On most conventional cranes, how is the power transferred to a torque converter?

The power transfer to a torque converter on most conventional cranes is achieved by a master clutch. A master clutch connects the engine's power to the torque converter, allowing the driver to engage or disengage the power flow based on operational needs. When the master clutch is engaged, it transmits the engine's power to the torque converter, which then modulates it to allow for smoother operation of the crane, enhancing control during lifting and maneuvering tasks.

This method is particularly beneficial in heavy machinery, as it provides a buffer that can absorb shock loads and reduce wear on engine components. The versatility of a torque converter, in conjunction with a master clutch, allows for more efficient power management and smoother changes in speed and direction without stalling the engine.
