14) Inspection of the condition of the chains
Tools will be required to perform this procedure.
New parts will be required to perform this procedure.
Dealer service will be required to perform this procedure.
You will need:
Standard tool kit
Protective goggles
Gloves
Place barriers around the perimeter of the work area
Preliminary operation
The disassembly should only be carried out when the chains are completely disconnected and must
be done by people who have the necessary training.
All the precautions must be done before working on and near the machine. After completion of work,
all the covers and safety devices must be positioned back completely and operational.
Lubrication
Lubricant must be applied with a brush to the external chains at least every 250 hours or every 6
months. The frequency of application depends on surrounding conditions and conditions of use. The
frequency of application must ensure that a sufficient quantity of fluid oil is present in the chain links.
If the chain has been exposed to corrosive fluids, clean the chain immediately and apply lubricant.
Note:
Telescoping operations may be necessary to access elements.
Before applying new lubricant, remove any foreign particles from the chain.
When cleaning chains, follow regulations concerning the environment.
Check the condition of the chains
To carry out the following operations, perform a complete telescoping.
Check that the lifting chains and safety chains are clean.
Check that there are no foreign particles on the chains and guide.
Check that there are no signs of corrosion on chain elements.
Chains with any of the defects described below must be replaced.
Check for elongation wear:
Elongation of up to 2%, over 12 segments, of the original chain length is permitted.
Measure the value of (3) using an appropriate method. Compare with the value of 4 indicated in
