摘要： Disclosed is a body structure for a dump truck (1) having a body frame (3). The body structure is provided with hinge pins (5) to be located toward a rear of the body frame, a body (2A) to be tiltably disposed on the body frame via the hinge pins and to be adapted to load payload (9), and stiffening members arranged on outer surfaces of the body. The body is constructed at least of a floor board (62a), a front board (62b), side boards (62c), and a canopy (62d). The stiffening members include side-board stiffeners (61) connecting upper portions of elongated joints between the side boards and the front board to portions of elongated joints between the side boards and the floor board. The latter portions are located rearward of positions laterally corresponding to a barycentric position (G) of the payload (9) in a longitudinal direction of the body.

摘要： Provided is a dump truck capable of switching a destination of supply of hydraulic oil from a hoist cylinder to a fan motor at an appropriate time. A dump truck comprising: a hydraulic pump for discharging a hydraulic oil by a driving force of the engine; a hoist cylinder for raising and lowering a vessel by the hydraulic oil supplied from the hydraulic pump; a fan motor for driving a fan that supplies a radiator with cooling air by the hydraulic oil supplied from the hydraulic pump; a selector valve capable of being switched between a first position for supplying the hoist cylinder with the hydraulic oil discharged from the hydraulic pump and a second position for supplying the fan motor with the hydraulic oil; and a controller configured to, in a case where the selector valve is in the first position, determine whether an inflow pressure of the hydraulic oil flowing into the selector valve is less than a threshold value, and in a case of determining that the inflow pressure is less than the threshold value, switch the selector valve from the first position to the second position.

摘要： There is provided a dump truck that, when drive wheels (6) slip, is capable of reducing braking torques for the drive wheels (6) to avoid locking of the drive wheels (6), and of generating braking torques for driven wheels (7) to ensure an overall braking torque for the vehicle. The dump truck includes a controller (13) outputting a regenerative torque command value corresponding to an operation amount of a brake pedal (8) to an inverter (11), causing the inverter to regeneratively control electric motors (10), a hydraulic valve (15) for generating a hydraulic pressure corresponding to an operation amount of a brake pedal (9), rear wheel brakes (16) actuated by the hydraulic pressure from the hydraulic valve (15), a higher-pressure selecting valve (19) for selecting a higher one of the hydraulic pressure from the hydraulic valve (15) and a hydraulic pressure from a solenoid proportional valve (18), and front wheel brakes (17) actuated by the hydraulic pressure selected by the higher-pressure selecting valve (19). The controller (13) reduces the regenerative torque command value and output a drive command value corresponding to the reduction amount of the regenerative torque command value to the solenoid proportional valve (18), when the controller (13) determines that slip ratios of the rear wheels (6) are equal to or larger than a predetermined value.
