1Product Introduction of Hydraulic Synchronous Lifting System for Steel Structure Grid:

The hydraulic synchronous lifting system for steel structure truss can accurately control the load and lifting speed of the jack, fully realizing the effect of synchronous control of multiple oil cylinders. The hydraulic synchronous lifting system for steel structure truss consists of a control console, an electric control box, a hydraulic pump station, network communication, sensor system, etc,PLCThe multi-point hydraulic synchronous lifting system is mainly used for bridge synchronous lifting or positioning, steel structure grid synchronous lifting, large equipment lifting or lowering, building translation lifting, large oil tanker lifting, heavy object weighing, or tunnel and culvert support projects.

The hydraulic synchronous lifting system for steel structure truss adopts advanced technologyPLCControl, large LCD touch screen display and operation, single person operation, easy to learn, can be connected to a computer for control, achieving a friendly human-machine interface. The electrical control box mainly adopts SiemensPLCComposed of programmable controllers, capable of implementing32Synchronized lifting of hydraulic cylinders, each cylinder's pressure sensor and rope type displacement sensor transmit the load signal and displacement signal of each jack to the programmable controller, which uses a large LCD touch screen operation command to send signals and drive the motor valve group, achieving displacement closed-loop control, force closed-loop control, SiemensPLCThe programmable controller continuously corrects the errors of each hydraulic cylinder jack through pressure and displacement signals, achieving load synchronization and displacement synchronization of each hydraulic cylinder.
