Pressure switch for Demag AC 615

The pressure switch 69038273 serves as a control device within the bolting system of the Demag AC 615 all-terrain crane. It monitors fluid pressure in the circuit to confirm that structural bolts are correctly engaged and locked before the crane begins lifting operations. By detecting pressure levels, the component ensures that the boom and other structural elements remain properly secured during use.

This component is designed for fitment on the Demag AC 615 model. It integrates into the crane's hydraulic or pneumatic architecture to provide feedback on the status of the bolting assembly. The switch is built to interface with standard pressure connections and electrical systems found on this specific crane model.

In heavy machinery, a pressure switch functions by monitoring fluid pressure in a specific circuit and sending an electrical signal when the pressure hits a pre-set limit. This signal can trigger indicators, alarms, or automated safety stops to prevent operation when pressure is outside of required parameters. These devices are used to maintain operational safety by verifying that critical systems are pressurized correctly before and during machine function.
