SX33105C486B Dump Trailers

Fumin Group, a leading Chinese manufacturer and exporter of heavy-duty commercial vehicles and trailer components, presents the SX33105C486B Dump Trailers — an 8×4 heavy-duty dump truck specifically configured for urban construction muck haulage and road transportation. With an annual production capacity of 150,000 axle assemblies and a facility located in China's largest trailer production base — Shandong Liangshan Boxing Industrial Park — Fumin combines advanced CNC processing with rigorous quality inspection to deliver vehicles that meet world-class technical standards.

The Trailers is built to handle the demanding cycles of construction site loading, road transport, and dump site unloading. Its 8×4 drive configuration provides superior traction and load distribution, making it particularly suitable for heavy muck and aggregate haulage in urban development projects.

Operational Context: Built for Urban Construction & Road Transport

It is deployed across two primary operational environments:

• Urban Construction Muck Haulage: The 1800+4775+1400mm wheelbase and 28° approach angle allow maneuvering within confined city construction sites, while the 8.6m cargo box (2.35m wide × 1.5m high) matches standard excavator loading cycles for efficient muck removal. The 16.1-ton rated payload supports high-volume material transport in urban development projects.
• Road Transportation: The 8×4 drive configuration with 5.262 axle ratio provides stable highway performance, while the 600L fuel tank extends operational range. The 31-ton total mass complies with standard heavy truck road transport regulations.

These operational parameters are derived directly from the vehicle's engineering specifications for these market segments.

How Does the Trailers Solve Heavy Haulage Challenges?

Fleet managers and procurement professionals in the construction sector face daily challenges with vehicle structural fatigue, insufficient payload capacity, and power loss on job site inclines. The heavy-spec SX33105C486B Dump Trailers configuration directly resolves these B2B operational pain points through high-tier industrial component integration.

• Built for Heavy Haulage: Engineered explicitly to manage extreme torque loads, reducing wear on internal gears during continuous dump and transport cycles.
• Reliable Power Delivery: The transmission is matched to the engine's torque curve to ensure smooth and efficient power transfer under full load conditions.

Comprehensive Technical Specifications

To ensure complete transparency and engineering accuracy, the following data table details the exact dimensions, weight ratings, and component specifics of the SX33105C486B Dump Trailers series.

Engineered Structural Strength for Heavy-Duty Use

The SX33105C486B Dump Trailers is reinforced from the ground up to prevent chassis deformation and ensure safe operations on construction sites and unpaved job site roads.

Advanced Axle and Loading Architecture

• Heavy-Duty Steering Stability: The dual front axles each provide an allowable load of 6,500 kg, offering superior steering stability and load-bearing performance under full capacity.
• Massive Rear Axle Casting: The 16T MAN duplex stage rear bridge manages an allowable axle group load of 18,000 kg. This robust casting easily withstands severe impact when heavy rock or muck loads are dropped into the 8.6-meter cargo box.
• Reinforced Spring Suspension: Equipped with a heavy-duty multi-leaf spring configuration to minimize body roll and absorb shock loads during loading and transport.

Optimized Chassis Frame and Job Site Mobility

• Excellent Ground Clearance: An approach angle of 28 degrees and a departure angle of 20 degrees allow the vehicle to navigate construction site entrances, deep ruts, and steep ramps with confidence.
• Premium Tire Grip: Outfitted with twelve 11.00R20 or 12.00R20 18PR high-ply tires that provide maximum puncture resistance and traction on loose soils and construction debris.
• Robust Wheel Track: The 2036mm front and 1860mm rear track widths contribute to vehicle stability during loaded cornering and dump operations.
