When is a caterpillar puller the right choice?

For thin-walled hollow profiles with low stiffness during cure, cosmetic surfaces that must not carry clamp marks, and small sections pulled several at a time. Heavy, thick profiles needing high pull force are better on a hydraulic machine.

Can it pull several profiles at once?

Yes. With a multi-cavity die and the 300 mm track width of the ZS-L10A, several small profiles can be pulled in parallel. The cavity count is set during die design.

How long do the tracks last?

Track pad life depends on profile abrasiveness, clamping pressure and running hours. The factory has not published a figure; a spare-track price is included on the quotation.

What pull speed can I expect?

Speed is limited by resin cure in the die, not by the puller. Expected speed is stated for your profile after die design, not as a machine maximum.

Caterpillar pultrusion machine

A caterpillar pultrusion machine pulls the cured profile between two continuous, synchronized tracks instead of reciprocating clamps. Grip is spread over a long contact zone, so there is no clamp handover and no clamp mark. The ZS-L5A and ZS-L10A deliver 50 kN and 100 kN pull force with 2,500 mm and 3,000 mm holding zones.
