Low Clearance. High Force.
Enerpac offers multiple low-height hydraulic cylinder designs for machinery lifting, structural positioning, industrial maintenance and applications where a conventional hydraulic cylinder may be too tall.
Hydraulic Force Where Standard Cylinders Will Not Fit
Low-height hydraulic cylinders are designed for applications where vertical clearance is restricted. Different Enerpac series provide options for extremely low starting heights, increased stroke, telescopic movement, high-tonnage lifting, mechanical load holding and load alignment.
Compact and ultra-flat cylinder designs fit beneath machinery, structural components and equipment where conventional hydraulic cylinders may not have enough clearance.
Low-height options range from compact maintenance cylinders through high-tonnage cylinders for major industrial lifting.
Depending on the series, cylinders use spring return, load return or gravity return for different lifting requirements.
RLT telescopic cylinders provide multiple stages to create more usable movement while maintaining a compact starting height.
LPL low-height lock nut cylinders provide positive mechanical support when a lifted load must remain held after positioning.
Selected low-height cylinder series provide integrated or optional tilt saddles to help accommodate minor load misalignment.

Which Low-Height Cylinder Series Should You Compare?
Compare CULP and CUSP ultra-flat hydraulic cylinders.
Compare RSM for very short lifting movement and RCS where more stroke is needed.
RLT telescopic cylinders provide multiple stages from a compact starting height.
LPL cylinders use an integrated lock nut for mechanical load holding.
CUSP extends ultra-flat hydraulic lifting into capacity classes up to 1000 tons.
Send Northland the load, available clearance, required movement and application details.
The Cylinder Is Only One Part of the Lifting System
Low-height hydraulic lifting equipment must be matched with the correct power source and system components. Northland can help review the complete hydraulic setup before it goes to the job.
Match usable oil capacity, operating pressure, required speed and control requirements.
Use a compatible high-pressure hose and connection arrangement for the selected cylinder.
Confirm cylinder, hose and pump coupler styles are compatible.
Monitor hydraulic pressure and reduce the risk of overloading the cylinder or lifting system.
Multiple-cylinder lifting may require additional flow, pressure and load-control components.
Controlled multi-point lifting may require a synchronized hydraulic system rather than independently operated cylinders.
Low-Height Hydraulic Cylinder Selection Matters
Measure the actual starting space beneath the load and compare it with the cylinder's collapsed height.
Determine how far the load must move. Ultra-flat and telescopic cylinders serve very different stroke requirements.
Select the specific model using the actual load and maximum cylinder rating rather than capacity-class terminology alone.
The cylinder must be placed on a suitable, adequately rated surface capable of supporting the load without instability.
Confirm the pump has enough usable oil for the selected cylinder or group of cylinders throughout the required stroke.
Loads supported at several points may require synchronized lifting equipment, manifolds and additional control components.
Tell Us the Load, Clearance & Required Lift.
Northland can help compare Enerpac low-height hydraulic cylinders and match the selected cylinder with the appropriate pump, hose, pressure gauge, couplers, manifolds and controls for industrial lifting applications in Edmonton, Alberta and across Western Canada.
