a wider opening range, all while keeping the center height your line already runs at.
Pulling Is No Longer Stable
Slipping, uneven pulling between caterpillars, or an operator who has to keep raising clamping pressure to get through a shift all say the same thing. The configuration no longer matches your production conditions.
Find the cause first. Adjustment, refurbishment and replacement are three different answers, and only one of them is worth spending on.
Send These And We Work From Your Existing Line
For a replacement we quote against what is already bolted to your floor, so the new machine drops into the same position without moving the rest of the line. Photos of the current haul-off and its nameplate cover most of it.

Missing Half The List? Send It Anyway
Photos of the machine and its nameplate answer most of it. Whatever is still open, Maggie will ask you for it directly instead of guessing.
From Existing Line Data To Replacement Configuration
Five steps, in this order. Nothing gets built until the last one is signed off by you.
Existing Line Information
Machine photos, nameplate, pipe range, speed and the space you have.
Traction And Interface Review
What the line needs to pull, and what the new machine has to bolt into.
Haul-Off Configuration
Track count, contact length, pad specification, drive and control method.
Layout And Connection Check
Center height, footprint, pipe direction and the signals either side of it.
Approval Before Manufacturing
Drawings and specification confirmed by you before anything is cut.
Confirm The Interface Before You Replace The Machine
A replacement haul-off cannot be chosen on pipe size and pulling force alone. Those two numbers tell you the machine can do the work. They tell you nothing about whether it fits the line you already run. Lock these down before manufacturing starts and the new machine drops in with the minimum modification on your side.
Reduce Downtime When Pipe Sizes Change
Changing diameter is more than opening or closing the caterpillars. The haul-off has to come back to the correct centerline, contact position and clamping condition for the next product before you restart.
Four steps your operator works through on every size change. Plan them and you stop paying for trial and error after the line is already running.
Caterpillar Positioning
The caterpillars move to match the new diameter while keeping contact even all the way around the pipe. Depending on the configuration you specify, that positioning is manual, motorized or automatically controlled.
Tell us: How often you change size, and who does it
Maintain The Pipe Centerline
After the diameter changes, the pipe still has to line up with the cooling equipment ahead of it and the cutter behind it. Center height consistency matters most when the machine sits inside a line that was built around it.
Tell us: Your line center height and pipe range
Reset Clamping Pressure
Different diameters, wall thicknesses and materials want different clamping settings. Reusing yesterday's pressure is how thin wall pipe gets flattened, or how a heavier pipe starts slipping ten minutes into the run.
Tell us: Every material and SDR you run on this line
Confirm Contact Before Restart
Before you go back up to production speed, check that every caterpillar touches the pipe evenly and that the pipe travels through the machine without visible distortion or drifting off center. Two minutes here saves a shift of scrap.
Tell us: Your current changeover time, if you track it
A Diameter Change Should Be Repeatable
A good changeover puts your operator back on a proven position and a known pressure range. It should not send them hunting for the correct settings from scratch every time the size list moves.
When you compare haul-off machines, ask what actually has to be adjusted during a diameter change, and how those settings get repeated on the next run of the same pipe. The answer tells you more about your real downtime than any speed rating on the datasheet.
Make Daily Haul-Off Operation Easier To Control
Once the machine is correctly configured, your shift should turn on a small number of settings, the ones that actually move pulling stability and pipe quality.
Your operators should be able to adjust speed and clamping without reaching for tools every time production conditions shift.
Stable Production Should Not Depend On Constant Adjustment
Once the correct speed, position and pressure are established, the haul-off should hold them. A machine that needs your operator to keep correcting it is not a machine that has been set up well.
Repeated pressure or position changes inside the same production run are a reason to check machine condition, pipe condition and line alignment. They are not a reason to keep adjusting the settings.
Wear Parts That Directly Affect Haul-Off Performance
Some parts wear down quietly through normal production, and their condition shows up in your grip, pulling stability, alignment and downtime. The ones in continuous contact with the pipe, or carrying the pulling load, are worth inspecting on a schedule rather than after something goes wrong.
Rubber Haul-Off Pads
Pads decide friction, contact and what your pipe surface looks like coming out. Watch for hardened rubber, uneven wear, damaged profiles, contamination or grip that has quietly dropped off. Worn pads slip even when nobody touched the clamping pressure.
Caterpillar Chains
Chain wear or tension that has drifted breaks up smooth movement and loads your caterpillars unevenly. Check tension, elongation, lubrication and anything that moves differently under load than it did last month.
Bearings And Rollers
Worn bearings and support components add resistance, vibration and misalignment to a machine that was running fine. Noise, heat or movement that feels wrong should get looked at before it starts damaging what sits next to it.
Pneumatic Components
On most configurations, cylinders, valves, regulators and air lines are what actually hold your pipe. Pressure that will not stay put, or a leak nobody has traced yet, turns into inconsistent contact and marks you cannot explain.
