Summer, noon, hot sun, the world's largest port - Shanghai port Waigaoqiao pier, traffic, a busy scene. No. 130 shore bridge is in operation, lifting the winch, a giant of more than 30 tons of TEU (note: TEU), under the traction of steel rope, firmly in place. This is also strong and soft, fast and slow transformation, it has been in service for more than 10 years.

It is STEP Inverter that supports the drive and control core of No. 130 shore bridge!

No. 130 Shore Bridge, located at the western end of Waigaoqiao Wharf shoreline, was produced by Zhenhua Heavy Industry, a leading enterprise in the port machinery industry, in 2003. Its lifting height is 22 meters, the height of the machine room is 27 meters, and the load is 40 tons. The original use of imported brands of inverter as a big car, car, lifting, pitching electric drive.

In 2012, due to the aging of the core electrical drive unit and frequent failures, SIPG decided to renovate the existing part of the shore bridge for electrical drive. For a long time, shore drive control has been the domain of international inverter giants. If the domestic brand inverter is used on the shore bridge drive control, the owner must be full of questions about safety and reliability. In such a remote area of domestic brands, want to break the foreign monopoly, for domestic brands is a huge challenge.

The owner held the psychology of trying, made a careful investigation of the STEP, and was surprised to find that the technical indicators of the STEP inverter met the requirements. Therefore, the opportunity to replace the only one of the 27 shore Bridges with domestic production was left to STEP.

Never thought, dare to challenge the impossible of the new time master, and Zhenhua port machinery close cooperation, so that the owner's decision made a new legend in the industry.
