俗称翻斗挂车，U 型 / 矩形货箱，液压举升，后翻卸料，拉砂石、土方、矿石、渣土，加纳、西非基建矿山热门车型
✅ General Description of Core Structure (3/4/6 Bridge Common Foundation)
Cargo box style
U-shaped box (preferred in Africa): inner wall arc, soil clay non-stick box, clean discharge; baseplate 8mm, side plate 6mm wear-resistant high-strength steel
Rectangular box: square box, larger volume, suitable for gravel and ore; easy to accumulate materials at the corners
Lifting system
: HYVA multi-section front hydraulic cylinder, cab remote control lifting, unloading for 2 to 3 minutes; with anti-tipping limit, hydraulic lockgirder
: T700 high-strength steel, thickened upper and lower wings, automatic submerged arc welding; reinforced ribs are added for the heavy-duty versionsuspension
Mechanical leaf spring suspension (standard in Africa, simple maintenance, rotten road resistance); optional air suspension and lifting bridge (empty car can lift the bridge, saving tires and fuel)brake
: Dual circuit air brake, ABS optional; 24V circuit, LED tail lightPins & outriggers
JOST 2 inch/3.5 inch traction pin, 28 tons linkage outriggersoptional accessories
Automatic electric tarpaulin, toolbox, spare tire frame, non-slip and wear-resistant baseplate
✅ Comparison of bridge type parameters
3 Axle Dump Trailer
Load capacity: 35 - 45 tons
Volume: 28 - 35 CBM
Axle: 313-ton Fuhua Bridge
Weight: about 9 to 10.5 tons
Applicable scenarios: ordinary construction site sand and gravel, earthwork, highway + mild unpaved road;
West Africa's largest volume base modelAdvantages: light weight, low fuel consumption, cheap accessories, flexible turnover;
Short board: mine heavy load, super large square volume is not recommended
4 Axle Dump Trailer
Load capacity: 50-60 tons
Volume: 35 - 42 CBM
Axle: 413/16 ton heavy-duty bridge
Weight: Approximately 11-13 tons
Applicable scenarios: quarries, short-distance transshipment of mines, large-scale infrastructure projects; dirt roads, crushed gravel roads
Advantages: The bearing capacity is greatly improved, the tire load is scattered, and it is not easy to trap.
Weaknesses: The body is heavier, and the fuel consumption for long-distance road transportation is higher than that of 3 bridges
6 Axle Dump Trailer
Load capacity: 70-80 tons
Volume: 42 - 48 CBM (45 square meters are commonly used for large orders in Ghana mines)
Axle: 613 tons.
Lifting bridge
(Empty car lifts part of the axle to reduce tire wear)Weight: Approximately 15 to 17 tons
Applicable scenarios: large mines, large earthworks, oversized tonnage and heavy load;
Advantages: the strongest load-bearing, axle load dispersion, good load stability, suitable for continuous high-intensity mining operations;
Shortboard: long body, large turning radius, higher procurement cost
Uses and Application Scenarios of Rear Dump Tipper Trailer
The dump semi-trailer relies on the hydraulic cylinder to lift the cargo box and realize automatic backloading and unloading without manual shoveling. It is the main bulk material transportation trailer in the field of mines and infrastructure in Africa. 3/4/6 bridge is selected according to the load and working conditions.
First, the core purpose
Earthwork transfer
: Red soil, earthwork, clay, backfill excavation and short-distance backhaul, infrastructure road construction, site leveling, dam engineering. U-shaped cargo boxes are not easy to stick to soil, and unloading is clean.Sand and gravel aggregate transportation
: river sand, gravel, gravel, mixing station supply, building materials site.ore mining transshipment
: Iron ore, limestone, gold ore/quarry gross ore. 4 bridges and 6 bridges are preferred for unloading in heavy-duty working conditions, and the bearing capacity is stronger.Construction waste and muck removal
Site waste, crushed stone.Loose materials such as coal and grain
: Coal mine short-distance transshipment, bulk grain (need to add a sealed tarpaulin).
✅ 一句话概括：专门运输各类散装颗粒、块状、泥土类物料，自动举升卸料，大幅节省卸货人工与时间
Second, the bridge type application scenario
3-Bridge dump semi-trailer
Suitable for medium loads, highways, and light dirt roads.
Uses: small and medium-sized construction site earthwork, sand and gravel, municipal engineering, mixing station sand and gravel distribution.
Advantages: light weight, flexible, cheap accessories, and the largest shipments in the African market.
4-Bridge dump semi-trailer
Heavy-duty short-haul, quarries, medium-sized mines, and large-scale infrastructure projects.
Uses: gravel, ore, a large amount of red clay transport, pothole construction site road.
Advantages: The axle load is scattered, and it is not easy to burst or trap, taking into account both load and mobility.
6-Bridge dump semi-trailer
Super large tonnage and heavy load, large mines, large-scale earthmoving projects.
Uses: High-yield mine ore, a large amount of earth and stone, continuous high-intensity working. many configurations
Lifting bridge
Empty cars lift the axle to reduce tire wear.Advantages: The strongest bearing capacity, suitable for long-term heavy loads; the disadvantage is that the body is long and the turning space is required.
III. Applicable regions & working conditions (focus on West Africa/Ghana)
Pavement: dirt road, gravel road, mining area rotten road mostly, leaf spring suspension more durable, easy maintenance.
Climate: high temperature and rainy, sandblasting + thick paint anti-rust, optional electric tarpaulin rainproof.
Transportation distance:
Mainly short-term bad luck
(Inside the mining area, between construction sites), not suitable for long-distance trunk lines.
IV. Unsuitable scenarios
❌ Large solid goods such as pallets, steel, and equipment cannot be transported (front-end flatbed trailers are used for this type).
❌ Not suitable for precision, fragile, liquid materials
❌ Long-distance high-speed trunk transportation (large weight, high fuel consumption)
