5.4. Tires
5.4.1. Maintenance tires
Check the tires rims every week at normal working conditions.
To ensure safety, all tires and rims must be checked regularly for wear and damages. This has to be done on the
outside as well on the inside of the wheels. To get better access, turn the wheels entirely to the left or right using
the steering wheel.
5.4.2. Tire pressure
Check the tire pressure every two months at normal working conditions.
Check all tires for a tire pressure of 10 bar.
Correct this if necessary.
5.5. Check the brake lining thickness
Check the brake lining thickness every year during the yearly maintenance service at
normal working conditions.
To check the brake lining thickness, remove the synthetic sealing caps
at the rear of the brake drums (see Picture 5-10).
Now you can check if the brake lining is still sufficient.
If in doubt make use of the wear ridge to check.
• Proceed by first supporting the crane on outriggers and removing
the wheels.
• Subsequently unscrew the 3 fixing bolts on the brake drums.
•
Then the brake drum is pushed from the hub by means of screwing
3 bolts M12x50 in the respective bores.
• Now check in view of the wear ridge how far the brake lining is
worn and replace it if necessary. The brake lining must be replaced
at a thickness of approx. 8 mm
