High Tonnage Ultra Flat Hydraulic Cylinder, 450.5 Tons Capacity, 0.57" Stroke
Enerpac CUSP-Series High Tonnage Ultra Flat Cylinders are an ideal solution for lifting applications in which short stroke and low collapsed height are required, and where non-parallel loading surfaces are present.
All CUSP-Series cylinders are single-acting with hydraulic advance and load return. The maximum angle of the tilting plunger is between 2 and 4 degrees.
Capacities range from 10 to 1000 tons [97 to 10165.4 kN]. Refer to the product data markings on the cylinder base for the capacity rating of your cylinder model.
All standard production CUSP-Series cylinders are designed for 10,150 psi [700 bar] maximum working pressure.
The CUSP-Series cylinders have no stop ring. A maximum stroke indicator line alerts the user when the plunger has reached its full allowable extension.
