Lifting machinery : small light lifting machinery, hoist, hanging the Sheep rail system, in accordance with the characteristics of bridge cranes and overhead cranes, gantry cranes, semi-gantry cranes, jib cranes, mobile cranes, tower cranes, portal cranes and other lifting machinery.
Lifting machinery industry, the biggest market of the inverter application port machinery, port machinery is the highest degree of automation industry segments, in the large shore bridge, a set of inverter 5-6 inverter; followed by General bridge crane market, although not very high proportion of the application of the general bridge cranes, but sets the amount of base; once again for the tower crane market, mainly in large tower crane, tower crane export a higher proportion of applications; addition, metallurgical cranes The proportion is not small; construction elevator and parking equipment market share is still small.
Crane inverter drive overall performance has improved greatly, such as high efficiency, power factor, energy-saving effect is remarkable; simple external wiring, wiring expenses decreased; stepless speed regulation, smooth walking; motor structure is simple high reliability, can be used in harsh environments, greatly reducing the maintenance workload and vulnerable parts, greatly improve maintenance performance; fully functional inverter to protect themselves, such as overcurrent, overload, overvoltage, is able to alarm and stopped, reducing the crane failure, and to improve the safety performance. At the same time, the converter with current limiting, soft start to reduce the impact of the starting grid, help other workshop equipment uptime.
