Description
Tower Crane Parts Resistance Box
The resistance box is a key electrical component for tower cranes. It controls motor speed and provides dynamic braking for hoisting, slewing and luffing systems. Made of high-temperature resistant materials with excellent heat dissipation and stable performance. Durable structure, suitable for harsh construction environments to ensure crane safe operation.
The tower crane resistance box is a control circuit component of tower cranes. It mainly limits the starting and operating current of the motor, prevents motor overload and burnout, and protects the safety of the tower crane motor and control system.
