摘要： A dump truck is provided with a frame, hinge pins and a body (5). The body is provided on a lower surface of a floor board (11a) thereof with a rail (12) along a longitudinal direction of the frame. The rail is a hollow structure member comprised of two side rail plates (12a) and a bottom rail plate (12b). The two side rail plates (12a) extend downwardly from the lower surface of the floor board (11a) of the body and oppose each other with an interval therebetween in a lateral direction of the frame, and the bottom rail plate (12b) is arranged in contact with respective lower end surfaces (12a-1) of these two side rail plates (12a). The dump truck (1) satisfies a relationship of Ts

摘要： Stresses are decreased at joints of a support structure disposed on a body of a dump truck. The dump truck includes a body frame (2), a body (2), a support structure (12) disposed on the body and supported by the body frame, and load transmission structures configured to transmit a load from the support structure to the body frame and, to transmit a reaction force from the body frame to the support structure. The support structure has a plurality of vertical plates (12a, 12b) and a bottom plate (12c). The vertical plates are arranged along a direction in which the reaction force is received from the body frame, and the bottom plate is maintained in upward contact with these vertical plates. The bottom plate is divided into first areas and a second area. The first areas include areas where the bottom plate is in contact with the vertical plates, and the second area is an area other than the first areas. The load transmission structures are configured to transmit the reaction force from the body frame such that a reaction force to be transmitted to each of the first areas becomes greater than a reaction force to be transmitted to the second area.

摘要： A dump truck pitching control system that can improve the ride quality of a vehicle body and the drive stability during traveling is provided. The present invention includes: a pitching state amount detection section 194 that detects a state amount of the pitching movement of the vehicle body 10; a spring characteristics calculation section 197 that calculates spring characteristics of suspension cylinders 30, based on detection results of stroke sensors 306, pressure sensors 307, and temperature sensors 308; a pitching target amount calculation section 192 that calculates a target amount of the pitching movement of the vehicle body 10, according to the spring characteristics calculated by the spring characteristics calculation section 197; and a torque correction value calculation section 193 that calculates a torque correction value required to correct the pitching amount, according to the spring characteristics calculated by the spring characteristics calculation section 197.
