Haul trucks are large vehicles designed for transporting heavy materials, primarily in mining and construction industries. They have a robust structure and powerful engines to carry significant loads over rough terrain. These trucks can typically carry between 40 to 400 tons of material, making them essential for moving earth, rocks, and other heavy items. The design of haul trucks includes a wide, open bed for easy loading and unloading. They often feature large tires to navigate uneven surfaces and are equipped with advanced technology for safety and efficiency. Common brands of haul trucks include Caterpillar and Komatsu.
