The Enerpac HCG2004 is a 200-ton class single-acting cylinder from the HCG-Series high-tonnage range, with a 3.94 in stroke and a maximum capacity of 223 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 HCG2004 has an effective area of 43.95 in² and needs 173.02 in³ of oil to advance its full stroke. It is 11.06 in tall collapsed and about 15.00 in extended. Choose a pump with at least 190 in³ of usable oil; a ZE pump with a 1.2 gal (277 in³) reservoir or larger covers a single cylinder. Under full load, a ZE4 pump (60 in³/min at 10,000 psi) takes about 2.9 minutes to complete the stroke and a ZE5 (120 in³/min) about 1.4 minutes; under light load two-stage pumps move it much faster.
How it compares
The HCR2004 is the double-acting version with the same capacity and stroke. Other strokes in the 200-ton HCG range: HCG2002 (1.97 in), HCG2006 (5.91 in), HCG2008 (7.87 in), HCG20010 (9.84 in), HCG20012 (11.81 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 200-ton class.
