Самосвальный полуприцеп U Type 6 Axle Dump Semi Trailer

ZW Group U Type 6‑axle 40 ton dump semi‑trailer for sand and coal hauling — heavy‑duty U‑type chassis, HYVA hydraulic tipping, high‑strength steel cargo box; reliable export‑ready solution with 20–30 day delivery.

Product Descriptio

ZW Group’s U Type 6‑axle 40 ton dump semi‑trailer is engineered for demanding sand and coal transport duties. This heavy‑duty dump semi trailer combines a reinforced U‑type chassis, thick high‑strength carbon steel cargo box, and a HYVA hydraulic tipping system to deliver reliable performance, efficient unloading and long service life in harsh operating environments.

Core Construction & Durability

The cargo box uses abrasion‑resistant carbon steel with substantial plate thickness—designed to resist wear from sand, gravel and coal. The main I‑beam frame is constructed from Q345 steel with a beam height of 500 mm and multi‑layer plates for superior bending and torsional rigidity. Reinforced cross members and the U‑type structure prevent deformation under full load, ensuring consistent stability on uneven terrain.

Payload, Stability & Handling

Configured to carry a nominal 40+ ton working payload, this 6 axle dump trailer improves weight distribution across axles to reduce road wear and enhance handling. The standard 10‑leaf spring mechanical suspension delivers durability on rough sites, while an optional air suspension is available for clients seeking smoother transport and deck height adjustment.

Hydraulic Tipping System

A HYVA hydraulic cylinder powers the rear tipping mechanism for smooth, reliable lifting and steep dump angles that enable rapid, complete discharge of sand, coal, gravel or ore. All hydraulic components are pressure‑tested during assembly and final inspection to minimize downtime in the field.

Axles, Wheels & Braking

ZW brand 13‑ton axles provide dependable support for heavy loads. The trailer is fitted with heavy‑duty 12R22.5 tires and matching steel rims sized for the wheel configuration. Dual‑line pneumatic braking with multiple air chambers per axle is standard, and ABS is available as an optional safety enhancement for steep descents or high‑speed routes.

Corrosion Protection & Finish

Chassis components are shot‑blasted to remove rust and scale before painting. A coating system of one anticorrosive primer followed by two coats of urethane finish in customer‑specified color ensures long‑term protection and a professional appearance for export markets.

Ordering & Customization

Clients may specify paint color, axle brand options, ABS inclusion, air suspension upgrades and kingpin size. Contact ZW Group sales for a tailored quotation, technical drawings and export documentation to match project needs.
