4.0 PRODUCT DESCRIPTION
Enerpac HCRL-Series cylinders are an ideal solution for a wide
variety of commercial and industrial lifting applications.
HCRL-Series cylinders are double-acting with hydraulic
advance and return. A lock nut provides mechanical load
holding capabilities.
The hydraulic return feature allows greater control during
lowering and provides positive retraction of the plunger. Note
that the HCRL-Series cylinders are not designed for pulling
applications.
Capacities range from 62 to 1196 US tons [550 to 10644 kN].
Refer to the product data markings on the cylinder base for the
capacity rating of your cylinder model.
All standard production HCRL-Series cylinders are designed
for 10150 psi [700 bar] maximum working pressure.
An integrated tilt saddle is standard equipment on all models.
Refer to Section 12 of this manual for cylinder weights, oil
volumes, dimensions and additional specifications.
