The PLC Hydraulic Synchronous Lifting System is widely used in heavy lifting and structural engineering projects, incluido:
As a professional manufacturer of hydraulic lifting equipment and synchronized lifting systems, we provide complete lifting solutions for bridge construction companies, engineering contractors, plantas industriales, and infrastructure projects worldwide.
Our advantages include:
Each system is thoroughly tested before delivery to ensure exceptional accuracy, seguridad, and reliability in demanding lifting applications.
A PLC synchronous lifting system is an intelligent hydraulic lifting system that uses a programmable logic controller (SOCIEDAD ANÓNIMA) 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.
