What is the capacity of a front-four rear-eight dump truck?
4 Answers
A front-four rear-eight dump truck can carry approximately 30 cubic meters, with the current standard generally being 25-30 cubic meters. Below is an introduction to front-four rear-eight trucks: 1. Purpose: The maximum load capacity of a front-four rear-eight truck is 31 tons. It is a cargo truck with a front steering axle consisting of two axles and four wheels, and a rear drive axle with two axles, each with dual wheels, totaling eight wheels. Common types of front-four rear-eight trucks include dump trucks, heavy-duty trucks, and trailer trucks. Due to their high load capacity, they are often used for long-distance transportation. 2. Overloading: Driving a truck with a load exceeding 30% of the approved weight will result in a 6-point penalty, while exceeding the approved weight by less than 30% will result in a 3-point penalty. Commercial vehicles exceeding the approved weight will be fined, and those exceeding the approved weight by 30% will also face fines.
After driving for so many years, the capacity of a front four rear eight dump truck is generally around 18 to 24 cubic meters, depending on the size of the cargo box. The standard model has a cargo box length of about 5.6 meters, width of 2.3 meters, and height of 1.5 meters, which multiplies to roughly 20 cubic meters. When actually loading materials like sand or gravel, you might load one or two cubic meters less due to compaction or shape. I always emphasize measuring the internal dimensions of the cargo box before purchasing—don’t blindly trust advertisements. Also, avoid overloading during operation; overloading not only results in hefty fines but is also dangerous and can easily cause tire blowouts. For maintenance, the hydraulic system is key—check for oil leaks monthly, as wear and tear accelerate with frequent use on construction sites. Safety first: equip a good tire pressure monitoring system to avoid roadside troubles and improve efficiency. In short, capacity isn’t a fixed value; recording your own experience is more accurate, and beginners should seek advice from veteran drivers.
Common capacity issues with these vehicles: most 4-axle dump trucks (front 4 rear 8 configuration) have a capacity between 19 to 22 cubic meters. Differences in carriage plate thickness or internal design can affect actual loading volume - some trucks have uneven inner walls or poorly designed locking grooves. When we measure capacity during repairs, 20 cubic meters is the average benchmark. Frequent customer complaints about incomplete loading usually stem from carriage deformation or poor sealing. I recommend owners conduct a fixed capacity test during annual inspections using cement blocks for verification. Maintenance should focus on hydraulic pumps and suspension systems, as failure in these components makes dumping difficult. Safety-wise, overloading increases tire blowout risks - tire pressure monitoring is essential to reduce repair costs.
Planning to buy a 4-axle 8-wheel dump truck, but stuck on capacity doubts. Online says 18 to 25 cubic meters, so I'll measure the cargo box at the dealer: 5.8m long, 2.4m wide, 1.4m high holds about 20 cubic meters. Actual test loading with sand/soil is needed to confirm, worried about size deception. Cost comparison: Bigger capacity saves fuel with fewer trips but strains the engine; smaller capacity is agile for short hauls. Must consider eco-friendliness too – efficient models reduce emissions and cut maintenance costs. Researching for balance, will consult experienced owners before finalizing to avoid wrong purchase affecting business.
