BCR component for Linden Comansa 21LC750/36t

The BCR component, part number TRTA.0201F, functions within the electrical control systems of Linden Comansa tower cranes. It serves as a brake control or brake chopper resistor, which manages the energy generated by electric motors during braking operations. By dissipating this excess electrical energy as heat, the component protects the crane's electronic drive systems and ensures controlled motor deceleration during lifting, slewing, and trolley movements.

This component is specifically engineered for fitment on the Linden Comansa 21LC750/36t tower crane. It is integrated into the braking circuit to support the operation of frequency converters and motor controllers, preventing electrical overloads during dynamic braking cycles. Proper function of this unit is required for the intended operation of the crane's braking systems.

In heavy machinery, brake resistors are used to convert the regenerative electrical energy produced when a motor acts as a generator into thermal energy. This process allows for smooth deceleration and prevents damage to the control electronics by providing a safe path for excess current.
