Crane Assessment

Wear and tear on cranes is a normal phenomenon that occurs as these cranes are subject to a number of forces. Factors such as corrosion, fatigue and in extreme cases machinery failure can be detrimental to clients’ operations. And can even lead to increased health and safety risks.


1 Crane Portal

1.1 Wheel bogies

Wheel bogies found with all the drive motors including gear boxes and drive pinions removed. Travel motion seems to be taken out of operation for a longer period. To prevent the crane from moving the travel motion is locked by the mechanical operated rail clamps. For any future use the wheel bogies to be inspected to determine if the impact of the collapsed boom caused any damage to the wheel bogies, wheel arrangements and their fixings to the gantry legs. The inspection should cover visual, dimensional, and where required, Non‐Destructive Testing [NDT] on selected critical welds in the main load path. The removed drive motors including gear boxes and drive pinions to be reinstalled or renewed in case the crane travel motion is required.


1.2 Portal legs

For any future use the portal legs to be inspected to determine if the impact of the collapsed boom caused any damage to the portal legs. The inspection should cover visual, dimensional, and where required, Non‐ Destructive Testing [NDT] on selected critical welds in the main load path. Bolting arrangement of the portal legs to the gantry structure to be visual inspected. Renewal of bolts may be required if corrosion is present and beyond acceptable limits.
