What is a Front-Four Rear-Eight Vehicle?
2 Answers
Front-four rear-eight is a type of heavy-duty cargo truck, featuring four wheels in the front and eight wheels in the rear. The 'front-four' refers to a dual-axle setup with four wheels in the front, while the 'rear-eight' also uses a dual-axle configuration, meaning eight driven wheels—four wheels per axle, with two wheels on each side of the axle. Generally, when referring to single or dual axles, it indicates the number of drive axles at the rear. Most large trucks employ a body-on-frame design, where the chassis includes a heavy-duty frame. This design somewhat compromises ride comfort but significantly enhances the vehicle's load-carrying capacity. Additionally, some trucks may add an extra set of rear wheels to increase vehicle length, thereby further boosting their load capacity.
I've been driving this type of front-four-rear-eight truck for several years. Simply put, it's a heavy-duty truck with four wheels in the front and eight wheels in the rear, totaling twelve wheels, designed specifically for hauling heavy loads. I often drive it on logistics routes, transporting construction materials or grain. Its load-bearing capacity is exceptional, with one truck equivalent to several smaller vehicles, and it remains stable without swaying on the highway. I remember the last time I hauled stones from the mine; encountering bumpy mountain roads, the multiple wheels helped distribute the weight, ensuring a safe arrival at the warehouse. However, this truck has higher fuel consumption, and overloading can easily wear out the tires, so extra attention must be paid to tire pressure and the suspension system during maintenance. Overall, driving it requires some skill, but it saves a lot of trouble in transportation.
