Tri axle dump trucks are a critical part of the commercial vehicle industry, especially in construction, mining, and heavy materials transportation. As a leading commercial vehicle supplier, KeyChain Venture Co., Ltd. understands that knowing the weight of tri axle dump trucks is essential for optimizing transport efficiency, complying with road regulations, and ensuring safety. This comprehensive article explores everything you need to know about tri axle dump truck weights, including their specifications, factors influencing weight, operational insights, and practical tips for use.

A tri axle dump truck is a heavy-duty vehicle equipped with one front steering axle and three rear axles. This configuration increases the load capacity and improves weight distribution on roads, allowing the truck to carry heavier payloads safely. The tri axle setup balances the load more efficiently than single or tandem axle trucks, making it ideal for hauling loose materials such as gravel, sand, asphalt, and construction debris.
Tri axle dump trucks are widely used in numerous sectors due to their durability and versatility. They come in various sizes and chassis models, often equipped with strong engines and heavy-duty suspension systems to handle tough transport tasks.
The weight of a tri axle dump truck depends on different factors, including its size, the materials used in construction, payload capacity, and optional equipment. Generally, these trucks weigh:
- Empty weight: 25,000 to 35,000 pounds (11,340 to 15,875 kilograms).
- Loaded weight: 52,000 to 68,000 pounds (23,587 to 30,844 kilograms), depending on the amount and type of material hauled.
This weight range positions tri axle dump trucks between tandem axle and larger 18-wheeler dump trucks, offering a balanced capability for heavy-duty hauling on various terrains and roadways.
Tri axle dump trucks vary in size depending on the chassis and body type. Common body lengths are between 16 to 18 feet, with a width close to 8 feet and a height around 10.5 feet with sideboards. These dimensions allow for hauling 15 to 19 cubic yards of material, adapting to different construction and industrial needs.
Steel is the most commonly used material for dump truck bodies, providing high durability and resistance to wear and tear from heavy loads. Steel-bodied tri axle dump trucks tend to have heavier empty weights but longer lifespan under tough operational conditions.
Aluminum bodies provide a lighter alternative, saving around 1,000 to 1,500 pounds of empty weight compared to steel. Although aluminum dump trucks might not support as heavy loads as steel, their fuel efficiency and corrosion resistance are advantageous, especially for vehicles operating in wet or corrosive environments.
The three rear axles are fundamental in spreading the truck's weight evenly. This helps increase the gross vehicle weight rating (GVWR) and distribute the load to minimize road damage and wear. Many tri axle dump trucks are equipped with a liftable or tag axle, which can be raised when the truck is empty or lightly loaded. This not only reduces tire wear but also improves fuel efficiency and maneuverability.
Axle suspension types also affect weight. Air ride suspensions, while offering better ride quality and load protection, add some weight compared to mechanical spring suspensions.
The payload directly impacts a tri axle dump truck's loaded weight. With capacities ranging from 26 to 30 tons, these trucks are suited for various materials with different densities:
- Sand generally weighs about 100 pounds per cubic foot.
- Gravel ranges from 95 to 105 pounds per cubic foot.
- Asphalt weighs approximately 145 pounds per cubic foot.
- Construction debris and riprap vary widely depending on composition.
Given these densities, a tri axle dump truck filled to capacity can have a wide range of loaded weights, making accurate load estimation and proper weight distribution critical.
Optional equipment such as hoists, toolboxes, additional fuel tanks, tarps, snow plows, or lighting can add hundreds or even thousands of pounds to the truck's gross weight. When trucks are customized for specific jobs (such as snow removal or off-road construction), these add-ons increase the empty weight, which must be accounted for in load calculations.

Adherence to legal weight limits is crucial for tri axle dump trucks to avoid fines and maintain road safety. Weight limits differ by jurisdiction but generally include maximum gross vehicle weight and specific axle load limits. For example, the federal gross vehicle weight limit on interstate highways is typically 80,000 pounds, but tri axle dump trucks usually operate within a range of 54,000 to 70,000 pounds GVWR depending on state-specific regulations.
Operators must regularly verify axle weights using portable or fixed weigh stations and adjust loads or routes accordingly.
Proper load distribution across the three axles and within the dump body prevents uneven tire wear, reduces stress on the suspension, and maintains vehicle handling. Safety considerations include securing the load to prevent shifting during transport, which can affect weight balance and control.
Fuel consumption increases with vehicle weight. Lighter aluminum bodies and liftable axles help optimize fuel economy. Regular maintenance of tires, brakes, suspension, and hydraulic systems enhances safety and performance, especially when hauling near maximum payloads.
Due to their balance of size and capacity, tri axle dump trucks are commonly used in:
- Road construction for hauling aggregated materials.
- Landscaping and excavation projects.
- Municipal services including snow removal and debris hauling.
- Mining and quarrying operations.
- Heavy equipment and materials transport at industrial sites.
Their adaptability and load capacity make tri axle dump trucks a valuable asset for many sectors needing efficient bulk materials transport.
Tri axle dump trucks are versatile and robust commercial vehicles designed to optimize payload capacity while adhering to road safety and legal standards. Their typical empty weight ranges from 25,000 to 35,000 pounds, with loaded weights reaching up to approximately 68,000 pounds depending on cargo and configuration.
Key factors such as truck size, material construction, axle configuration, and additional equipment influence the weight and performance of tri axle dump trucks. Understanding these elements enables operators and fleet managers to maximize efficiency, ensure regulatory compliance, and enhance operational safety.
As a leading supplier, KeyChain Venture Co., Ltd. provides tri axle dump trucks tailored to meet diverse customer needs, combining durability, performance, and optimized load capacity for commercial and industrial applications.

A typical tri axle dump truck can carry between 26 to 30 tons of material, equivalent to approximately 15 to 19 cubic yards depending on the material's density.
Empty tri axle dump trucks generally weigh between 25,000 and 35,000 pounds, varying by materials used in the truck body and equipment installed.
Yes, many tri axle dump trucks come with a liftable third rear axle to reduce tire wear and improve fuel efficiency when the truck is lightly loaded or empty.
Tri axle dump trucks haul materials such as sand, gravel, asphalt, riprap, construction debris, and other similar bulk goods.
Weight limits vary by state, but tri axle dump trucks may have a gross vehicle weight rating (GVWR) up to 70,000 pounds in many regions, with axle-specific limits that must be observed.
