ISUZU GIGA 20Ton Dump Truck

1. Lifting the Cargo Compartment

• The hydraulic cylinder pushes the front of the cargo compartment upward, creating a tilt angle (typically 45°–50°), allowing the cargo to slide out under gravity for efficient unloading.

2. Power Transmission

• Converts the pressure generated by the hydraulic pump into mechanical energy, extending the piston rod of the cylinder to provide sufficient lifting force (often capable of supporting loads of tens of tons).

3. Stability Control

• The hydraulic system, through valve and pipeline design, ensures a smooth lifting process, preventing sudden drops or vibrations of the cargo compartment.

1. Simple Structure, High Reliability

• The front-mounted hydraulic system (single or dual cylinders) has a compact structure, installed between the cab and cargo compartment, with fewer failure points and easy maintenance.
• Compared to mid-mounted or side-mounted hydraulic systems, the front-mounted cylinder bears force more directly, minimizing cargo compartment deformation during lifting, making it suitable for heavy-duty applications (e.g., mining, sand and gravel transport).

2. High Lifting Capacity, Suitable for Heavy Loads

• Front-mounted cylinders typically adopt a multi-stage telescopic design (e.g., 3–4 stages), providing a longer stroke within a limited space, with lifting capacity exceeding 100 tons, meeting the demands of large dump trucks.

3. High Operational Efficiency

• The hydraulic system responds quickly, with cargo compartment lifting typically completed within 15–30 seconds, reducing unloading cycles. The descent speed can be adjusted via hydraulic valves to avoid impact.

4. Optimized Space Utilization

• The front-mounted layout does not occupy space beneath the cargo compartment, facilitating vehicle modifications (e.g., adding heating or sealing devices) without interfering with chassis components (e.g., drive shafts, suspension systems).

5. Enhanced Safety

• Equipped with hydraulic locking valves and emergency lowering devices, ensuring slow descent even in case of hose rupture to prevent sudden cargo compartment collapse.
• During lifting, the vehicle's center of gravity shifts forward, providing better stability than mid-mounted systems (which may cause rear tilting).

• Heavy-Duty Dump Trucks: Such as mining dump trucks and construction waste trucks, requiring high lifting capacity and reliability.
• Long Cargo Compartment Models: The front-mounted system adapts well to varying compartment lengths, distributing bending moments more evenly during lifting.
• Rugged Terrain: In uneven work environments, the front-mounted structure offers better torsional resistance, reducing hydraulic system leakage risks.
