A round shaft 12 is supported horizontally on both outer sides of the gantry body 1 by supporting both ends of the round shaft 12 by bearing pieces 13, and an arm 14 is mounted on the round shaft 12 so as to be slidable and rotatable. Is provided, and a triangular wheel stop 15 is provided at the tip of the arm 14.

Hinges 1 are provided on the upper edges of both front parts of the gantry body 1.
An inclined block 17 is connected via 6. The inclined block 17 has a gently inclined upper surface when extended forward, and can smoothly connect to the upper surface of the gantry body 1. A striped steel plate is used for the upper surface of the stopper 7 to prevent slippage, like the upper surface of the gantry body 1.

Reference numeral 18 denotes a lock mechanism provided to lock the tilt block 17 in a front extension state. The lock mechanism 18 includes a pawl member 19 fixed to an inner surface of the tilt block 17, and the gantry body 1. A movable claw 21 rotatably provided on the inner side surface of the movable claw 21 by a support shaft 20, a pedal 22 integrally formed with the movable claw 21, a coil spring 23 biasing the movable claw 21 forward, and A spring box 24 fixed to the inner surface of the gantry body 1 to hold the coil spring 23.
