【30-Ton Industrial Lifting Power】Engineered with forged #45 steel and a precision-honed piston, this hydraulic ram delivers a massive 30-ton (66,139 lbs) lifting capacity. It’s built for the most demanding applications in shipbuilding, steel fitting, and heavy machinery alignment, providing reliable force to position hull plates, engines, and structural components. 【Precision Control for Critical Alignment】The 50mm (2-inch) stroke offers fine, controlled lifting increments essential for sensitive alignment tasks. The 6.3cm (2.48-inch) hardened steel lifting pad provides a secure, non-slip surface to grip heavy loads without damage, ensuring perfect placement every time. 【Durably Built for Harsh Environments】Protected by a thick plastic spray coating and featuring a integrated dustproof cover for the ZG3/8" port, this jack resists corrosion, saltwater spray, and abrasive industrial debris. The smooth, rounded base ensures stable contact on uneven surfaces, preventing dangerous slips under load. 【Compact & Portable for Tight Spaces】With a minimal closed height of 7.09 inches and a compact 4.72-inch body, this ram fits into cramped access panels and confined machinery spaces where other jacks can't. The 24.25 lb weight and integrated carrying handle make it highly portable around shipyards and workshops. 【Versatile Single-Acting Reliability】Designed for use with any standard ZG3/8" hydraulic pump, this single-acting cylinder is the go-to tool for: Shipbuilding: Aligning and supporting hull sections and propellers; Railroad: Jacking rails and heavy equipment for maintenance; Manufacturing: Positioning heavy machinery and fixtures; Rescue & Recovery: Vehicle extrication and industrial accident response.
