![]() ![]() In practice many cranes will not have independent hook load monitoring. ![]() ![]() ![]() The load on the main auxiliary hooks should ideally be monitored separately to ensure no overloading of either the winch arrangement, hook, rigging and load.The lifting points and rigging need to be designed to take the load in direction orientation that will occur during the rotation process.The main auxiliary hook controls should be operated independently.In the absence of OEM manual coverage of single crane dual hook operation, guidance can be sought from the OEM, or a lift engineer. Single crane dual hook operations must be undertaken in accordance with instruction found in the crane operators manual developed by the OEM, as not all crane configurations are designed for single crane dual hook operations. These are similar to multi-crane tailing lifts but have additional unique considerations which should be factored in during the planning stages. Single crane dual hook lifts use both the main and auxiliary hooks of a single mobile crane to simultaneously lift a load and, in general, rotate to a different orientation to the initial lift. The Crane Industry Council of Australia (CICA) recently released guidelines relating to single crane dual hook lifts. ![]()
