ABSTRACT:
A coupling device for mounting a material handling machine, such as a backhoe, on a civil engineering vehicle includes a first bracket assembly secured to the vehicle and a second bracket assembly secured to the machine. The first bracket assembly on the vehicle has a pair of coupling plate members, each of which has upper and lower pin-receiving concave seats that are open upwards. Either of the upper and lower pin-receiving concave seats are formed with locking slots, i.e., throat portions having a reduced width. A pair of upper and lower pins are adapted to be inserted into pin-attaching holes provided in the second bracket assembly secured to the material handling machine. The upper pins having width-reducing portions of a width slightly smaller than the width of the locking slots or throat portions continuous with either of the upper and lower pin-receiving concave seats. Because of the provision of the aforesaid upper and lower pin-receiving concave seats which are open upwards, the second bracket assembly may be simply mounted from above on the first bracket assembly, by placing the pins on the second bracket assembly in the pin-receiving concave seats provided in the first bracket, without an aligning operation of holes in one bracket with holes in another.
