8×8 means that all four axles of the vehicle are drive axles, and all 8 wheels provide driving force. It is a heavy-duty all-wheel drive special chassis. Compared with 8×4 (only the rear two axles are driven), 6×6, and 4×4, the driving capacity, off-road load-bearing, and passability in complex road conditions have been greatly upgraded. It is mostly used in heavy-duty engineering machinery transport vehicles, special operation vehicles, large excavator boards, mining dumps, and special chassis for carrying large items.

Four sets of heavy-duty through-type drive axles are equipped with differential locks, wheel-side reduction structures, and full-time/part-time all-wheel drive switching; the transmission shaft is thickened and thickened, and the transfer case has a large carrying capacity and can realize multi-speed power distribution. The four wheels are driven simultaneously, the differential is locked when slipping, and the single wheel is suspended in the air and still has strong traction. The beam load-bearing structure adopts double/three-layer thickened high-strength manganese steel beams, which are integrally stamped and welded. The longitudinal beams are widened and heightened, and the cross beams are intensively reinforced to resist distortion, heavy pressure, and bumps and impacts. The chassis carrying capacity is much higher than that of a semi-drive chassis of the same level, and it will not deform or crack under heavy load. It is equipped with a high-horsepower heavy-duty diesel engine, with the horsepower generally ranging from 420 to 600 horses. It is matched with a Fast high-torque manual transmission or an automatic gearbox, with high and low-speed auxiliary boxes. The low-speed torque is extremely explosive, and it can start well on steep slopes, muddy and gravel roads. Multiple thickened heavy-duty leaf springs + thickened shock absorbers, some high-end models are equipped with hydro-pneumatic suspension; large-size heavy-duty mining vacuum tires/wire tires, the tire pressure is adapted to harsh road surfaces; the wheelbase is widened to improve the vehicle's driving stability. Exhaust brake and retarder provide stable braking on heavy loads and long downhill slopes; multi-circuit air supply to the entire vehicle ensures fast braking response and higher safety factor for heavy-load transportation.

Super all-wheel drive off-road capability, eight-wheel all-wheel drive, full of grip, easy to pass through muddy construction sites, soft soil roads, steep mine slopes, potholes, rain and snow icy roads, and sites that ordinary two-wheel drive or rear eight-wheel vehicles cannot enter, the 8×8 chassis can go directly to the work site. The four axles with extreme heavy-load carrying capacity share the load synchronously, and the compliance carrying tonnage far exceeds that of the 8×4 chassis. It is often used to customize large-tonnage excavator boards and large flatbed trucks, and can carry 35–60-ton large excavators, rotary drilling rigs, crawler cranes, and heavy mining equipment. Durable and resistant to harsh working conditions, the transmission, axles, and girders are all strengthened to heavy-duty specifications. The failure rate is low under long-term high-intensity bumps and full-load impacts. It can be used stably in mines, field infrastructure, and remote construction sites for a long time, and the maintenance cycle is long. It has strong site adaptability. It can drive smoothly on long-distance national highways and high-speeds, and can also be used for off-road transport in unpaved fields. It can take into account long-distance transportation and on-site transport. One machine has multiple uses.

Mainstream modification application scenarios: engineering machinery flat plate (excavator plate), customized low flat plate to pull 30-60 tons of large excavators, rotary excavations, road rollers, and tunnel boring machines; mining-specific Dump truck, pulling ore and muck in underground and open-pit mines; large special transport vehicles: heavy equipment, transformers, and wind power accessories transfer; special operation vehicles, heavy-duty crane chassis, rescue vehicles, oil field workover trucks, and radar shelter chassis.

8×8 is a high-end heavy-duty special chassis with a higher cost than 8×4 and 6×6. However, it is unrivaled in off-road, load-carrying, and passability. It is suitable for fleets and leasing companies that often travel on bad roads, haul oversized tonnage equipment, and operate in high-frequency fields in mines. It is the top chassis choice for heavy-duty off-road transportation. 8×8 all-wheel drive heavy-duty chassis, four axles and eight-wheel all-drive, high horsepower and torque, thickened three-layer girder, with differential lock for full off-road capability; strong load-bearing capacity, non-slip on bad roads, easy to climb steep slopes, can be modified to large-tonnage excavator flatbed, mining dump, large transport vehicle, the first choice for field heavy-duty transfer of the top chassis.
