Features：

1、Even at a low coefficient of friction between the pipe and the belt/rubber blocks, the cylinder with large size can still guarantee a very high traction.

2、 The lower caterpillars can be set mechanically/electrically to the pipe, and the upper caterpillars/rubber blocks are pressed onto the pipe pneumatically.

3、Each caterpillar driven by a separate induction motor. Achieving synchronization control through the digital controller, can ensure that all caterpillars are precisely synchronized speed.

4、The haul-off with three caterpillars and above is equipped with the imported LENZE motor. The haul-off with two caterpillars is equipped with NORD motor.

5、The imported encoder ensures that the speed will feedback to motor correctly and stably.
