HCR100012 Enerpac 1000 Ton Double-Acting High-Tonnage Cylinder, 11.81 in Stroke, 1196 Ton Max Capacity

The Enerpac HCR100012 is a 1000-ton class double-acting cylinder from the HCR-Series high-tonnage range, with an 11.81 in stroke and a maximum capacity of 1196 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 HCR100012 has an effective area of 235.68 in² and needs 2,783.65 in³ of oil to advance its full stroke and 1,121.51 in³ to retract. It is 27.24 in tall collapsed and about 39.05 in extended. Its oil requirement is larger than a 10.3 gal ZE reservoir, so it needs a large-capacity power unit. Under full load, a ZE4 pump (60 in³/min at 10,000 psi) takes about 46.4 minutes to complete the stroke and a ZE5 (120 in³/min) about 23.2 minutes; under light load two-stage pumps move it much faster.

How it compares

The HCG100012 is the single-acting, load-return version with the same capacity and stroke. Other strokes in the 1000-ton HCR range: HCR10002 (1.97 in), HCR10004 (3.94 in), HCR10006 (5.91 in), HCR10008 (7.87 in), HCR100010 (9.84 in).

Before you order: Keep side-load below 10% of maximum capacity; on 1000-ton models the collar thread is optional: order HCR100012E002 for a cylinder with collar thread.
