PURPOSE: To prevent the reversible connector of a tractor towing a large road construction machine from interfering with the operation of a machine by securing a slidable support means reversibly to a track means by use of a lock means, the track means being mounted on a conveyor.
CONSTITUTION: A reversible connector 32 mounted on the underside of a distal end 30 serving as the material inlet end of a conveyor 26 is engaged with the fifth wheel 70 of a tractor 72 by a king pin 50 projected from the king pin support plate 42 of a frame 36 supported slidably on an L-shaped track 34. The frame 36 is restrained from movement within the track 34 by a series of lock pins 52 and locked by a cotter pin. When the lock pin 52 is removed to slide the frame 36 backward to align a frame hole with a track hole 54 and the pin 52 is inserted, the frame 36 moves from a towing position to an operating position. Thus, a connection to the fifth wheel of the tractor can be made without interfering with the operation of a road construction machine.
