HCG15012 Enerpac 150 Ton Single-Acting High-Tonnage Cylinder, 11.81 in Stroke, 168 Ton Max Capacity

The Enerpac HCG15012 is a 150-ton class single-acting cylinder from the HCG-Series high-tonnage range, with an 11.81 in stroke and a maximum capacity of 168 tons at 10,150 psi. As a load-return cylinder, the plunger retracts under the weight of the load once pressure is released, so it suits lifting and lowering where the load itself pushes the cylinder back down.

Features

• Hardened surface that resists side-loading and cyclic wear
• Designed to withstand up to 10% side-load of maximum capacity
• Stop-ring to prevent plunger blow-out
• Weather protected, inside and out
• Upper and lower replaceable bearings support the plunger throughout the stroke
• Certified lifting eyes, base mounting holes and collar threads

Sizing

The HCG15012 has an effective area of 33.14 in² and needs 391.45 in³ of oil to advance its full stroke. It is 19.57 in tall collapsed and about 31.38 in extended. Choose a pump with at least 431 in³ of usable oil; a ZE pump with a 2.6 gal (601 in³) reservoir or larger covers a single cylinder. Under full load, a ZE4 pump (60 in³/min at 10,000 psi) takes about 6.5 minutes to complete the stroke and a ZE5 (120 in³/min) about 3.3 minutes; under light load two-stage pumps move it much faster.

How it compares

The HCR15012 is the double-acting version with the same capacity and stroke. Other strokes in the 150-ton HCG range: HCG1502 (1.97 in), HCG1504 (3.94 in), HCG1506 (5.91 in), HCG1508 (7.87 in), HCG15010 (9.84 in).

Before you order: A load-return cylinder needs the load (or an external force) to retract it; keep side-load below 10% of maximum capacity; a collar thread is standard on this 150-ton class.
