Rope length indicator for Grove GMK2550

The rope length indicator, part number 03320584, serves as a control device for monitoring the amount of cable extended from the winch drum. By tracking the payout of the cable, it provides the necessary data for calculating the current lift height and operating radius of the crane. This information is integrated into the load moment indicator system to ensure the machine operates within its designated load chart limits.

This component is specifically designed for the Grove GMK2550 all-terrain crane. It functions by monitoring the movement of the cable and transmitting this data to the crane's processing unit for real-time display and safety calculations. Maintaining the accuracy of this sensor is necessary for the correct interpretation of load and radius data during lifting operations.

In crane systems, a rope length indicator typically utilizes a sensor, such as a rotary encoder or a cable-driven potentiometer, to track the position of the boom head relative to the winch. This measurement is fundamental for the electronic safety systems that prevent overloading and maintain stability during complex maneuvers. Consistent monitoring of cable length allows the crane's control system to adjust load charts based on the actual configuration of the boom and rigging.
