Chain by pulling to move the chain

Chain by pulling to move the chain, manual hoist wheel rotation, the friction slice ratchet wheel, brake pressure into one common rotation, short and long axis rotation piece of gear, the tooth axis and the spline gear. So perfectly on the spline gear lifting chain wheel drives the lifting chain, thus hoist equipment promote weight. Unilateral brake friction ratchet type, can self braking under load, ratchet in spring and ratchet gearing, under the action of the brake safety work.

lifting and other materials such as wood handling operation.

Change of different auxiliary work unit can also be bulldozing, lifting and other materials such as manual hoist handling operation. In roads, especially in the construction of high-grade highway, the loader used in subgrade engineering fill dig, asphalt mixture of aggregate and cement concrete chainb lock and loading operations. And also can be a force behind the soil, ground leveling and other machinery operation traction.

Traction weights of small light lifting equipment

Also called the fairy gourd, jin does not fall, manual gourd, is a kind of simple to use, easy to carry the manual manual hoist machinery, also known as chain hoist or chain. It is suitable for small short lifting equipment and goods, the weight is generally not more than 100 t. Shell material is high quality alloy steel chain, strong wear resistance, high safety performance. Manual gourd - hoist equipment gourd refers to using human drive chain and the handle to ascend or traction weight small light lifting equipment. Can be divided into the ring chain and lever blocks, steel wire rope type two kinds.
