What safety feature automatically shuts off each operational mode of the MHU-204/M and the MHU-196/M lift trailers?

The deadman switch is the correct safety feature that automatically shuts off each operational mode of the MHU-204/M and the MHU-196/M lift trailers. This feature is designed as a safety mechanism that requires continuous pressure or activation by the operator to keep the equipment operational. If the operator releases the switch or loses control, the system will automatically shut down, reducing the risk of accidents or injuries. This built-in safety ensures that equipment operates only when actively controlled by an operator, preventing unintended movement or operation.

In the context of using lift trailers where precise control is crucial, the deadman switch is essential for maintaining safety protocols and protecting both personnel and equipment during operations. Other options like a remote emergency shut-off switch typically require an external action to disengage power, which can be less immediate than the automatic nature of the deadman switch. An operator alert signal is more about alerting the user rather than shutting down the system, while an automatic timer shutdown would not necessarily be responsive to immediate operator control changes, which is integral to safe operation.
