Did you know that over 29% of crane accidents occur while there is no load on the hook?

Collapsed booms and overturns are the most frequent no-load incident types, perhaps surprisingly, followed by assembly/disassembly incidents and power line contacts.

Modern hydraulic crane configurations with a lot of counterweight may generate higher ground loads at the back when unloaded compared to the front while making a lift – a fact that should not be overlooked when checking the load spreading and ground bearing pressures. Additionally, ground bearing pressures developed during moves between lift positions should be considered for crawler cranes or wheeled cranes (which may be partially of fully rigged).

Out of service requirements for severe weather need to be considered and included in contingency plans to avoid damage to equipment. Extreme cold, wind and lightning should all be planned for at the outset to select equipment which is suitable for the location, environment, and project specifics. Machines should then be used in accordance agreed procedures which match the manufacturers’ recommendations for winterizing, boom lowering, weathervaning etc. Cranes that require superlift to lower the boom require particular consideration, to ensure time is allowed to make preparations in advance of high winds.

At Lowther-Rolton we prepare original lift plan documents and third-party reviews which consider all phases of crane operation from assembly through operation to disassembly, and all aspects of the operation. Our consulting services ensure your construction strategy considers all risks and
