A new video has been released by West P&I, detailing the correct procedure for performing a rocking test on pedestal-mounted rotating cranes.
Pedestal-mounted rotating cranes are fitted with slewing bearings to allow 360-degree rotation. The slew bearing is subject to high loads and frequently harsh conditions, which can give rise to rapid catastrophic failure and unwanted consequences, including severe injury or fatalities. Regular tilt clearance measurements (frequently known as The Rocking Test) are essential to identify a failing slewing bearing.
The video below demonstrates the most popular way for accurately performing a rocking test to detect if the slewing bearing is failing and if the crane must be removed from service for repair.
To remind, West Club has other interesting videos that endorse safe practices such as best sampling practices for onboard tankers and how to secure engine room floor plates.
