Used HOWO TX 6x4 U-Type Dump Truck for Heavy-Duty Hauling

The Used HOWO TX 6x4 U-Type Dump Truck is built for demanding material transport where strong traction, efficient unloading and durable construction are essential. With a three-axle chassis, tandem rear drive axles and a hydraulic rear-tipping body, this truck is well suited to construction sites, mines, quarries, road projects and bulk-material transport.

Compared with a conventional square dump body, the U-shaped body has a smoother inner profile. Therefore, sand, soil, gravel and similar materials can slide toward the rear more easily during unloading. At the same time, the curved structure reduces sharp internal corners where material can collect.

For contractors, equipment dealers and fleet operators looking for a practical second-hand heavy-duty dump truck, the HOWO TX platform provides a proven configuration with broad parts availability and several powertrain options.

U-Type Dump Body for Faster Unloading

The most visible feature of this truck is its reinforced U-shaped cargo body.

Instead of using a flat floor with sharp side corners, the U-body uses a curved lower section. As a result, loose material moves more smoothly when the hydraulic cylinder raises the body.

This design is especially useful for:

• Sand and gravel
• Soil and earth
• Crushed stone
• Construction waste
• Mining material
• Clay and mixed aggregate

The curved profile can also distribute loading forces through the body structure instead of concentrating them at conventional square corners.

Typical HOWO TX 6×4 dump trucks are offered with approximately 18–28 m³ body capacities, depending on wheelbase and application.

6x4 Drivetrain for Difficult Job Sites

A 6×4 dump truck uses one steering axle and two driven rear axles. This gives the truck strong traction when working on gravel roads, construction sites, quarry roads and other uneven surfaces.

Published HOWO TX specifications commonly use a heavy-duty front axle together with dual 16-ton-class rear axles. Heavy multi-leaf suspension is also widely used for engineering transport applications.

Therefore, the chassis is suitable for repeated loading and unloading cycles while carrying dense bulk material.

Strong Diesel Power for Heavy Loads

HOWO TX 6×4 dump trucks are available with several diesel engine configurations.

Depending on production year and market, published engine outputs range from approximately 266 to 440 PS. A common 400 HP configuration uses a Weichai WP10H-series diesel engine, while higher-power versions can use SINOTRUK MAN-series engines.

For used trucks, the actual engine should always be checked individually because engine type and emission configuration can differ between batches.

A high-torque diesel engine helps the truck start under load, climb site roads and maintain practical transport efficiency during short- and medium-distance hauling.

Reference Specifications

Published configurations vary by model year and destination market; for example, one HOWO TX 6×4 specification lists a 4325+1350 mm wheelbase, 5.6–6.3 m cargo-body length and maximum speed around 85 km/h.

Hydraulic Tipping System

Efficient unloading is a major requirement for a dump truck.

The hydraulic tipping system raises the complete cargo body and allows material to discharge from the rear. This reduces unloading time and supports frequent transport cycles.

Before a used truck is prepared for sale, key hydraulic components can be checked, including the lifting cylinder, hydraulic lines, pump connections, tipping hinges and tailgate locking points.

This is particularly important for trucks that will return to intensive quarry or construction work.

Reinforced Chassis and Suspension

Dump trucks experience repeated vertical and torsional loads. Therefore, chassis condition is an important purchasing factor.

The HOWO TX platform uses a heavy-duty frame with multi-leaf suspension and tandem rear axles. These components support loaded operation while maintaining stability on uneven roads.

For a used unit, inspection should focus on:

• Main frame rails
• Cross members
• Rear suspension
• Leaf springs
• Axle housings
• Propeller shafts
• Body mounting points
• Hydraulic lifting structure

Checking these areas helps fleet buyers evaluate whether the truck is suitable for continued heavy-duty service.

Suitable Applications

The used HOWO TX 6x4 U-body dump truck is suitable for a wide range of commercial and engineering operations.

Typical applications include construction earthmoving, quarry transport, mining haulage, road building, aggregate delivery, sand transport, demolition waste removal and infrastructure projects.

Its U-type body is particularly practical where quick discharge of loose or slightly sticky material is required.

Used Truck Supply for B2B Buyers

For dealers, contractors and fleet operators, used trucks can be selected according to required horsepower, body size, production year, destination and working conditions.

Before shipment, buyers can request current vehicle photos, engine-running videos, chassis details and basic inspection information. Trucks can also be prepared for container, flat-rack or Ro-Ro shipping depending on vehicle size and destination.

Since used trucks vary from unit to unit, final specifications should always be based on the actual chassis number and vehicle nameplate.

FAQ

What truck is shown in the pictures?
It is a SINOTRUK HOWO TX-style 6×4 heavy-duty dump truck with a U-type rear-tipping body.

Why choose a U-type dump body?
The curved inner structure helps bulk materials discharge smoothly and reduces areas where soil or aggregate can remain trapped.

How many wheels does a HOWO 6x4 dump truck have?
It is commonly marketed as a 10-wheel dump truck, using one front axle and two rear drive axles with dual rear tires.

What horsepower is available?
HOWO TX 6×4 configurations are available across a broad power range. Common heavy-duty versions include approximately 371, 400, 430 and 440 HP configurations.

Can the exact specifications be confirmed before ordering?
Yes. Engine model, year, mileage, body dimensions, tires and other details should be confirmed for the specific used truck before purchase.
