Lever hoist lifting traction performance
lever hoist in the structure of a dual pawl design, greatly improving the safety and reliability. In lifting and lowering, the handle can be repeated operations easier. Work led brake clutch, pull the load when the chain is free, easy to adjust the position of the next hook.
lever hoist is the most common type of domestic HSH series, can withstand the rated load ranges between 750kg-9t main advantages are: a safe, reliable, and easy maintenance. Two, flexible operation, durable. Three, high mechanical efficiency, pulling force is small. Four, small size, light weight, easy to carry.
By pulling the handle lever hoist heavy lifting, no power, so much for lifting height lower, lighter objects, while multi-angle traction, a wider operating range.
