construction machinary spare part
Construction machinery spare parts include mechanical, hydraulic, and electrical components for bulldozers, excavators, graders, and loaders. Mechanical parts such as gears, shafts, and crankshafts are made of alloy steel with 50–60 HRC hardness and tensile strength of 800–1200 MPa. Hydraulic components, including cylinders, pumps, and high-pressure valves, are designed to withstand 250–350 bar. Bearings and bushings with ISO H7 precision and continuous lubrication provide service life over 10,000 hours. Cables and wiring have heat-resistant insulation up to 150°C and high mechanical durability.
Structurally, spare parts include metal frames and chassis, axles and gears, braking systems, hydraulic steering, fuel pumps, and air/oil filters. Consumables like belts, washers, O-rings, and hydraulic filters are industrial standard. Precise and balanced design reduces vibration and extends machinery lifespan. These spare parts are essential for stable performance, operator safety, and optimal maintenance in industrial construction and roadwork projects.
