What use lever hoist safety requirements

What use Hoist equipment safety requirements when
Lever hoist is a lightweight and easy manual traction machinery. It has a compact structure, small size, light weight, portable, stable performance characteristics. Its working

principle is smoothed by the two pairs of self-locking clamp, like two steel fixing a new alternating rope clip for linear reciprocating motion, from  To achieve traction operation, it can serve in a variety of projects traction winch. Lifting and other operations. In addition to the horizontal and vertical use, it is also in the slopes, rugged, narrow alleyways, winding turns working conditions to operate, can be anywhere and have no electricity  The source environment. Lever hoist used for loading and unloading at the construction site, installing small equipment, components and piping and other small tools. Use lever hoist safety requirements:
  (1) When using the lever hoist, lifting allowed to exceed the allowable load, according to the marks from the weight used.

  (2) When using do not handle any longer, because the lever hoist from the weight is limited, two-handed pull force also has a certain size, longer handle the overload will cause the lever hoist use, resulting in damage to components.

  (3) should always check the rope for wear and kinks, broken wires, broken stocks, which do not meet the safe use must be replaced.

  (4) The working principle of the lever hoist is the use of wire rope clamp clamped alternately, so requires the use of steel core wire rope core and not with hemp rope, hemp core rope due to soft and elastic, after clamping the clamp Easy loosening, is unsafe.

  (5) To ensure the lever hoist safety requirements before use to conduct a comprehensive inspection and testing, maintenance after use.
