Construction machinery lifting jack components include hydraulic cylinders, pistons, bushings, washers, and safety valves, manufactured from high-precision alloy steel and aluminum. Cylinder working pressure is up to 320 bar, and operating temperature ranges from minus 40 to plus 120 degrees Celsius. Piston rods and shafts are induction-hardened to 55 Rockwell C to enhance wear and fatigue resistance. Bushing dimensional tolerance is below 0.005 millimeters to ensure smooth, backlash-free operation under heavy dynamic loads.
The weight of each lifting jack component set ranges from 12 to 85 kilograms depending on capacity, with assembly using grade 10.9 bolts. Internal lubrication is provided by high-pressure, high-temperature hydraulic oil to reduce friction and wear. Safety and flow control valves operate at 250–320 bar to maintain lifting system security. Service life under standard operating conditions exceeds 12000 hours, and geometric design is optimized using CAD software and FEA analysis.
