Enerpac RACH and RARH Hydraulic Cylinders

Enerpac's RACH and RARH Series aluminum hollow plunger cylinders, commonly known as hydraulic or center-hole cylinders, offer engineers a portable and lightweight solution for tasks such as lifting and tensioning.

Key features of these cylinders include:

• Capacity of up to 150 tons
• Sturdy yet lightweight construction
• Hollow shafts for pulling and tensioning
• Compatibility with a wide range of pumps

The RACH and RARH Series aluminum hollow plunger cylinders offer engineers a portable tool suitable for various applications, including lifting, tensioning, pulling, pull testing, maintenance, and more. These hydraulic cylinders boast a robust yet lightweight aluminum construction, facilitating easy transportation between projects in construction, manufacturing, and other industries. The RACH model is a single-acting cylinder, while the RARH is a double-acting model. Despite their differences, both hydraulic cylinders share the same features. However, the RARH model stands out with its quicker and more controlled contraction, along with a lighter weight attributed to its lower collapsed height.
          Each cylinder model is equipped with a threaded collar inside the plunger, enabling convenient attachment of accessories or threaded rods. With capacities ranging from 20 to 150 tons and strokes spanning 2 to 10 inches, these cylinders are rated for pressures up to 10,000 psi. The hydraulic cylinders feature a high-strength return spring, ensuring swift retraction. They find applications in rod and cable pulling, tensioning, rock-bolt testing, shaft removal, and more. Both models are compatible with various pump types, including hand pumps and split flow pumps, as well as Enerpac's EVO-Series synchronized lifting systems.
