Enerpac GBJ003A Hydraulic Bottle Jack 4.125in Stroke

Product Description

The ENERPAC GBJ003A is a manual hydraulic bottle jack designed for controlled lifting in industrial and mechanical service applications. It operates on a hydraulic bottle jack mechanism with a piston stroke of 4.125 inches and a screw size of 2.56 inches, giving the technician both powered lift and fine-position adjustment at the top of the stroke. Weighing 8.1 pounds and compact in profile, this unit suits confined-space lifting tasks where a floor jack or overhead hoist is impractical. It is installed and operated by millwrights, pipefitters, HVAC mechanics, and general maintenance technicians.

The GBJ003A is suited for residential and light commercial maintenance scenarios where short-stroke, precise vertical lifting is required. Typical applications include repositioning mechanical equipment, supporting loads during alignment work, and assisting with component removal and reinstallation in tight quarters. The compact footprint makes it practical on elevated platforms, within equipment bays, and in areas with restricted overhead clearance.

Key Features

• 4.125 inch piston stroke for controlled vertical lift range
• 2.56 inch screw extension for fine height adjustment beyond piston travel
• Manual hydraulic bottle jack operation requiring no external power source
• Compact package dimensions of 6.61 inches height, 4.57 inches width, and 2.95 inches length for use in restricted spaces
• Lightweight at 8.1 pounds for easy transport and single-technician handling

Compatibility

Designed as a manual hydraulic bottle jack for general industrial and mechanical maintenance lifting applications where a compact, short-stroke jack is required.

Installation Notes

Always position the jack on a firm, level surface before applying load. Relieve all system pressure and secure any supported equipment with appropriate safety stands before working beneath or adjacent to a lifted load. Inspect the jack for hydraulic leaks, damaged seals, or structural deformation before each use. Service and load rating verification should be performed by a qualified technician in accordance with applicable ASME and OSHA lifting equipment standards.
