Caterpillar Hall-off Unit
Product Introduction
For different pipe diameter and extruder speed requirements, we designed all kinds of the Hall-off unit, have two caterpillars, three caterpillars, four caterpillars, six caterpillars until upto 16 caterpillars. The wide adjustable range for the Hall-off unit, running is stable and reliable, and small noise.
Each caterpillars by a separate asynchronous or servo motor drive, Via digital controller keep the accuracy of the caterpillar speed synchronization. The large capacity compression air cylinder, contact length is overlength between the pipe and the cat erpillar, can ensure a high friction tractive force. based on the switchable control for the 1/2 caterpillar, can switch to each other between the big pipe diameter and small pipe diameter, large scope of working for the Hall-off unit.
