Different Types of Hauling Equipment
Dump Trucks. Dump trucks are typically used to haul excavated material – like rocks and dirt – off the job site. A bed is mounted to a chassis or base frame. They have steering axles in the rear and front. Additional axles are added to handle heavier loads. A low wheelbase makes standard dump trucks easier to maneuver.

The need to optimize surface mining operations has led to the use of discrete event simulation (DES) modeling of truck-shovel systems. Often, these models assume truck cycle times are independent and identically distributed (iid) random variables, although, with significant bunching on the haul routes, this may not be valid.
