Why Choose This Dump Semi-Trailer

Q345 High-Tensile Steel Box

Superior strength-to-weight ratio versus standard Q235. The box withstands heavy rock, ore, and demolition debris without deformation.

HYVA Hydraulic System

Genuine HYVA (Netherlands) cylinder and hydraulic kit — industry gold standard for dump applications. Fast, reliable tipping with quick-connect coupling.

FUWA 16T Axles × 3

Three FUWA 16-tonne axles deliver a combined 48-tonne axle capacity, comfortably handling the 40-tonne payload with reserve margin for rough terrain.

Integrated Double-Shaft Hinge

The box tilts on an integrated double-shaft hinge — distributes load evenly during tipping, reduces stress on the chassis, and improves stability on uneven ground.

21.5 m³ Rectangle Box

8.5 × 2.3 × 1.1m internal — optimized for sand, gravel, coal, ore, and demolition waste. Rectangle shape maximizes load volume for every trip.

Box dimensions, material thickness, axle brand (BPW optional), suspension type, tire brand, color, and accessories — all customizable to your market requirements.
