Rotary limit switch for Favelle Favco 8/10K

The rotary limit switch is an electromechanical device that monitors and restricts the rotational range of motion for critical crane components. It is commonly used to govern the operation of the trolley travel, winch cable spooling, or boom rotation. By utilizing 6 contacts, the switch generates electrical signals that trigger the slowing or stopping of machine movements once pre-set operational boundaries are reached, ensuring that the crane functions within its defined parameters.

This unit is compatible with the Favelle Favco 8/10K model. It is manufactured by Stromag, a specialist in transmission and control components. The device employs an internal gear system that translates the rotational movement of the input shaft into the activation of its electrical contacts. These contacts allow for various control configurations, including position limits, speed thresholds, and warning signals.

Rotary limit switches serve as a primary safety mechanism in heavy lifting machinery. By preventing mechanical components from exceeding their intended travel limits, these switches help avoid structural damage, collisions, and operational hazards. Proper calibration and periodic inspection of the contact points are required to maintain the functional integrity of the crane control system.
