Five tons Dual-bullwheel powered motorised winch

Introduction:

In line stringing installation, normally steel wire rope which is in very high cost is applied for pulling and craning heavy objects. Most capstan with small diameter which is widely used can easily damage the rope. By using two bullwheels with line grooves to increase the circle radius and avoid ropes to be against each other, this new designed winch makes the operation safety and reliable.

This dual bullwheel winch is powerful with high linepull speed, can be used in tower erection and overhead line stringing. Contains a independent braking system. With tyers can be easily moved.