Drive Components
Motors, gearboxes and drives should run smoothly across your whole speed range. A change in noise, temperature, response or synchronization is the machine telling you something early. It is worth listening to before it becomes a stoppage.
Wear Part Package
Pads, chains, bearings and pneumatic parts sitting in your store are the difference between a two hour job and a two week wait. Tell us your machine and how many hours a week it runs, and we put a package together against that.
Keep The Haul-Off Running Consistently
Maintenance here comes down to the parts that move traction, synchronization, alignment and clamping stability. A small shift in pad condition, chain tension or air pressure will not stop your line today. Left alone for a few weeks, it becomes the reason your pipe is out of spec.
Six Checks Worth Scheduling
Check Pad Condition
Look for wear, damage, contamination and contact that is no longer even. Uneven pad wear is often telling you about alignment, uneven clamping or a difference between caterpillars, not about the pads themselves.
Check Chain Tension
Correct tension keeps caterpillar movement smooth. Chains that hang loose, or that are tensioned differently from each other, add vibration, add wear and take the consistency out of your pulling.
Check Caterpillar Alignment
Confirm the caterpillars are still where they should be and that the pipe runs through the machine center without side loading it never needed. Check this again after any mechanical adjustment or part replacement.
Check The Pneumatic System
Go through operating pressure, air leakage, cylinders, valves and regulators. The clamping system should give you stable, repeatable pressure. If it needs correcting during a run, something in that circuit is asking for attention.
Check Drives And Gearboxes
Watch for noise, vibration, temperature or drive response that has changed. On a multi-caterpillar machine, any difference in behavior between drives is worth investigating before it turns into uneven pulling.
Keep Adjustment Points Accessible
Anything that needs regular inspection, tensioning or replacement has to be reachable without pulling the machine apart. If a check takes an hour of disassembly, it stops getting done.
Maintenance Should Prevent Production Problems
Do not wait until the pipe starts slipping or the machine pulls unevenly before anyone looks at the haul-off. By the time a symptom reaches your product, the correction is bigger, slower and more expensive than it needed to be. Catch these while they are still small and the fix is usually an adjustment, not a shutdown.
Built And Assembled For Stable Haul-Off Performance
Frame fabrication, caterpillar assembly, rubber pad installation, drive integration, alignment and final testing. Every machine is built around the configuration you approved, with the work focused on mechanical alignment, consistent caterpillar movement and components installed the way they have to stay for years of production.
Want to see your machine at a specific stage? We send build photos and short videos during production, and you are welcome to inspect the machine yourself before it is packed.
What We Actually Check Before It Ships
Every machine runs before it leaves the workshop. These are the six checks that go into the report you receive, with photos and video from the run so you can see the machine working before it is packed.
Speed Test
We run the full operating speed range and confirm the machine moves smoothly at every setting, not only at the top and bottom of the band. Slow running matters as much as fast, because that is where your line starts and stops.
Caterpillar Synchronization
On multi-caterpillar machines we check that the tracks run together with no visible speed difference or uneven movement. A mismatch here is what shows up months later as uneven pad wear on your line.
Clamping System
Opening, closing and pressure adjustment are tested through repeated cycles. What we are confirming is that the clamping action is stable and repeatable, so the same setting gives your operator the same grip tomorrow.
Caterpillar Alignment
Position, parallelism and pipe centerline are verified against the drawing you approved. Getting this right in the workshop is what keeps contact even once the machine is in your line and running product.
Drive And Mechanical Check
Motors, gearboxes, chains, bearings and every moving component are checked for abnormal noise, vibration or movement while the machine runs. Anything that sounds wrong in the workshop gets fixed in the workshop.
Electrical And Safety Check
Control system, emergency stop, drives, interlocks and any electrical function agreed in your order are all tested before packing, at the voltage and standard configured for your market.
You See The Test Before You Approve The Shipment
Photos and video from the run go to you with the inspection report, and you are welcome to inspect the machine in person or send a third party agent instead. Nothing ships until you are satisfied with what the test showed.
What Comes With The Machine
Agree What Has Been Verified Before It Ships
Acceptance is not another set of workshop photos. It is the short list you and we sign off on, so there is no argument later about what was confirmed and what was assumed.
Six points. Confirmed in writing, with your drawing and order as the reference.
Machine Specification
Confirm the caterpillar configuration, speed range, overall dimensions and major components against what was agreed in your order. Brand and model of the bought-in parts included.
Mechanical Interface
Machine length, width, pipe center height and installation position checked against the approved layout. This is the one that decides whether the machine drops into your line or needs work on your floor.
Operating Functions
Caterpillar movement, speed adjustment, clamping control and every function specified for your machine, each one demonstrated rather than described.
Control Interface
Voltage, control signals and communication requirements confirmed as agreed for integration with the rest of your extrusion line. Signal type and terminal marking included, not just the voltage.
