Multi-Caterpillars Haul-off Unit

The multi-caterpillars haul-off unit is an essential, high-performance component in modern plastic extrusion lines. Specially engineered for the continuous and stable pulling of large-diameter pipes, heavy-duty profiles, and sensitive tubes, this machinery ensures uniform tension without causing deformation.

Whether you are extruding PVC, HDPE, PP, or large industrial conduits, our multi-caterpillar haul-off machine delivers the precise pulling force required to maintain strict dimensional tolerances.

Multi-Caterpillars Haul-off Unit Features:

• Multi-Track Synchronization for Uniform Pressure

Equipped with multiple independent caterpillar tracks (ranging from 3, 4, 6, 8, to 12 tracks depending on your production needs), this unit distributes clamping pressure evenly around the perimeter of the pipe. This multi-caterpillar design prevents the ovality and crushing common in standard two-belt haul-offs when handling large or thin-walled pipes.

• Advanced Servo Drive System

Each caterpillar is powered by an individual AC servo motor or high-efficiency geared motor, ensuring perfect speed synchronization.

• Quick-Change & Wear-Resistant Rubber Blocks

Features high-friction, wear-resistant rubber pads shaped specifically to fit different pipe diameters.

Designed with a quick-click or easy-bolt mechanism, allowing operators to change blocks rapidly during product changeovers, minimizing downtime.

• Pneumatic Clamping & Flexible Adjustment

The clamping mechanism utilizes independent pneumatic cylinders for each track. This allows for individual pressure adjustment, ensuring the perfect balance between high pulling grip and surface protection for delicate profiles.
