COUPLING DEVICE OF TRUCK

PROBLEM TO BE SOLVED: To provide a coupling device of a truck capable of improving safety of the device and shortening working hours in separating work and connecting work of the truck. SOLUTION: This coupling device of the truck is furnished with a connecting shaft 12 free to rotate around the axis and projecting toward another truck 6 which is a connecting object and forms a projected part 13 projected from a peripheral surface of this connecting shaft 12. An operating part 16 to rotate the connecting shaft 12 around the axis is set on a side part in the truck widthwise direction of the other truck 6. The connecting work and the separating work of the truck are carried out by switching the operating part 16 provided on the side part of the truck 6 to a first rotating position free to insert the projected part 13 into a slot 14 formed on the other truck 6 and a second rotating position free to engage the projected part 13 with the slot 14 by operating it. Consequently, it is not necessary for a worker to go to the center in the truck widthwise direction as before but possible to shorten the workhours. Further, there is no danger for the worker to be caught in between the trucks 6. COPYRIGHT: (C)2008,JPO&INPIT
