We manufacture pulling devices for various standard sizes of produced pipes. Two-, four-, six-, eight-, ten- and twelve-track haul-off devices can be used depending on the pipe and line speed.
The tractors are equipped with either one common motor, or each track is supplied with an independent motor.
For high speed small diameter pipe production lines, belt pulling devices are available.
For profile lines there are combined pulling / cutting devices.
For large diameter pipe production lines, the tracks have spring compensators, as well as automatic adjustment of the distance between the tracks, in order to avoid “jamming” the device when starting the line, when the starting pipe may have a larger diameter.
For larger pipes, a winch can be fitted to reduce waste.

Different dimension, speed of production requirements, configuration of multi-caterpillar, large speed ratio hauling mechanism can be selected.
The whole series of haul-off unit adopt the scheme of "one pull more" independent permanent magnet synchronous servo motor for each caterpillar, which can ensure a stable large speed range of more than 50 times.
Liansu Haul-off unit can simultaneously meet the requirements of fast hauling of small-sized pipe and slow hauling of large-size thick wall pipe, with stable speed and strict synchronization of each caterpillar.
