A dump truck, which travels in travel directions and dumps loads in a dumping direction collinear to one of the travel directions, includes: a chassis provided with tires at front and rear parts in the travel direction; an obstacle detector provided at a dump-side end of the chassis, the obstacle detector detecting an obstacle in the dumping direction of the chassis; and a shifter that is capable of moving the obstacle detector to a first position at which the obstacle detector protrudes beyond dump-side ends of the tires and to a second position at which the obstacle detector is located inner than the dump-side ends of the tires.

A remotely controllable dump truck includes: a chassis; pairs of tires each provided at a front side and a rear side in a travel direction of the chassis; fenders for the tires; and a vehicle-status-output device disposed between a front one of the fenders and a rear one of the fenders, the vehicle-status-output device including a control panel for outputting status information of the vehicle. The vehicle-status-output device is positioned, in a width direction of the chassis orthogonal to the travel direction, to be offset from ends of the front and rear one of the fenders in the width direction, and the control panel faces an outside of the tires in the width direction.

An antenna attachment structure attaches a plurality of antennas to a dump truck including a chassis and a dump body rotatably provided on the chassis, the dump body covering the chassis across an entire length and entire width thereof in a plan view. The antenna attachment structure includes: an antenna attachment portion to which the plurality of antennas are attached and rotatably attached to each of lateral surfaces of the dump body; and a parallel link mechanism including the antenna attachment portion and a rotation center of the dump body and configured to keep a constant posture of the antenna attachment portion when the dump body is rotated.

A backhoe loader includes cab, a loader, an engine, and a backhoe. The loader includes a pair of loader arms sandwiching the engine from the side, a loader bucket, and a loader bucket cylinder. There is provided a foot mount member attached at the outer side of the loader arm to be horizontal relative to the ground in a state where the bottom of the loader bucket is in contact with the ground. Thus, a backhoe loader of favorable workability in the maintenance service of engine can be obtained.
