MENOMONEE FALLS, Wis. (January 26, 2021) – Enerpac is adding higher tonnage cylinders to its RARH double-acting hollow aluminum cylinder line. The new 100- and 150-ton models are available with a stroke choice of 50 mm (2”), 150 mm (6”), or 250 mm (10”). The cylinders offer all the benefits provided by the 30- and 60-ton models launched last year.

 Enerpac hydraulic cylinders are used for lifting projects across a wide range of industries – including construction, manufacturing, mining and offshore industries. Each project presents different challenges, and no single cylinder can suit every job. Many projects require a high level of control and the positioning of cylinders in hard-to-reach areas. The expanded line of Enerpac RARH series cylinders is designed for these challenging projects.

Portability and convenience

The RARH cylinders include tough aluminum construction which provides a lower weight solution as compared with steel cylinders. Performance and durability are not compromised by their reduced weight—with each cylinder meeting the ASME B30.1 standard and incorporating a built-in safety valve to prevent over-pressurization. Getting the cylinders into position and into smaller spaces is assisted by the integral handles on each model and their lower collapsed height.

Double-acting for more control

The RARH cylinders are double-acting, which means heavy loads can be lifted and lowered with precise control. A double-acting cylinder outputs force both in and out, creating a higher control level for the retraction that is more reliable, faster, and easier to control than a spring return system. The cylinder can be retracted more efficiently than equivalent single-acting types which use a spring return.

Features and benefits include:

  • Lighter and shorter collapsed height than equivalent RACH single-acting models
  • Double-acting for rapid retraction, regardless of hose lengths or system losses
  • Built-in safety valve prevents accidental over-pressurization
  • Hollow plunger design allows for both pull and push forces
  • Composite bearings increase cylinder life and side load resistance
  • Hard coat finish on all surfaces resists damage and extends cylinder life
  • Handles included on all models
  • Floating center tube increases seal life
  • Steel baseplate and saddle for protection against load-induced damage
  • Integral stop ring prevents plunger over-travel and can withstand the full cylinder capacity
  • Optional internally threaded saddles allow a threaded bar to be pulled directly with the cylinder
  • CR400 couplers and dust caps included on all models
  • All cylinders meet ASME B-30.1 standard
