Used HOWO 6x4 vs 8x4 Dump Trucks: Which Configuration Should You Buy?

What the axle numbers mean
A 6x4 HOWO dump truck has three axles, with two driven rear axles. An 8x4 generally has four axles, including two steering front axles and two driven rear axles. This change affects wheelbase, turning circle, body layout, axle-load distribution and the types of sites the truck can enter.
Choosing for the route
A 6x4 can be easier to position on restricted construction sites and short shuttle routes. An 8x4 may suit operations using a longer tipper body and routes where the extra axle is beneficial. Narrow site entrances, soft ground, gradients and turning space can make a nominally larger truck less productive. Always assess the complete route, not just the loading point.
Where specification differences appear
Compare engine power and torque, gearbox ratios, axle capacities, suspension, tire size and the internal body length, width and depth. Body volume is not legal payload. Material density, gross vehicle weight, axle limits and braking capability determine safe loading. A wet-soil load and a light aggregate load can occupy similar space but weigh very differently.
Inspect both layouts before buying
Used 8x4 units require particular attention to the additional steering axle, steering linkages and front suspension. On both types, inspect rear axle housings, differential locks if fitted, frame rails and the lifting gear. Request a road test and a demonstration of the dump system. The right answer is the truck whose dimensions and running gear suit your actual work.
