Belt and Caterpillar Haul-offs

Belt Haul-offs

Belt haul-offs are used for continuous extraction of pipes and profiles. They are known for especially consistent performance even at high production speeds. The belts are driven by brushless AC servo drives. Both belt carriers can be mechanically or pneumatically adjusted in height. The belts can also be supplied with a cellular vulcanised or rubber layer.

 

Caterpillar Haul-offs

Depending on the pad type, dual caterpillar haul-offs can be used for pipes or profiles. Multiple caterpillar haul-offs are used for pipe haul-off. The lower caterpillar carriers are adjusted manually, the upper caterpillar carriers are suspended and are pneumatically adjusted.
