4.0 PRODUCT DESCRIPTION
Enerpac LPL-Series low height lock nut cylinders are an ideal
solution for a wide variety of commercial and industrial lifting
applications.
All LPL-Series cylinders are single-acting, with hydraulic
advance and load return. An integral lock nut allows the load
to be mechanically supported when hydraulic pressure is
relieved.
Capacities range from 68 to 575 US tons [606 to 5114 kN].
Refer to the product data markings on the cylinder base for the
capacity rating of your cylinder model.
All standard production LPL-Series cylinders are designed for
10150 psi [700 bar] maximum working pressure.
The LPL-Series cylinders have no stop ring. A maximum stroke
indicator line alerts the user when the plunger has reached its
full allowable extension. In addition, a built-in stroke limiter
port relives hydraulic pressure in the event that the plunger
maximum stroke limit is exceeded.
An integral tilt saddle is included on all models.
Refer to Section 11 of this manual for cylinder weights, oil
volumes, dimensions and additional specifications.
