Haul trucks are heavy-duty vehicles used in construction and mining to transport large volumes of materials. They have a driver’s cab and a large haul bed, with a design that accommodates heavy loads and off-road use. Special licensing and safety precautions are required to operate them on job sites.
A haul truck is a heavy truck used in construction and mining to transport materials such as crushed rock. Haul trucks are similar in design to dump trucks, but tend to be stronger and also much larger, as they are intended for applications where large volumes of material need to be moved on a regular basis. Various manufacturers produce a range of trucks of different sizes and can customize them to order for particular applications, such as working in extremely hot or cold environments where normal models can be subject to breakdown.
The transport truck includes a driver’s cab and a large haul bed. The bed can be tilted to unload loads and can also have doors that open to release the contents. Haul trucks have a very high weight rating and a design that will accommodate extremely heavy loads. Rocks, broken concrete, and other materials found around mining and large construction sites tend to be heavy and high volume, making a specialized haul truck necessary.
The design features two axles, with reinforcement and large tires to keep the truck as stable as possible on the job. Most haul trucks are intended for off-road use in environments where the terrain can be uneven. They have strong shocks and other features for stability, though comfort is generally not high on the designer’s list of priorities. Top speeds tend to be limited, as haulage trucks travel in conditions where they need to move slowly, and increasing the speed would require substantial changes to the engine design.
To drive a transport truck, a special license is usually required. The license qualifies the driver to drive heavy vehicles. Employers may sponsor the licensing process and may provide training in controlled areas. Drivers can also attend a heavy truck school to gain experience and learn about the laws related to heavy truck driving. Training generally includes safety precautions, as the moving parts of a transport truck can pose a risk to drivers and bystanders. For example, drivers must learn how to safely release a load.
On a job site, semi-trucks and other heavy vehicles have the right-of-way because they are more difficult to turn and stop. Light trucks and smaller construction equipment must give way for safety. On hills, any truck going up has the right of way. Helmet requirements are typically in effect around construction sites and equipment like haul trucks. Visitors to a site must pick up hats at the building office before they can walk.
