New Tower crane Safety Alert
Given the unprecedented situation with the coronavirus outbreak, the CPA Tower Crane Interest Group has issued advice relating to how tower cranes should be left out of service for lengthy periods of time. The new safety alert states that failure to take the crane out of service in line with manufacturer’s instructions and failure to periodically inspect it whilst out of service could result in the crane being subject to very high wind loadings and consequential collapse of the jib or whole crane.

The safety alert sets out advice for leaving tower cranes out of service for long periods of time, namely:

Ensure that the most up to date information for taking the crane out of service is obtained from the manufacturer or supplier for the specific make, model and configuration of crane. This should be checked against the information recorded in the project lift plan.

From the information provided verify that the crane has been left in the correct out of service condition.

With luffing cranes, it is strongly advised that the jib is parked at the maximum out of service radius possible - allowing for surrounding obstacles - rather than at the minimum out of service radius specified by the manufacturer.
