Inspections and Maintenance: 

 
Interval of inspections should be determined according to the frequency of use and the working 
scenario of the winch.  

Signs of malfunction or poor operation should always lead to an inspection of the winch, and the 
winch should be taken out of operation until the error is eliminated. 
 

 

Maintenance plan: 

 
Before every use and Weekly: 
 

Every time when rigging the winch, before running the winch – and at least every week when the 
winch is in use: 

 

Check the entire length of the wire rope for bends, crushed areas, broken or cut cord, 
corrosion and other damages. 

 

Check all limit switches. 

 

Check the slack detection device 

 

Check the emergency stop. 

 

Check that the wires are winded neatly in the grooves of the drums. 

 
 

Monthly: 
 

At regular intervals – but at least every month when the winch is in use: 

 

Check the mounting clamps for damages and proper fastening. 

 

Make sure the load is secured to the wire with approved fastening. 

 

Clean the grid of the ventilator and air outlet. 

 

Change damaged parts.  

 
 

Every 12 month:  
 

The winch has to be inspected by a specialist every 12 months 
 
 

Every 48 month: 
 

The winch should be inspected by an authorised expert every 48 months. 
 
The results of the regular inspections are to be documented and kept available at the company. 
The written result of the last inspection must be kept available at the site of operation, e.g. by an 
inspection sticker on the winch showing the date of the inspection, the basis of the inspection and 
the name of the inspector.
