Tri-axle U-shape van type hydraulic rear dump semi-trailer parked on a yard, front three-quarter view

Key Benefits

What This Unit Does Well

U-shape van body with 6mm bottom plate resists wear from abrasive materials like sand and gravel
Side-opening hydraulic dump mechanism reduces loading time compared to rear-only dump designs
Leaf spring suspension on all three axles provides reliable performance on rough terrain and unpaved haul roads
12-unit 11.00R20 tyre configuration offers balanced load distribution and long tread life
CCC and ISO certification ensures compliance with export standards in major markets

Application Scenarios

Where It Is Used

Transport of crushed stone from a quarry to a road construction site on unsealed access roads
Bulk sand hauling between a riverbed and a concrete batching plant in a remote mining zone
Rock transport for dam or embankment construction where dump height and ground clearance matter
Long-haul hauls between a mine and a processing plant where payload capacity is the main constraint

Fit

Who It Is For

Contractors managing large-scale earthmoving and aggregate transport projects
Mining operations requiring high-capacity dump trailers for daily hauls
Construction firms sourcing cost-effective trailers for site-to-site material movement
Fleet operators standardizing on a single trailer type with shared spare parts across multiple sites

Buyer Pain

Problems It Solves

High transport cost due to low payload per trailer run on long hauls
Frequent trailer breakdowns from thin or weak body plates under abrasive cargo
Slow unloading caused by rear-only dump systems that require repositioning
Inconsistent axle load distribution leading to overloading and fines in border inspections
Lack of local spare parts for foreign-branded trailers with no local service network

Honest Comparison

How It Compares With the Alternatives

Rear-only dump trailer	Side dump allows faster unloading without repositioning, but requires more ground clearance and space for operation
2-axle trailer	3-axle design supports higher payload and better weight distribution on rough roads, but costs more in fuel and maintenance

Use Guide

Using It Well

Check hydraulic fluid level before each shift and replace if contaminated
Avoid dumping on soft ground to prevent landing gear sinking and axle misalignment
