Frequency control of motor speed crane adopts advanced programmable control (PLC) and frequency converter technology, achieve no speed adjustment. Program control to replace the relay and contactor control, ac motor speed control mode adopts frequency control of motor speed, and thus realize the semi-automatic control of crane. Not only can make the control performance is improved greatly, but also can save 25% 40% of electricity.

Though one-time investment is a little larger using Variable frequency speed regulation technology, but the benefits cannot be ignored. Frequency conversion control performance of crane, the crane can completely meet the requirements of various harsh operating conditions, which can improve product yield and quality directly, and thus can indirectly increase the economic benefit. Frequency control of motor speed will also be able to run at low speed for a long time, has the very high positioning precision and efficiency.   

1, Triad transmission system full frequency control of motor speed, lifting operation is more stable.

2, Promote efficiency, save power

3, Can run at low speed for a long time