Safety Functions
Emergency stop, guards, interlocks and any other safety function agreed for your market, verified in operation before the machine is packed.
Test Condition
Record how the machine was tested. Empty, under simulated load, or pulling actual pipe. These are three different statements and they carry three different levels of proof, so the report says which one applies to your machine.
Ask any supplier for this in writing. A machine that only ran empty has not been tested against your production conditions, and you should know that before it leaves the workshop, not after it reaches your floor.
Frequently Asked Questions About Haul-Off Machines
The questions buyers actually send us before ordering. If yours is not here, send it to Maggie and you get a straight answer, not a brochure.
How do I choose between a belt and caterpillar haul-off?
It comes down to pipe size, production speed, required traction and how much contact your pipe needs.
Belt haul-offs are usually considered for smaller diameters and higher speeds, where continuous belt contact suits the product. Caterpillar machines give you more configuration flexibility when you need higher traction, larger pipe or additional support around the pipe.
Pick from your actual production conditions, not from the machine type.
How much pulling force does my haul-off need?
Required pulling force comes from the resistance the machine has to overcome in real production. Pipe weight, wall thickness, line speed, cooling section resistance, downstream equipment and every other source of friction along the line all feed into it.
A higher rating is not automatically better. What you want is enough traction across your whole speed range while contact with the pipe stays stable and controlled.
Can excessive clamping pressure deform the pipe?
Yes, and it shows up fastest on thin wall, warm or relatively soft pipe. Too much pressure moves roundness, leaves surface marks or compresses the pipe locally.
The goal was never the highest pressure the machine can produce. Grip comes from the combination of contact area, pad design and controlled clamping pressure working together.
Should I choose a servo drive or an inverter-controlled haul-off?
Neither one is automatically right. An inverter controlled AC drive suits many conventional extrusion lines perfectly well. Servo systems are worth considering where you need tighter speed control, faster dynamic response or more demanding synchronization.
Decide from required speed accuracy, operating range, synchronization requirements, production conditions and control architecture. Not from servo being the more expensive option on the list.
What should be verified during the pre-shipment test?
The scope should match your agreed configuration. Typically that covers operating speed range, caterpillar synchronization, clamping movement and pressure adjustment, caterpillar alignment, chain and drive operation, motor and gearbox operation, electrical controls, emergency stop and agreed safety functions, machine dimensions, pipe center height and the control interfaces you specified.
Just as important is the test condition itself. A no-load running test proves the mechanical and control functions work. It does not on its own prove pulling performance with your pipe. Where production line testing is available, actual pulling, slipping, surface condition and speed stability can be reviewed under agreed conditions.
How many caterpillars does my pipe extrusion line need?
There is no rule that assigns a caterpillar count to a pipe diameter. The configuration comes from pipe OD, wall thickness, material, pipe weight, line speed, required traction and deformation risk.
More caterpillars add contact area and spread the pulling load more evenly. They also add mechanical and control complexity, more wear parts and more cost. The right configuration gives you enough traction without unnecessary clamping pressure and without oversizing the machine.
What causes a pipe to slip in the haul-off?
Several conditions cause it, usually more than one at a time.
- Not enough contact area
- Incorrect clamping pressure
- Worn or contaminated rubber pads
- Not enough available traction
- Pipe surface condition
- Higher production speed or pipe weight
- Mechanical or alignment problems
Turning up the pneumatic pressure may quiet the symptom for a while. It should not be your first or only correction. Check pad condition, contact, alignment and the actual pulling demand alongside it.
Can a new haul-off replace my existing machine without changing the whole line?
In most cases yes, but the interface has to be reviewed before the replacement is finalized. What we need from you:
- Pipe center height and available installation space
- Pipe travel direction and current line speed
- Pipe range and existing haul-off dimensions
- Electrical supply and control signals
- Cooling section position and cutter interface
The layout and interface review happens before manufacturing, so you avoid unnecessary modification to a line that already works.
How often should haul-off rubber pads be replaced?
There is no reliable fixed interval. Pad life moves with pipe material, production speed, clamping pressure, pad compound, operating hours, surface contamination and alignment. Replace on condition, and watch for these signs:
- Grip dropping off
- Hardened rubber or cracking
- Uneven wear or damaged profiles
- Surface contamination
- Needing more clamping pressure than before
If slipping is getting gradually worse, check pad condition before you raise the pressure.
What information should I provide for haul-off selection?
Start with whatever defines the actual pulling requirement:
- Pipe material, minimum and maximum OD
- Wall thickness or SDR
- Minimum and maximum line speed
- Extruder output, if you have it
- New line or replacement project
- Existing haul-off configuration and current problems
- Pipe center height and any line drawings you have
You do not need to know the required pulling force or the caterpillar configuration before you contact us. Those come out of the review once we know your production and line conditions.
