Product Overview

ZW Group 4 Axle 40CBM Bulk Transport Dump Semi Trailer is a U-type hydraulic end dump trailer for operators moving sand, coal, gravel and construction aggregates. Its stated 40-cubic-metre body volume provides a clear starting point for matching trailer capacity to a hauling route, loading equipment and material density. Four axles support the trailer’s heavy-duty configuration; the appropriate axle, suspension and braking setup should be confirmed against the intended payload and local regulations.

The rear-tipping layout is designed to simplify discharge at suitable unloading areas. A hydraulic lifting system raises the body, while the U-type body shape is intended to help bulk material flow toward the discharge end. Actual unloading time and residual material depend on the load, site conditions, hydraulic configuration and operating procedure. For safe use, unload on firm, level ground and follow the supplied operating guidance.

Designed for Bulk Haul Applications

This trailer can be specified for construction, mining and industrial logistics where loose cargo needs to move between a loading point and a designated stockpile or processing site. Typical materials include sand, coal, gravel and aggregates. Before selecting a unit, compare the body volume with the cargo’s density: a 40CBM body does not by itself define legal payload. Check the tractor-trailer combination, axle limits, route restrictions and site access in the destination market.

Configuration and Specification Checks

ZW Group lists a 4-axle layout, 40CBM cargo volume, U-type end dump body and hydraulic lifting system for this model. Published product information also describes high-strength carbon-steel construction and configuration choices for components such as suspension, tyres and hydraulic lifting. Final specifications may vary by order. Ask for a confirmed drawing and component list covering body dimensions and plate thickness, axle rating, suspension, brakes, tyres, hydraulic cylinder, tare weight, payload rating and electrical system.

Buyer note: Request written confirmation that the selected configuration meets your tractor connection, operating conditions, import requirements and applicable vehicle regulations.

Frequently Asked Questions

What materials can it transport?

Sand, coal, gravel and construction aggregates are listed applications. Confirm suitability for the material and route with the supplier.

Does 40CBM mean a 40-ton payload?

No. CBM measures volume. Payload depends on cargo density, trailer tare weight, axle ratings and legal limits.

Can I request a customized configuration?

Options may be available for components such as suspension and the hydraulic system. Ask ZW Group to confirm the exact build against your requirements.
