Complete Guide to Synchronized Lifting: How It Works and When to Use It
Synchronized lifting is one of the most advanced technologies for heavy load handling in industrial environments. Unlike conventional crane methods, this system allows controlling multiple support points simultaneously with millimetric precision.
What is Synchronized Lifting?
It's a hydraulic system where multiple cylinders are independently controlled by a PLC (Programmable Logic Controller). The software coordinates force and displacement at each lifting point in real time, ensuring the load moves uniformly without stress concentration.
Key System Components
- Hydraulic cylinders: capacities from 50 to 1,000 tons per point. Double-acting with automatic return.
- Hydraulic power unit: 6, 8, 12, and 16-output units. Working pressure up to 700 bar.
- Control PLC: on-screen monitoring of displacement, pressure, and speed for each cylinder.
- Position sensors: ±0.5 mm precision. Linear encoders resistant to hostile environments.
- Robotic Total Station: real-time topographic verification of load position.
Typical Applications
Synchronized lifting is the preferred solution when:
- The load exceeds available crane capacity (> 500 tons)
- There's no space for conventional cranes (inside plants, tunnels)
- Millimetric precision is required (rotating equipment alignment)
- The load must move horizontally and vertically simultaneously
Synchronized Lifting vs. Conventional Cranes
A direct comparison shows the advantages:
- Capacity: Cranes up to 1,200 tons (with logistics delays). Synchronized up to 40,000+ tons.
- Precision: Cranes ±50 mm. Synchronized ±0.5 mm.
- Space required: Cranes need free swing radius. Synchronized works in situ.
- Cost per ton: For loads > 500 tons, synchronized is 30-50% more economical.
Success Stories
Sandiman has executed over 200 synchronized lifting operations in Chile, including the record 1,500-ton lift at Minera Los Pelambres. Our experience spans mining, bridges, ports, and industrial plants.
