DetailsAutomatic trouble-proof brake apparatus with double pawls is safe and reliable.
Durable friction discs
The lifting chains are equipped with guide wheels, which can effectively prevent the chain from derailing.
All the gears and shafts have been treated by special heat treatment to ensure excellent strength performance.
After the quenching and tempering treatment, the hooks and chains will have higher hardness.
The upper and lower pulley hooks have been forged to make them more secure. Besides, the hooks are equipped with safety devices, which make the loaded objects hard to fall off.
The surface of the chains is treated with a powder spray treatment, so that they will have better corrosion resistant performance.
