According to harbor power jacking, lifting and other users demands, INVT has provided the most secure, reliable and efficient frequency conversion products and solutions for users to help them solving various challenges.
With the development of automation technology, the floating crane equipment also starts to use the automatic control system. The frequency converter is used as the core driving part for power balance and speed regulation. This article mainly describes the successful application of the INVT Goodrive800 inverter for floating crane.
The traditional hydraulic anti-shake system has a long response time delay, component loss and other issues, seriously troubling the port machine users, with the in-depth promotion of frequency control in the port machine industry, frequency anti-shake system gradually attracts the concern of majority port machine manufacturers and users, and becomes the mainstream of industry applications with its superior torque control performance and solid stability. The rail suspension anti-shake system in this article adopts INVT CHV190 inverter to overcome the lack of hydraulic anti-shake system, which has significantly weaken the spreader swing, marking another major improvement of domestic inverter application in the port machine industry.
This paper analyzes the running characteristics of portal crane, and elaborates the selection principle of motor, inverter and its braking mode and the capacity calculation method of the inverter peripheral equipment when CHV190 crane special inverter is used in portal crane speed adjusting, and finally introduces the application case of CHV190 inverter in portal crane.
