The SUNHUNK Semi-Trailer Dump Truck with U-shape dump body and 202-5 hydraulic hoist, equipped with 12.00R20 tires and lightweight configuration, is designed to meet transportation demands for construction materials, land leveling projects, and mining operations.
Exterior Design of SUNHUNK Semi-Trailer Dump Truck
The SUNHUNK Semi-Trailer Dump Truck features a powerful and robust appearance. The SUNHUNK dump trailer is manufactured using K450 high-tensile steel – a material with impact resistance and abrasion resistance many times superior to conventional materials.
The dump semi-trailer is equipped with genuine 13-ton axles with high load-bearing capacity.
Rear lighting system is fully equipped. Both rear lamps and side marker lamps are protected with safety mesh guards. The license plate lamp is integrated with reinforcement plates to increase chassis frame rigidity.
Cargo Body
Overall Design
The cargo body is designed with a lowered center of gravity, helping the trailer operate more stably and safely while minimizing vibration during operation.
The body structure is engineered for superior impact resistance and anti-deformation performance, delivering high durability and minimizing long-term repair and replacement costs.
Structural Design
The U-shaped cargo body structure with pressed reinforcing ribs enhances structural rigidity. The widened body profile effectively prevents sidewall bulging, enables faster unloading, reduces curb weight, and improves fuel and operational efficiency.
The sidewall structure incorporates seven folded reinforcement contours optimized to improve stiffness and prevent body expansion, while also allowing materials to flow out more smoothly without sticking or clogging, thereby increasing unloading efficiency. This design is especially suitable for transporting adhesive materials.
Cargo body volume: 23.3 m³.
Materials
The cargo body of the SUNHUNK Semi-Trailer Dump Truck is manufactured from K450 high-tensile steel, with 4 mm sidewalls and 5 mm floor thickness.
This material provides outstanding impact and abrasion resistance, up to four times more durable than conventional Q345B steel materials.
The pressed steel reinforcement ribs provide exceptional rigidity. The body is designed for superior impact and dent resistance, offering extremely high durability and significantly reducing repair and replacement costs over extended operation periods.
Dimensions
The internal cargo body length reaches nearly 8.5 meters.
Body profile is engineered with anti-bulging design characteristics and reinforced with additional box-section stiffeners positioned at the center of the sidewalls to improve structural strength.
Rear tailgate is positioned outside the cargo body interior, allowing easier and faster unloading.
Sidewalls are independently designed, while the chassis incorporates anti-torsion construction.
A stabilizer bar is equipped to maintain stability during body lifting and lowering operations.
The cargo body floor utilizes a structure with four auxiliary beams embracing the chassis frame, combined with 11 transverse cross-members and body stabilizer bars to ensure stable lifting and lowering while preventing body displacement.
The main I-beam chassis frame dimensions are (520/160) × 140 × (10/10) × 8 mm, providing a thick and highly rigid structure. X-shaped anti-torsion braces are installed at both the front and rear sections.
The vehicle center of gravity has been lowered by 10 cm to better match the tractor head height, improving operational stability. The fifth-wheel plate height from the ground is approximately 1,330 mm, optimized to align with the tractor’s coupling height for improved balance.
The upper sidewall reinforcement structure utilizes large box sections measuring 240 × 124 × 6 mm. The lower longitudinal reinforcement beams are constructed from box sections sized 220/160 × 74 × 6 mm. The two sidewall reinforcement pillars have widths of 300 mm and 350 mm respectively.
This box-section reinforcement structure ensures high cargo body rigidity and effectively prevents body deformation and bulging.
The rear door locking mechanism and latches utilize thick and durable cast-chain locking structures. The safety locking mechanism is raised by 20 cm, enabling faster unloading and better discharge of oversized materials.
Hydraulic Hoisting System
The SUNHUNK Semi-Trailer Dump Truck uses the renowned SUNHUNK HCTM-5JT-F202X6700Z hydraulic system (HCTM 202-5), synchronously manufactured together with the dump trailer.
The front-mounted hoist tower utilizes a synchronized SUNHUNK 224-5 hydraulic cylinder system, featuring the market’s largest hydraulic cylinder rod diameter of up to 224 mm, with maximum dumping capacity exceeding 100 tons.
The trailer is equipped with 12.00R20 steel radial tires to enhance load-bearing capability.
Customers may also choose the SUNHUNK 202-5 hoist tower configuration according to operational requirements.
The hydraulic cylinder rod diameter reaches up to 202 mm and is divided into five telescopic stages with a maximum lifting stroke of 6,700 mm.
The hydraulic cylinder is manufactured from seamless silicon-manganese steel tube grade 27 with high durability. The cylinder outer surface is specially chrome-plated to resist corrosion and wear.
A dual-layer protective ring structure is applied to provide improved impact resistance and safer, more stable operation.
The SUNHUNK hydraulic oil tank has a capacity of 228 liters and is synchronized with the hoist system.
The hydraulic tank features a flat-profile design with extended length for easier installation. The oil tank mounting base is pre-designed and supplied together with the trailer for installation convenience.
Additional hose support hangers are equipped, and hydraulic hoses are carefully wrapped with protective conduit sleeves to facilitate installation and maintenance.
Dump Semi-Trailer Structure and Components
The contact area with the fifth-wheel plate is reinforced using box-section structural members, securely welded to maximize dump trailer rigidity.
Additional reinforcement bars are welded longitudinally along the chassis frame.
The landing gear utilizes a single-leg support structure, allowing easier operation on uneven and rough terrain. Additional reinforcement braces increase landing gear load-bearing capacity up to 80 tons.
The design incorporates two auxiliary beams embracing the chassis frame to prevent displacement and maintain stability during cargo body lifting operations.
The cargo body is equipped with stabilizing braces to prevent overturning and torsional deformation during dumping operations.
Additional reinforcement stabilizer bars are installed at the leaf spring support areas.
The leaf spring pins utilize oversized pin designs made from high-tensile steel, combined with anti-wear bushings.
The dump body pivot pin adopts a full-length solid shaft structure with locking plates installed at both ends to prevent displacement. The assembly can be disassembled and replaced via bolted connections.
Heavy-duty reinforced side skirt plates are installed longitudinally along the trailer body.
Two X-shaped reinforcement braces are arranged longitudinally along the chassis frame to improve torsional rigidity and strengthen the cargo body structure.
