Dump trucks are used in a variety of industries and for many purposes. Dump trucks carry loose material such as soil, rock, or road salt. Some dump trucks are capable of carrying payloads up to 26 tons. With a capacity for high payloads, rollovers are a major consideration for dump trucks. Drivers should always obey local speed limits and traffic laws to minimize a rollover or accident. In addition, drivers should always follow safe driving procedures and observe all safety guidelines.

Dump truck are most susceptible to rollover when a fully loaded box is raised. Box stability can be adversely affected by a number of issues including:

  • Uneven surface or truck footing.
  • Inconsistent flow of the materials from the box, leaving a large amount of material in the upper portion of the raised box.
  • Load shift occurs during dumping causing the rear wheels to shift unevenly.

Dump truck rollover risk can be minimized by through good dumping practices.

Dumping Best Practices:

  • Before dumping a load, perform a visual inspection all the way around the dump truck. Ensure there is plenty of space next to the truck; do not park directly next other vehicles.
  • Verify the truck is parked on a level surface and that all wheels have solid footing.
  • Check to make sure the tailgate is unlocked and inspect for sufficient clearance before lifting the box.
  • Notify workers in the area to stand clear prior to dumping the box.
  • If you start to experience poor flow, lighten the load in the top end of the box. Smaller loads tend to flow better than a full load and also reduces the rollover risk.
  • Consider using a box liner which can improve material flow as well as maintain the condition of the box over a longer period of time.
