Lever hoist is a kind of hoisting wire rope drawing tools

Lever hoist is a kind of hoisting wire rope drawing tools, when working by hand pull (handle, alternative action by rocker, connecting rod in the clamping mechanism, driving load forward or backward. Because there is no brake lever hoist wire rope, so the clamping mechanism is grasping mechanism brake mechanism, is the key to this kind of product. Design lever hoist wire rope, the main problem is the design of clamping mechanism is calculated. Since there is no uniform design specification, we are updated according to many years of three generations of the product design, test and manual hoistexperience, the design and calculation method of the following are put forward. These data and the method also can be used for reference in the other wire rope in the design of clamping mechanism. A basic size, clamp, clamp plate calculation of the clamping lever hoist mechanism by the clamp, the clamping plate and pin shaft with clamping plate connections side panel, etc. Pull (forward) the handle, the size of the connecting rod drives the side panel for chainb lock motion, a pair of side panel, the other a pair of side plate back; Forward that lateral plate clamping plate.
