COMMISSIONING

4.5.3 Periodic inspections

Periodic inspections and a related test run should be carried out to a used crane once every one

year and a related test run according to the standard SFS EN 12999 or equivalent should be done

once every four years. The inspection consists of procedures according to the periodic inspection

protocol (Annex 3) and particular attention should be paid to the fatigue, wear, corrosion, or other

damage to the materials resulting from use. In addition it must be checked that structures have not

been essentially modified regarding safety.

In addition to periodic inspections, the crane requires a thorough periodic inspection no later than

10 years after its first commissioning.

When calculating the time for thorough periodic inspections, one should take into account the in-

tensity of the crane's use, damage observed during periodic inspections, repairs carried out, and

any possible type faults in the crane.

In the thorough inspection one should dismantle those safety-relevant parts of the assembly whose

functionality cannot be otherwise reliably checked. One should use non-destructive inspection

methods in the inspection.

* Check the hydraulic oil and the rotating device's oil level and top up if necessary.

* Lubricate the crane if necessary (refer to Maintenance Procedures).

* Visually inspect the crane's mounting screws, shaft mounts, hoses and any possible leaks.

* Check visually the state of the frame and the boom structures of the crane!

* Ensure the management and operation of the safety equipment by running the functions to their

maximum and repair any defects immediately

* Make sure that the STOP- switch is working.



Any use of a damaged or defective crane is prohibited!
