Chain Block

Products Chain Block

Description of products

Chain block is a hand operated device that is able to lift or lower loads. Two type of chain blocks, DS and DH, are available with different capacities and net weight. Both series can be provided in stainless steel or explosion proof version. Please contact us for special specifications.

How to operate

There are two different chains in chain block which are load chain and hand chain. Load chain lifts or lower the loads when the hand chain is pulled. If you want to move the loads side to side, Trolley combined with chain block can be used.

Cautions at use

Chain block is optimized to bear vertical loads. When fixing or pulling a load, upper hook, bottom hook and load chain should be aligned in vertical position in order to bear the safety load.
According to Occupation Safety and Health Acts, hook and load chain of lever Hoist should be replaced if the hook throat opening is stretched by more than 10% or if load chain is stretched by more than 5%. Load chain, hook and chain pin which are directly bearing the load should be checked regularly since stretched length is difficult to measure through visual inspection. Lever Hoists are devices that are easily exposed to risk of overload, be careful when using such devices.

Cautions for product selection

Chain block is not able to lift load above minimum distance (H). Components which are combined with hook should be checked if they are compatible. More information for interference or minimum distance, check the DIMENSIONS(mm) in our catalog

Please specify for order

  • CAPACITY (ex. 1.0TON)
  • Whether CLASS CERT is required or not. (3 to 5 months is required for submission)
  • LOAD CHAIN LENGTH, HAND CHAIN LENGTH
  • PAINTING SPEC. : OPTION

Notice

Hand chain length can be adjusted.
We recommend you to keep a 500mm distance between hand chain and floor to prevent dragging hand chain on the floor.
DS Series

Features

DS chain block is lightening version of DH chain block. Lightness is the strength of DS model but, DH has better safety factor. DS is usually sold domestically however DH is usually used in shipbuilding yard which requires high satisfaction of safety.

DH Series

Features

A lift of up to 4 times the Safety Work Load (SWL) will not cause the breakage of the chain block. This model is safer than DS if overload may occur during usage. Therefore, DH model is an excellent choice for high risk environment such as shipbuilding yard, steel structures construction yard and public works.
