High-Load Dump Semi-Trailer (Three-Axle)

1. Product Positioning

This Mining Heavy-Load Three-Axle Dump Semi-Trailer is a high-performance transportation equipment tailored for heavy-load scenarios such as mining and infrastructure construction. With core advantages of "super load-bearing capacity, wear resistance and durability", it is suitable for efficient transportation of various bulk materials (ore, sand, muck, etc.). It is a reliable transportation partner in engineering construction and mining fields.

2. Core Configurations & Advantages

• Heavy-Duty Load-Bearing Design: The frame is made of thickened high-strength alloy steel, with crossbeam spacing reduced to 300mm. Equipped with three-axle reinforced axles (single-axle load up to 13 tons), the total load-bearing capacity is 20% higher than that of ordinary dump semi-trailers, easily coping with heavy-load working conditions.
• Wear-Resistant & Durable Structure: The inner wall of the carriage is made of 8mm thick wear-resistant steel plate, and the bottom is equipped with anti-skid and wear-resistant lining plate, which greatly improves impact resistance and wear resistance and prolongs service life. The frame surface is treated with shot blasting derusting + electrostatic spraying process, with rust prevention grade up to IP67, suitable for humid and dusty mining environments.
• Efficient Dump System: Equipped with double-acting hydraulic lifting device, the lifting angle can reach 60°, the unloading speed is fast (only 15-20 seconds for the whole process), and the residual rate is less than 1%. The hydraulic system adopts accessories from well-known brands, with excellent sealing performance and low failure rate, ensuring continuous operation efficiency.
• Safety & Stability Guarantee: Adopts widened and thickened brake shoes, combined with ABS anti-lock braking system and air brake device, the braking distance is shortened by 10%, and driving safety is higher. The optimized wheelbase design (wheelbase 5.8m+1.35m) ensures small turning radius and flexible operation, adapting to complex road conditions in mines.

3. Application Scenarios

Widely used in mining bulk material transportation (ore, raw coal), engineering infrastructure transfer (sand, muck, cement clinker), urban muck removal and other scenarios. It can be flexibly matched with various tractors, adapting to unpaved roads such as mountain roads and construction sites, and meeting the transportation needs of "heavy load, high efficiency, safety and reliability".

4. Quality & Service Guarantee

Produced in strict accordance with national heavy-duty automobile manufacturing standards, key components (axles, hydraulic systems) are all selected from first-line brands. Before leaving the factory.
