Wire rope lever hoist can be used for hoisting, pulling belt and other work, in daily application is very effort saving, rest assured, safety, convenient and fast. In the circulation system of lifting lifting - clamping lifting - lowering lifting, the effective use of wire rope, the production, processing, manufacturing quality and installation characteristics of parts of clamping structure and traction belt structure affect the application of goods and product quality immediately.

Big pulling force, short travel arrangement: this is also because of the poor quality of the production, processing and installation of traction belt organization.

The actual operation force of the manufacturer of small travel arrangements and separate jacks is mainly caused by the shaking of the remote rod, the swinging Angle of the rocker and the unreasonable reduction ratio of the software of the rod and bar system.

The sound load characteristics of the lever hoist are poor: this is also because of the installation quality of the clamping mechanism. The clamp alligator plate in the rope and unloading part of the wire rope can be arbitrarily put into or removed, and when the clamp alligator plate and wire rope are damaged to the limit specifications, the clamp is still adequate clamping safety performance of the wire rope, mainly determined by the size of the clamp alligator plate and the specifications and parts of the clamping plate. In addition, in order to make the clamping mechanism have sufficient original support force, the mechanical jack manufacturer and maintain the loose unloading lever in the operation part is not loose and become the release of pressure, be sure to choose the torsion spring reasonably.

Using steel wire rope: in the steel wire rope lever hoist, the support force of the steel wire rope is very large, and the clutch jack manufacturer also needs to roll over the relative clamp under the action of support force. Therefore, its damage and lateral deformation is very large. Such as the use of shoddy wire rope not only short cycle, and because of relatively large elastic deformation lead to return too much, sometimes will produce wire rope surface protrusion of the "bubble" situation, harm the normal application.
