العربيةIndustrial Hydraulic Cylinders for Heavy Loads
Lifting a machine frame, a mould, a bridge section or a heavy platform is less about one big cylinder and more about control: several cylinders sharing the load, moving together and holding position safely.
Fenitsa builds heavy-duty industrial cylinders for lifting, jacking and positioning systems, as standard series or engineered to your load case.
Lifting Capacity by Cylinder Count and Bore
Theoretical capacity at 250 bar.
| Cylinders | Bore | Capacity |
|---|---|---|
| 1 | Ø100 mm | 20.0 t |
| 1 | Ø160 mm | 51.3 t |
| 1 | Ø200 mm | 80.1 t |
| 2 | Ø100 mm | 40.0 t |
| 2 | Ø160 mm | 102.5 t |
| 2 | Ø200 mm | 160.2 t |
| 4 | Ø100 mm | 80.1 t |
| 4 | Ø160 mm | 205.0 t |
| 4 | Ø200 mm | 320.4 t |
Real capacity should include a safety factor — commonly 1.25–1.5 on the rated load for lifting applications — and account for uneven load distribution between cylinders.
Moving Several Cylinders Together
Flow dividers
Split pump flow into equal parts; simple, moderate accuracy.
Mechanical linking
A rigid frame or platen forces cylinders to move together; the frame must carry uneven loads.
Position control
Sensors and proportional valves keep each cylinder at the target position; best accuracy.
Load holding
Pilot-operated check or counterbalance valves on every cylinder prevent a load from dropping.
Design Points for Heavy-Load Cylinders
- Centre of gravityKnow where the load’s weight sits — it decides how much each cylinder carries.
- Side loadGuide the load separately; cylinders should push, not guide.
- BucklingLong lifting strokes need thick rods or intermediate guidance.
- Mechanical lockingFor long holding periods, mechanical supports or lock nuts add a second safety layer.
Our standard hydraulic series are built for 160 bar working and 240 bar test pressure with a 250 bar option, bores from Ø40 to Ø200 mm and strokes up to 5,000 mm, using honed St52 tube and Ck45 rods hard-chrome plated to at least 20 µm. Anything outside that envelope is engineered as a custom cylinder.
Which Fenitsa Cylinder Fits Which Function?
Inspection Routine
What to check, and how often, in this application.
- Before each liftCheck hoses, fittings and load-holding valves.
- During the liftMonitor level between cylinders and stop if one lags.
- MonthlyTest holding: load the cylinders and watch for creep.
- YearlyReseal and pressure-test; inspect rods for bending.
Industrial Hydraulic Cylinders for Heavy Loads – FAQ
How much can a hydraulic cylinder lift?
Capacity = pressure × piston area. A Ø200 mm cylinder at 250 bar lifts about 80 t theoretically; use a safety factor for real loads.
How do I keep several lifting cylinders level?
With flow dividers, a rigid linking frame or electronic position control, depending on the accuracy required.
What stops a heavy load from dropping if a hose fails?
Load-holding valves mounted directly on each cylinder.
Do you build custom heavy-duty cylinders?
Yes — bore, stroke, mounting and valve arrangement are engineered to your load case.
