Dongfeng Kinland truck parts Right hydraulic lock bolt assembly 5002175-C0108

A core advantage of the 5002175-C0108 assembly is its exceptional load-bearing capacity, tailored to Kinland’s heavy-duty operating demands. The lock bolt is forged from 40CrNiMo alloy steel, undergoing quenching and tempering (880°C heating + 560°C cooling) to achieve a tensile strength of 850MPa—capable of withstanding 22,000N of axial force without bending or shearing. The lock body is cast from ductile iron (QT500-7), featuring reinforced ribs at high-stress areas (bolt insertion hole, hydraulic port) that distribute pressure evenly, preventing cracking under 32MPa hydraulic pressure (Kinland’s typical system pressure for dump trucks). This strength ensures the assembly securely locks hydraulic components (e.g., a 25+ ton dump bed) in place, preventing accidental lowering or shifting—critical for protecting operators, cargo, and surrounding equipment from safety hazards

The 5002175-C0108 assembly integrates a dual-protection design to eliminate hydraulic system failure risks. It uses a spring-loaded piston that automatically engages the lock bolt when hydraulic pressure drops unexpectedly (e.g., hose leaks, pump malfunctions), creating a mechanical backup to stop unintended movement. The lock engages in ≤0.4 seconds—fast enough to prevent sudden dump bed lowering or door opening during pressure loss. When hydraulic pressure is restored (e.g., after repairing a leak), the piston retracts smoothly, releasing the bolt without manual adjustment. This dual safety mechanism complies with industrial safety standards (ISO 13849-1 for safety-related control systems) and gives Kinland operators peace of mind, especially when working with heavy cargo or in high-risk construction zones

Built to withstand tough operating conditions (rain, road salt, hydraulic fluid spills, construction dust), the 5002175-C0108 assembly features a robust anti-corrosion system. The lock bolt and body are coated with a zinc-nickel layer (20-24μm thickness) that passes 1,200-hour salt spray tests—resisting rust and oxidation even in coastal regions or winter environments with deicing salts. The bolt’s thread is pre-lubricated with high-temperature anti-seize compound (operating range: -40°C to 200°C), reducing friction during engagement and preventing seizing due to dirt or debris buildup. Hydraulic seals are made of FKM rubber, which maintains flexibility and fluid tightness in extreme temperatures, avoiding leaks that could compromise lock performance. Rigorous aging tests confirm the assembly functions reliably for 7+ years, outperforming generic locks that corrode or seize within 2-3 years

The 5002175-C0108 assembly is designed for hassle-free use, minimizing Kinland truck downtime. It comes fully pre-assembled with the lock bolt, spring, piston, hydraulic seals, and mounting hardware (10.9-grade hex nuts, lock washers)—no on-site assembly or crimping required. The lock body’s pre-drilled holes align with Kinland’s right-side hydraulic brackets, and installation takes just 30 minutes for a single technician using a torque wrench (specification: 120-130 N·m). The assembly’s sealed design requires no regular maintenance—only periodic visual checks of seals and bolt tightness—to ensure optimal performance. For fleet managers, this low-maintenance design reduces upkeep costs and keeps Kinland trucks operational for time-sensitive tasks like construction material transport, waste disposal, or mining operations
