The Application of INVT CHA100 Four-quadrant Frequency Inverter in Port Machine

INVT CHA100 four-quadrant frequency inverter in quayside container gantry crane

Quayside container gantry crane has the characteristics including big momentum, four-quadrant and quick speed, which can not only satisfy frequent start, stop and brake, obvious vibration and impact, but also guarantee constant torque smooth speed regulation, and full power output in weak magnetic high speed, and it must also have enough over-load times in low frequency, basic frequency and high frequency etc. In addition, in terms of safety, quayside container gantry crane also has very high requirement to the reliability and stability of frequency inverter.

INVT CHA 100 four-quadrant frequency inverter uses public DC bus line mechanism, high performance vector control technology, PWM rectification and energy feedback technology, which not only satisfies various high performance parameter indexes of quayside container gantry crane, but also meets the requirements of safety, reliability and busy working of the machines at the port. Through more than two years operation in quayside container gantry crane at the port, it proves that INVT CHA100 four-quadrant products can completely meet the requirements of big-size port machines in terms of performance, stability and reliability, which will have extensive application prospect for lifting equipments in many industries like port loading and unloading and shipbuilding etc
