Chains for mechanical and hand operated chain hoists

Our chains for chain hoists are internationally recognized for their high quality and versatility and long life. All chains are manufactured under strict norms and all comply with industry standards.

When choosing a chain for a chain hoist, it is necessary to take into account the construction of the hoist, the weight of the load meant to be lifted and the environment in which the hoist operates

Chain operation

Chains should be handled just like any other machine element. It is recommended to avoid dragging the chains along the floor or subjecting them to atmospheric effects, overloading and performing non-professional repairs on them.

In order to achiever maximm life, hoisting chains must be lubricated especially in locations where chains come in contact with sprockets. Hoisting chains need to be kept clean, so that impurities and dirt do not obstruct free movement of the chain.

When handling a load, it is necessary to follow these rules:

  • It is forbidden to use hoisting chains as binding chains
  • Hoisting chains may not be overloaded
  • Hoisting chains must be led straight along sprockets, without twisting
  • Loads must be attached properly in order to protect them from slipping out
  • Hoisting chains must be protected from shocks and jerks
  • It is forbidden to use the chain when links are deformed or worn-out
  • It is forbidden to use the chain to fix loads by looping or by under-running

T and DAT designs

The T design is specifically recommended for use in hand-operated hoists or in low-speed motorized hoists working in highly abrasive environments.

The DAT design is recommended for use in high-speed motorized hoists. This type of chain possesses higher abrasive hadness in comparison to the core hardness, hence it is more wear-resistant. This type of chain is not suitable for use in portable hand-operated hoists.

Temperature ranges

Chains for chain hoists can be used with respective load limitations only within a specific temperature range. This range depends on the type of chain.

Load bearing capacity

The maximum load-bearing capacity for which a chain can be used is defined in technical standards of the respective chain norm. When using hoisting chains, it is necessary to comply with the respective construction and operating parameters of the hoist (eg. drive group, hoisting and lowering speeds, number of teeth in the sprocket). The hoist manufacturer specifies the grade and design of the chain meant to be used in the hoist.
