The Enerpac HCR4008 is a 400-ton class double-acting cylinder from the HCR-Series high-tonnage range, with a 7.87 in stroke and a maximum capacity of 450 tons at 10,150 psi. As a double-acting cylinder it is powered in both directions, for fast advance and retract and for applications where there is no load to push the plunger back, such as pushing, pressing and pulling.
Features
- Hardened surface that resists side-loading and cyclic wear
- Designed to withstand up to 10% side-load of maximum capacity
- Fast advance and retract
- 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 HCR4008 has an effective area of 88.75 in² and needs 698.79 in³ of oil to advance its full stroke and 234.85 in³ to retract. It is 18.54 in tall collapsed and about 26.41 in extended. Choose a pump with at least 769 in³ of usable oil; a ZE pump with a 5.2 gal (1,201 in³) reservoir or larger covers a single cylinder. Under full load, a ZE4 pump (60 in³/min at 10,000 psi) takes about 11.6 minutes to complete the stroke and a ZE5 (120 in³/min) about 5.8 minutes; under light load two-stage pumps move it much faster.
How it compares
The HCG4008 is the single-acting, load-return version with the same capacity and stroke. Other strokes in the 400-ton HCR range: HCR4002 (1.97 in), HCR4004 (3.94 in), HCR4006 (5.91 in), HCR40010 (9.84 in), HCR40012 (11.81 in).
Before you order: Keep side-load below 10% of maximum capacity; on 400-ton models the collar thread is optional: order HCR4008E002 for a cylinder with collar thread.
