30 ton Hydraulic Hollow Jack Cylinder with 2’’ Stroke: A Powerful Industrial Lifting Jack for Portability and Automatic Retraction

About this item

• TECNICAL PARAMETER---Tonnage: 30 ton; Stroke: 2”/50mm; Bore diameter: 1.3’’/34mm; Self height; 6.7”/170mm; Protrusion height: 0.5”/12mm; Outer diameter: 4.4’’/113mm; Inner diameter: 3.6’’/92mm; Spindle outer diameter: 2.6’’/66mm; Weight: 27lb; Used with Pump: cp-700.
• HOLLOW RAM JACK---Compared to ordinary hydraulic jacks, hollow jacks offer improved pressure retention and greater stability. Additionally, the hollow jack features a thickened inner wall design which reduces the risk of oil leakage and extends its lifespan. With its dual shafts, one for pushing and the other for lifting, the hollow jack requires minimal effort to operate effectively.
• RETRACT AUTOMATICALLY---This particular hollow jack starts with an initial protruding stroke of 12mm, which extends to a maximum stroke of 2"/50mm once fully lifted. For added convenience, the main shaft of the jack will retract automatically after pressure is released. Overall, this feature-rich design makes it an ideal choice for a wide range of lifting applications.
• SMOOTH LACQUER SURFACE & ANTI-DUST COVER---The hydraulic ram features a protective lacquer coating to prevent rusting and ensure long-term durability. Constructed from heavy-duty metal materials, this hydraulic cylinder is built to withstand challenging conditions and rugged use. Additionally, the inclusion of an anti-dust ring further reduces the risk of pollution and prolongs the lifespan of the hydraulic cylinder.
• WIDE APPLICATION---This jack provides flexibility in usage, with unlimited directionality and the ability to adjust the angle to match the specific lifting environment. It is equally effective for horizontal or vertical lifting, making it highly adaptable to a wide range of user needs. In addition, this jack is capable of both thrust and tension, providing dual functionality for even greater versatility in lifting applications.
