Action in the event of defects
Observe the crane during operation for any sudden signs of any defects.
If you discover the following damage or defects to the crane, ancillary equipment, load lifting
gear or the carrier vehicle you must stop crane operation immediately:
•
Defects, damage or cracks on load-bearing parts.
•
Defect bearings.
•
Defects in the hydraulic unit or safety devices.
•
Loose screwed connections
•
Inadequately secured bolt connections.
•
Leaks on hydraulic components or connections.
•
Unusual noises.
•
Unusually quick or slow working movements.
•
Functional errors in the control system.
•
Unusually high temperature of hydraulic components
In the case of the above-mentioned damage or defects safe crane
operation is no longer ensured. There is acute danger of accident
and thus of fatal injury.
The crane may only return to service when the defects have been removed and safe working is once
again assured.
