The PLC Single-Acting Pulse Width Control (PWM) Synchronous Lifting System is an advanced electro-hydraulic lifting solution designed for high-precision synchronous lifting, lowering, weighing, and positioning of heavy structures and equipment. Combining PLC intelligent control, pulse width modulation (PWM) technology, and pressure and displacement closed-loop feedback, the system ensures every hydraulic cylinder moves with exceptional accuracy while maintaining balanced load distribution.
Designed for demanding engineering projects, the system is widely used for bridge bearing replacement, bridge lifting, heavy equipment installation, structural jacking, infrastructure maintenance, and industrial lifting applications.
Available in 4-point, 8-point, 12-point, 16-point, and 24-point synchronization configurations, the system can be customized to meet different project requirements.
Using advanced PLC control with pressure and displacement feedback, the system synchronizes multiple hydraulic cylinders with exceptional accuracy.
Advantages include:
Displacement Accuracy: ≤0.2 mm
Synchronization Accuracy: ≤0.5 mm
The system continuously monitors cylinder displacement and hydraulic pressure through high-precision sensors. The PLC automatically adjusts oil flow to each cylinder, ensuring synchronized movement throughout the lifting process.
Benefits include:
The hydraulic pump output is regulated using Pulse Width Modulation (PWM) technology, allowing precise adjustment of hydraulic flow according to the lifting requirements.
Compared with conventional hydraulic systems, PWM control provides:
Integrated pressure sensors and displacement transducers continuously monitor each lifting point.
The system automatically:
A user-friendly touch-screen interface allows operators to monitor and control the entire lifting process.
Functions include:
Multiple safety features ensure reliable operation during critical lifting projects.

The PLC Hydraulic Synchronous Lifting System is widely used in heavy lifting and structural engineering projects, including:
As a professional manufacturer of hydraulic lifting equipment and synchronized lifting systems, we provide complete lifting solutions for bridge construction companies, engineering contractors, industrial plants, and infrastructure projects worldwide.
Our advantages include:
Each system is thoroughly tested before delivery to ensure exceptional accuracy, safety, and reliability in demanding lifting applications.
A PLC synchronous lifting system is an intelligent hydraulic lifting system that uses a programmable logic controller (PLC) to synchronize multiple hydraulic cylinders. It automatically controls cylinder movement to achieve precise lifting, lowering, and load balancing.
PWM (Pulse Width Modulation) is a control method that regulates hydraulic flow by adjusting the output of the hydraulic control valves. This enables smoother operation, higher positioning accuracy, faster response, and improved energy efficiency.
The system provides synchronization accuracy of ≤0.5 mm, while cylinder displacement accuracy reaches ≤0.2 mm, making it suitable for high-precision lifting applications such as bridge bearing replacement.
The hydraulic system operates at a maximum working pressure of 70 Mpa (700 Bar), providing sufficient power for demanding heavy lifting and positioning projects.
