Parameters

Winch mast system consists of mast, guying rope device and accessories etc.. And it is suitable for using on field ground.

This series of products is a new generation of products which is mainly developed to meet the requirements of light load and moving fast. The main characteristics are light in weight, easy to carry, winch power, fast speed of raising and falling. But because of considering the light load, this series of products need guying rope in the work. Can work without guying rope when the wind speed is 6 grade. Must work with guying rope when the wind speed is more than 6 grade.

Drived by a manual winch which has high transmission efficiency. And can raise or lower steadily，has no impact vibration.

The ratchet check mechanism is safe and reliable. And has safe self-locking function at any position. The mast is always in the self-locking state. The crank does not automatically reverse to bring damage.

All transmission parts are all arranged in the mast body or in the winch, no exposed parts. Protective performance is good.
