Product Description

The Haolong 4x2 dump truck is engineered for operators who need the load capacity of an 18-ton tipper without paying for, or maneuvering, a 6X4 or 8X4 rig. Built on the Tri-Ring Haolong medium-duty platform — the same chassis family that anchors more than 50,000 vehicles delivered worldwide each year — this truck combines a 160-245 PS Yuchai diesel drivetrain, a heavy-duty ladder frame, and a hydraulically lifted cargo body in a compact 4X2 footprint.

With a body width of 2,140-2,240 mm and a container length of 3,800-5,300 mm, the Haolong 4x2 slips through narrow urban access roads, tight construction-site gates, and forest-rural routes that defeat wider 6X4 competitors, while still delivering 10,000-11,000 kg of payload per load. The result is a tipper that works on the small-payload, high-frequency jobs that fleet owners actually run most days — aggregate delivery to ready-mix plants, debris removal on inner-city builds, and short-cycle quarry-to-crusher hauls.

Features and Highlights

• Proven 18-ton platform: Same Tri-Ring Haolong ladder frame used across mining, municipal, and logistics fleets in 50+ export markets.

• Yuchai diesel powertrain: 4.3 – 6.2L YC-series engine, 160 – 245 PS (118 – 180 kW), Euro V and Euro VI compliant depending on market.

• Compact 4X2 footprint: Shorter wheelbase and tighter turning radius than 6X4 rivals — ideal for confined sites.

• Front-lift hydraulic dump: Single-ram front-lifting cylinder delivers a 45°-50° tip angle for clean load ejection.

• Dual-circuit air brakes with ABS: Stops a fully loaded 18-ton truck predictably on grades and in wet conditions.

• Heavy-duty steel bed: Q235 carbon-steel floor with reinforced cross members, designed for crushed stone, sand, demolition debris, and ore.

• Operator-focused cab: Bluetooth radio, multifunction steering wheel, electric windows, central locking, and factory air conditioning.

• Multi-market certification: Available with ISO 9000, CCC, CE, and country-specific packages for Africa, the Middle East, and South America.

Powertrain and Chassis

The Haolong 4x2 is offered with the Yuchai YC4E and YC6L diesel families, displacing 4.3 to 6.2 litres and producing 160 to 245 PS (118 to 180 kW) of peak power. These engines are paired with a manual 8-speed gearbox, a 5,000 kg-rated front axle, and a 10,000 kg-rated single-reduction rear axle. Maximum speed is electronically limited to 88 km/h, which is the legal ceiling in most construction-truck markets and is fast enough for short intercity transfers between adjacent job sites.

The chassis is a straight ladder frame, 250 × 80 × (6.5 + 5) mm dual-channel steel, a proven Tri-Ring specification that survives more than 200,000 km of full-load operation. Suspension uses 9-leaf front springs and 10+8-leaf rear springs, tuned to absorb the shock of an 18-ton GVW on unpaved haul roads. The 4X2 driveline keeps unladen weight low (around 7,200 kg), so every kilogram of payload capacity is available for the cargo, not the chassis.

Cargo Body and Dump Mechanism

The dump body is sized to match the truck's working envelope, not to chase headline payload numbers. Body width spans 2,140 to 2,240 mm, container length spans 3,800 to 5,300 mm, and side-wall height is configurable from 600 to 1,500 mm — letting buyers choose between a low-profile aggregate body and a higher-volume muck or demolition body. The cargo box is built from Q235 carbon-steel plate: 3 mm floor, 2 mm sides, with internal cross ribs to prevent flexing under impact loads from excavator-shovel loading.

A single front-mounted telescopic ram lifts the body to a 45°-50° tip angle, ejecting clay, sand, gravel, or broken concrete in 15 to 25 seconds. The hoist is governed by a double-counterbalance valve, so the bed cannot free-fall even if a hydraulic line is damaged mid-lift. Optional fittings include a tarpaulin cover, a tailgate with chute control, and a coal-ore liner for high-impact loads.

Hydraulic and Electrical System

The hoist circuit is driven by a gear-type hydraulic pump matched to a manual control valve inside the cab. A single lever raises and lowers the body; the operator sees a clear visual indicator at full lift and full down. The hydraulic tank is sized for sustained operation in ambient temperatures from -20°C to +50°C, with optional high-temperature oil for Middle East deployments and low-temperature hydraulic fluid for cold-climate sites.

The 24V electrical system uses two 100 Ah maintenance-free batteries, a 28V 80A alternator, and a CAN-bus-friendly instrument cluster that displays engine speed, vehicle speed, oil pressure, coolant temperature, fuel level, and (on request) load-weight readings. All lighting is LED: headlamps, work lamps at the rear of the body, side marker lamps, and daytime running lights. Pre-wired harness provisions are included for telematics, fleet-management GPS, and reverse-camera systems.

Cab and Operator Comfort

The Haolong 4x2 uses the proven Tri-Ring T-series cab, a medium-height forward-control design that gives the driver a clear view of the load, the road, and the dump body during tipping. The cab is 2,240 mm wide — enough for three adult occupants — and is built with a reinforced steel safety frame that meets ECE R29 cab-strength requirements.

Standard comfort equipment is unusual for a truck in this class and includes:

• Bluetooth-enabled radio with USB and auxiliary input

• Multifunction steering wheel for audio, phone, and cruise control

• Electric windows and central door locking

• Factory-fitted air conditioning with a high-capacity compressor

• Adjustable suspension driver's seat with integrated headrest

• Flat passenger bench with fold-down centre backrest

• Dual sun visors and overhead storage

The result is a workspace that drivers can stay in for 10 to 12 hours without the fatigue that cuts productivity on lesser-equipped rigs.

Braking, Tires, and Safety

An 18-ton truck that spends its life on loose quarry surfaces and wet urban streets needs serious stopping power. The Haolong 4x2 runs a dual-circuit air-over-mechanical brake system on all wheels, with an ABS anti-lock controller as standard. The parking brake is spring-applied and air-released, a fail-safe design that engages automatically if system pressure is lost. An exhaust brake is fitted to the Yuchai engine, providing supplementary deceleration on long downgrades without consuming the service brakes.

Tires are 10.00R20-18PR mining-pattern steel-belted radials, fitted to six wheels plus a full-size spare. The aggressive tread pattern grips on mud, sand, and broken rock, while the 18PR rating supports the 18-ton GVW at recommended inflation pressures. A tire-pressure monitoring system is available as an option for fleets that run on long-distance transfer routes between quarries.

Typical Applications

The Haolong 4x2 dump truck is the workhorse choice for a specific set of jobs — the ones where a 6X4 is too long, a 4X4 is too slow on the highway, and a light-duty tipper is too small for the load. The most common deployments include:

• Construction site haulage: moving sand, gravel, and crushed stone from on-site stockpiles to batching plants and formwork locations.

• Quarry-to-crusher transfer: short-cycle aggregate haulage within a single quarry or between adjacent sites.

• Road and bridge building: delivering fill material, base course, and asphalt millings to paving crews on highway projects.

• Demolition and muck removal: clearing broken concrete, bricks, and earth from inner-city redevelopment sites.

• Municipal logistics: winter road grit, summer construction waste, and storm-debris collection.

• Mine support: hauling supplies, waste rock, and consumables between camps and active pits on large mine leases.

• Agricultural bulk: grain, sugar beet, and fertilizer movement during seasonal peaks.
