The standout feature is its ultra-high pressure capacity,optimized for use with hand-held high-pressure pumps.Often single-acting with spring or load return,making it simple and highly reliable.A built-in mechanical lock nut or collar allows the load to be mechanically locked in position after reaching the target stroke,safely holding it without continuous pressure.Corrosion-resistant surface treatment suits worksite environments.Equipped with quick-disconnect couplings for easy pump connection/disconnection.Some models include a safety relief valve to prevent overload.Lightweight for easy portability to the work site.
Operating pressure is extremely high,commonly 70 MPa to 150 MPa or more.Strokes are typically short,from tens to a couple hundred millimeters,to maintain rigidity.Lifting capacity ranges from a few tons to over a hundred tons.The cylinder barrel uses ultra-high strength material,often autofrettage-treated to withstand extreme internal pressure.The plunger/piston rod is relatively thick to handle high loads without buckling risk.Various top caps(flat,spherical,threaded)are available to suit different load surfaces.
Widely used in equipment maintenance,installation,and construction.In equipment repair,for lifting heavy machinery and alignment adjustments.In construction,for bridge synchronous lifting and structural stress introduction.In power maintenance,for cable tensioning and insulator installation.In manufacturing,as simple pressure testing fixtures or clamps.An indispensable portable power tool for on-site operations like emergency rescue and rail transit maintenance.
