Another main factor to judge the quality of hand lever hoist is hook: the hook and safety plate of high quality hand lever hoist are made of high quality materials and precision forging technology with high strength and durability.Inferior hand lever gourd no matter choose material, craft and service life to want difference a lot of.
The handle design of high quality hand lever hoist is reasonable, the hand lever force is small, the operation is comfortable and convenient; Hand lever hoist handwheel design is reasonable, with brake clutch device, can freely pull the chain in no load, quickly and easily adjust the lower hook position, greatly convenient operation; Hand lever hoist chain made of high quality alloy steel, professional lifting chain integrated molding, overload not broken, just deformation, great guarantee safety; Inferior hand pulls gourd chain material to be qualitative difference, firm and durable intensity also is unsatisfactory, use welding processing between chainlink even, use time is long, extremely easy fracture, produce dangerous accident.
