Resistor bank for Linden Comansa 21LC750/36t

The resistor bank RCIA.2024 serves as a control component within the electrical system of the tower crane trolley. It functions by dissipating excess electrical energy as heat, which allows the control system to regulate the current reaching the motor. This regulation is necessary for managing the speed of the trolley mechanism, ensuring that the operator can move and position loads along the jib with precision and stability.

This component is specifically designed for the trolley assembly of the Linden Comansa 21LC750/36t tower crane. It is engineered to match the motor characteristics and control requirements of this specific model, facilitating predictable speed control during operation. Proper integration of this bank ensures that the trolley responds accurately to operator inputs, which is necessary for handling heavy or sensitive loads effectively on site.

In general industrial crane applications, resistor banks are used in conjunction with electric motors to provide speed control and braking assistance. By introducing resistance into the motor circuit, these units manage the torque and speed profiles of the crane movements, such as hoisting, slewing, or trolley travel. They are built to handle the thermal loads generated during operation and are integrated into the crane's electrical control cabinet to maintain consistent performance across various load conditions.
