Abstract
A dump truck (10) has a tipping body (30) in the form of a shell structure for holding material, which is pivotally mounted to the chassis (19) of the dump truck (10) for tilting about a transverse tipping axis. The truck (10) has at least one hoist pivot (33) configured for connection to a respective tipping ram (18) mounted to the chassis (19). The hoist pivot (33) is positioned to abut against the underside of the shell structure (36) when acted upon by the tipping ram (18) and tilt the tipping body (30) about the tipping axis. However, the hoist pivot (33) is not integral or welded to the shell structure (36). High stress concentrations are thereby avoided or significantly lessened in the tipping body shell in the vicinity of the hoist pivot, and there are no welds between the hoist pivot and the shell structure to become fatigued or crack. This enables a simplified and lighter single skin shell structure to be used for the tipping body.
