What is a dump truck?
A dump truck is a type of heavy truck with a special design that is used to carry heavy loads in the mining and construction industries. Due to their structural features, these mining machines are capable of moving a large volume of minerals, soil, rocks, and building materials.
Dump trucks are produced in different types with different capacities, and due to their robust design and powerful engines, they are able to operate in harsh mining conditions. Dump trucks are used in different environments and for specific purposes. In mines, for construction, road construction, waste factories, concrete production plants, dam construction projects, metal industries, and …, dump trucks are used.

Types of dump trucks
1. Articulated Dump Trucks:
Articulated dump trucks are highly flexible due to their multi-section design and can easily move on uneven terrain and complex routes. This type of dump truck is mostly used in projects with limited routes or difficult environmental conditions such as mud or narrow roads.
Due to their small turning circle, articulated dump trucks are excellent for large projects with limited space. The capacity of these dump trucks is usually between 20 and 40 tons. The robust body and ergonomic design of this dump truck improve the efficiency and safety of operations.
2. Rigid Dump Trucks:
Rigid dump trucks are among the most widely used types of dump trucks in open pit mines due to their stable design and sturdy chassis. These dump trucks are specifically designed to transport heavy minerals over long, open routes.
The carrying capacity of this type of dump truck ranges from 30 to 400 tons. It is variable and their powerful engines allow the movement of heavy loads on steep slopes. The use of rigid dump trucks in open pit mines increases the speed of material transportation and reduces operation time.

3. Track Dump Trucks:
Track dump trucks are specifically designed for off-road applications, and are one of the best options for soft, muddy, and sandy terrain. The track wheels of this type of dump truck provide greater stability and stability on difficult terrain and allow for easy movement in harsh environmental conditions.
These dump trucks (also called crawler trucks) usually have a lower carrying capacity than rigid types, but are used in construction projects and some mines due to their high maneuverability in certain environments. The robust and simple design of these dump trucks reduces maintenance and repair costs.

Rail Dump Trucks :
Rail dump trucks are a special type of dump truck that runs on rail tracks and is used to transport minerals along predetermined routes. These machines are mostly used in projects that require frequent and high-volume transportation.
Rail dump trucks are popular in some large and old mines due to their reduced fuel consumption and high efficiency in transporting heavy loads. This type of machine can travel on both regular roads and rail tracks. Often, a rail dump truck has all the features of a regular dump truck, which can travel on rail tracks by lowering its rail wheels.

Underground Dump Trucks:
Underground dump trucks are specially designed for moving minerals in underground mines. These types of dump trucks are smaller in size to easily move through tunnels and confined underground passages. Their design includes low height, strong chassis and ventilation systems suitable for underground environments. Underground dump trucks can be used in hard underground mines, soft rock and tunnel construction.
Electric Dump Trucks:
Electric dump trucks are one of the newest types of dump trucks that greatly reduce fuel costs due to the use of electric motors. These dump trucks are particularly popular in underground mines and environments where reducing environmental pollutants is important. The electric motors of these dump trucks not only reduce pollution, but also provide high efficiency. Using electric dump trucks in modern mining projects can help reduce operating costs and increase environmental compatibility.
