INTRODUCTIONS

DHK electric chain hoists are a kind of new lifting equipment which adopt Germany advanced technique and add technological innovation and change structure. They keep the features of chain hoists’ light and convenience and improve the disadvantages of chain hoists such as manual operation and the slow lifting speed. DHK electric chain hoist not only reserve the legerity of chain hoists, but also are improved from man-operated, integrating the superiority of electric and chain hoists, compact structure, light weight, high efficiency, convenient use, simple maintenance, high lifting speed, smooth running and beautiful appearance. DHK electric chain hoists are driven by the plate type braking motor and decelerated by the reducer. Besides, their unique overloading safety protection setting and electrical machine hot protection setting guarantee the higher reliability of this product. 

The bodies of them are made of  high-strength tensile shell or die-casting aluminum shell, and they are made of  thin wall extrusion molding technology. They are small in volume, light in  weight and high in strength. The standard DHK electric chain hoists are equipped with an independent gearbox system, a two stage coaxial transmission gear mechanism in a sealed gearbox, and a long life oil bath lubrication  system. DHK electric chain hoists' powder metallurgy clutches are used as an overload  protection device, which adopt disc type direct current electromagnetic field  braking. What’s more, the braking torques are large, stable, fast, and the noise is small.

DHK electric chain hoists have the characteristics of  fast lifting speed, convenient operation, beautiful appearance and so on. Especially their unique overload protection settings and electrical reliability of products. Whether it is the standard, the ready-made ship unit or a modification to the customer's specific needs, our electric chain hoists are built on a reliable operation, even in the most difficult application and occasion. From small capacity to heavy duty, our DHK electric chain hoists are built to exceed any hoist in the market.

The most important parts of the DHK electric chain hoists are brake system and chain. Besides, they are driven by the disk type braking motor and decelerated by the reducer. Advanced-design mechanical brake fully makes sure the brake below the possible  overload. What’s more, it is in conjunction with motor brake, which is made up of “double brake system”. This system has the function of ensure safety and durability in hoist operations. Super strong surface hardened chain plays an essential part in the working of hoists. It is necessary to use the reliable chain to lift the loads. Therefore, our products are all equipped with high-quality and perfect-performance chain, which are through the strict test by professional engineers. 

DHK electric chain hoists have unique optimization structure to shorten the distance between the fuselage and the beam, which are suitable for the operation of low level buildings, especially for temporary installation or effective expansion. Besides, they could be used together with trolleys and other DHP hoists, so that the lifting net could be founded better because of its slow lifting speed, improving working conditions and labor efficiency. 

DHK electric chain hoists can be widely used in lifting light and small goods in factories, mines, piers, supermarkets, wharfs, stores and warehouses for lifting. They can also be used in low level space materials circulation system in connection with aerial traveling crane equipment. 

They are also called DHK type high-speed endless chain hoists, endless-chain electric hoists, DHK fast electric chain hoists, DHK model electric chain hoists, electric winch DHK type chain hoists, electric chain hoists with chain bags, DHK electric chain blocks, labor-saving DHK electric chain hoists, DHK type electric chain hoists, DHK electric chain hoist pulley blocks, DHK electric chain hoist lift crane, DHK type high speed endless chain electric hoists, DHK electric lifting blocks, KSY electric chain hoists, KSY electric hoists, KSY powered hoists and KSY hoists.
