Tower crane brake alert

摘要

Owners and users of tower cranes are being reminded to ensure crane slew brake release mechanisms are maintained in an efficient state, in efficient working order and in good repair. The advice is part of a safety alert issued by HSE as a result of current investigations into the collapse of two tower crane jibs. The alert states that: "Tower crane jibs are designed to free slew when out of service to avoid high loadings being placed on the crane structure and foundations with risk of failure or collapse. In order that a tower crane can be placed in the out of service condition it is essential that the slew brake release mechanism is maintained in an efficient state.
