1. Two-stage transmission structure, for the largest gear ratio, to ensure the smallest structural appearance. Save time and effort, small relative volume and light weight.
2. Horizontal traction or pulling brake structure can be in self-locking state at any time. Ensure reliable brake braking. Forward rotation to collect the rope and reverse release the rope, without manually going to move the ratchet mechanism, can be achieved.
3. Both sides can be hand shaken, both a person left or right shaking, in the case of necessity, but also two people together shaking .
4. Large capacity rope tube design, the longest capacity of 100 meters.
