• Key functions

1.Dump Body Lifting: Provides the high torque needed to raise the truck’s dump body (via the hoist system) at a controlled speed, even when loaded with heavy materials (e.g., 40 tons of iron ore).

2.Controlled Lowering: Works with the truck’s hydraulic valves to regulate the dump body’s lowering speed, preventing sudden drops that could damage the truck or cause material spillage.

3.Durability in Harsh Conditions: Its heavy-duty materials and sealed design resist damage from vibration (common in mining roads), dust, and temperature fluctuations, ensuring long service intervals (typically 5,000+ operating hours).

4.System Compatibility: Designed to integrate seamlessly with Komatsu’s HD-series hydraulic and electrical systems, avoiding mismatches that could cause pressure spikes or motor failure.
