Hitachi's brakes respond to crane applications by reducing braking workload through the use of electric braking in combination.
- If the low-speed operation usage rate is high, the thermal capacity of the motor, IB brake, CF brake, or secondary resistor may become an issue, so please consult our company in this case. - In the case of electrical controls such as IB, DY, and VC control, please use electrical braking in conjunction to reduce the braking work of the mechanical brake during rapid stops from high speed. - For critical applications such as ladle cranes and when using electrical controls like IB, DY, and VC with a motor capacity of 90 kW or more, we recommend using two brakes for one motor to increase the margin of braking force.
Adopting a push-cut type cam switch, a direct controller that achieves high-speed and reliable operation.
This controller is a direct controller that adopts a push-cut type cam switch developed by our company. It uses a special silver alloy for the contacts and incorporates various new ideas into the operating mechanism, resulting in smooth operation. Compared to conventional drum-type roller systems, it offers faster and more reliable engagement and disengagement, significantly increasing its lifespan. The operation is performed using a crank handle, allowing for reversible motor operation and secondary resistance short-circuiting, making it suitable for smooth acceleration and deceleration control.
