Light and small hand chain hoist is a kind of Jane inexpensive hoisting tools, applicable to infrastructure construction, equipment installation, and dockhoist equipment departments such as agriculture, forestry and water conservancy; Can also be matched with manual monorail trolley for lifting the transport, and liquidity operation is more suitable for places where no manual hoist supply. In 1962, our country has designed SH type chain series of drawings, by first machinery industry department order to targets JB56O 64, then on the basis of a large number of products, except for the use of domestic and abroad. But with the development of science and technology constantly in our country, there have been some new material and new process, the performance parameters of the original chain has lagged behind. During the great proletarian cultural revolution movement, through the use of the production practice and user experience, to improve the products constantly, finally we make it become the HS type chain this new series design, its performance parameters have reached the advanced level. One, main parameters and breed new type series chain blocks is called the HS, H represents the gourds, S representative chain group. Series code is made up of model and tonnage, such as HSS said HS type chain blocks 5 tons. New series chain includes four kinds of the body, through the change of sprocket ratio from 0. 5 tons to 20 tons of total n specification. With 0. 5 tons for a single organism, 2 tons of the body can be 1 ton and 2 tons of two specifications.
