Replacing the load chain 

   

CAUTION!

 

If there is any visible damage and when the conditions for replacement are reached (i.e. one or several 
dimensions in the table have been reached, there is corrosion or elongation), the chain must be replaced.  
When replacing the chain, also check the chain wheels. 
Procedure: 

ƒ

  Only insert new chains in an unloaded state and as the chains that are currently in the device – i.e. not 

twisted. 

ƒ

  Remove chain from its fastening at the end and attach a chain link which is open at the side. 

ƒ

  A chain link which is open at the side, can 

easily be produced by grinding out a small 
piece. The opening must have the same 
thickness as the chain link. 

 

Illustration 4 

 

ƒ

  Hang a new original chain (same size and oiled) in the side opened chain link and insert it. 

ƒ

  Make sure the chain is not installed twisted. 

ƒ

  Make sure the chain links are aligned in one direction. 

ƒ

  Assemble the chain to the end fastening. 

 

12 Inspection 

 

 

12.1 Periodic 

checks 

Independently from the regulations of the individual countries, lifting devices must be checked at least yearly 
by a qualified person or licensed qualified person regarding its functional safety.  

 

12.1.1 

Components to be checked 

The following must be checked: 

ƒ

  Dimensions of load chain, load hooks, pawls, bolts, ratchet wheels, brake linings. 

 

The dimensions must be compared to the dimensions in the tables. 

ƒ

  A visual inspection for deformations, cracks and corrosion must be carried out.

Brake - check wear of brake lining 

 

 

 

 

Check chain wheels, ratchet wheels and pawls. 

 

 

 

 

Clean and lubricate the load chain. 

 

 

Check the load chain for elongation and wear 

 

 

 

 

Check the load hook for cracks and deformation 

 

 

 

 

Load hook - check the safety catch 

 

 

 

Check and lubricate the bearing of the chain pulleys. 

 

 

 

Check the chain pulleys 

 

 

 

Have the equipment checked by a qualified person 

(periodic inspection) 

 

 

 

 

 

 

   

WARNING!

 

If one or several of the dimensions fall below or exceed the dimensions in the table, or if cracks or 
corrosion are found, the parts must be replaced with original spare parts.
