Motor protection for cranes

Working reliably with KRIWAN

The electric motors integrated into the cranes and other lifting equipment are subject to extreme loads: A high number of starts/stops and high speeds of rotation during startup require maximum performance, weakening the motors.

Motor protection solutions from KRIWAN, primarily the INT69 Diagnose, provide optimum protection for electrical units. Critical situations are identified quickly and reliably, and the applicable motor is shut down automatically to avoid motor damage.

At the same time, the collected operating data can, for example, be evaluated via the INTspector app. This indicates possible risks and critical failure/safety shutdown. Depending on the requirements, modules are available with various functions.
