Dongfeng KInland truck spare parts Right hydraulic lock bolt assembly 5002175-C0100

A core advantage of the 5002175-C0100 assembly is its exceptional structural strength, tailored to Kinland’s heavy-load hydraulic operations. The lock bolt is crafted from 40Cr alloy steel, undergoing quenching and tempering (860°C heating + 550°C cooling) to achieve a tensile strength of 800MPa—capable of withstanding 20,000N of axial force without bending or shearing. The lock body is made of cast steel (QT450-10), featuring reinforced ribs at stress points (e.g., bolt insertion hole, hydraulic port) that distribute pressure evenly, preventing cracking under high hydraulic pressure (up to 30MPa). This strength ensures the assembly securely locks hydraulic components (e.g., dump bed cylinders) in place, preventing accidental lowering or shifting when the truck is loaded with 20+ ton cargo—critical for operator safety and cargo protection

The 5002175-C0100 assembly delivers consistent hydraulic lock performance, a key safety feature for Kinland’s hydraulic-dependent applications. It uses a spring-loaded piston design that engages the lock bolt automatically when hydraulic pressure drops (e.g., hose leaks, pump failure), creating a mechanical backup to prevent unintended movement. The lock’s engagement time is ≤0.5 seconds, ensuring rapid response to pressure loss—avoiding dangerous situations like sudden dump bed lowering. When hydraulic pressure is restored, the piston retracts smoothly, releasing the bolt without manual adjustment. For Kinland dump truck operators, this reliability eliminates the risk of cargo spills or equipment damage caused by hydraulic system failures, complying with industrial safety standards (e.g., ISO 13849)

Built to endure harsh operating environments, the 5002175-C0100 assembly features a robust anti-corrosion treatment. The lock bolt and body are coated with a zinc-nickel layer (18-22μm thickness) that passes 1,000-hour salt spray tests, resisting rust and oxidation from road salt, rain, or hydraulic fluid spills—common in construction or mining sites. A top layer of anti-wear lubricant is applied to the bolt’s thread, reducing friction during engagement and preventing seizing due to dirt or debris. The assembly’s hydraulic seals are made of FKM rubber, which maintains flexibility and fluid tightness in temperatures ranging from -40°C to 120°C—preventing leaks in extreme weather. Rigorous aging tests confirm the assembly maintains functionality for 6+ years, outperforming generic locks that corrode or seize within 2-3 years

The 5002175-C0100 assembly is designed for user-friendly installation and maintenance, saving time for Kinland fleet technicians. It comes pre-assembled with the lock bolt, spring, piston, and mounting hardware (nuts, washers), eliminating on-site assembly. The lock body’s pre-drilled mounting holes align with Kinland’s hydraulic system brackets, requiring only a torque wrench to secure (torque specification: 120-130 N·m) and taking 30 minutes or less to install. The assembly’s sealed design requires no regular lubrication or adjustment—only periodic visual inspection of seals and bolts to ensure integrity. For fleet managers, this low-maintenance design reduces upkeep costs and minimizes truck downtime, ensuring Kinland vehicles stay operational for time-sensitive tasks like construction material transport or waste disposal
