4-Axle Rear Dump Semi-Trailer

Product Introduction

This product is a 4-axle rear-dump semi-trailer constructed from high-strength steel. The vehicle dimensions are customizable (e.g., 9,000–12,000 mm x 3,000 mm x 1,750 mm), with a maximum payload capacity exceeding 30 tons.
It utilizes a hydraulic lifting system for rear-dump unloading, offering high efficiency and a compact operational footprint. It is ideal for transporting bulk materials—such as sand, gravel, ore, and coal—in settings including mines, quarries, and construction sites.
The 4-axle configuration effectively distributes ground pressure, enhancing driving stability and braking safety. This product is primarily targeted at semi-trailer distributors in overseas markets such as Africa, Saudi Arabia, and the UAE.

Key Features

• 4-Axle Load-Bearing Design: Standard configuration features 4 axles with optional single-axle load capacities of 13 or 16 tons, providing superior total load-bearing capacity; distributes ground pressure to enhance driving stability and unloading safety; complies with overseas regulatory requirements for heavy-duty transport.
• Rear-Tipping Unloading: Hydraulic lifting system enables the cargo box to tip backward for unloading; requires minimal operating space, making it ideal for confined mining areas and construction sites; simple operation and rapid unloading.
• High-Capacity Cargo Box: Cargo volume options range from 42 m³ to 55 m³; enables large-volume transport per trip, reducing unit transport costs and improving operational efficiency.
• High-Strength, Wear-Resistant Floor: 4mm wear-resistant steel floor plate; impact- and wear-resistant, suitable for loading and unloading abrasive materials like ore, ensuring a long service life.
• Customizable Axle Brands: Options include renowned brands such as FUWA and BPW; meets diverse market preferences regarding axle brands and enhances product competitiveness.
• JOST Kingpin: 2-inch or 3.5-inch options; ensures a reliable connection and is compatible with mainstream tractor units.
