A new Ultra-Flat hydraulic cylinder series, for projects with small working space, starting at just 2,8 cm, but large lifting requirements up to 1000 ton, was released by Enerpac. The CULP-Series with lifting capacity 10 – 50 ton, and CUSP-Series 10 – 1000 ton, are designed for applications where high lifting forces are needed in confined spaces.

The Ultra-Flat cylinders provide a 7 – 17 mm stroke, with a 700 bar max operating pressure, and are designed to withstand up to 4% side load at full lifting capacity. The CUSP-Series has an integrated tilting function up to 4 degrees, and a 6 – 10mm tilted stroke.

Safety matters

Safety is critical to all Enerpac products. CULP Ultra-Flat hydraulic cylinders are equipped with an internal stop ring that prevents the plunger from accidentally dropping at the end of its stroke. CUSP Cylinders have a “Red Line” as visual indicator to the operator when the maximum stroke has been reached. The CUSP-Series’ tilting plunger can be adjusted enabling equal distribution of load over its full surface. Even at maximum tilted position, most models will have a straight lifting stroke of 10 mm.


All Enerpac cylinders are built to last. In addition to low maintenance requirements, the Ultra-Flat hydraulic cylinders feature a nitro carburizing surface treatment providing greater load and wear resistance, as well as, corrosion protection in the harshest working conditions

The CULP-Series and CUSP-Series Ultra-Flat hydraulic cylinders can be used with Enerpac hydraulic pumps – available in over 1000 different configurations – whatever the application’s requirements for speed, control, intermittent or heavy duty.
