ABSTRACT:
An apparatus for displacing a line of track chain is disclosed which is employable for the purpose of disassembling, assembling, or reassembling the chain. A guide table for guiding movement of the chain is adapted to tilt only in the upward direction together with a pair of rails which are raised or lowered by actuating a first cylinder. A trolley moves forward and backward in the space as defined by both the rails by actuating a second cylinder while it is guided along the rails. The trolley is provided with an engagement rod which extends upwardly therefrom through a slot on the guide table to come in engagement to a bushing in the chain. Forward displacing of the chain is achieved by way of the steps of tilting up the guide table together with the rails by actuating the first cylinder, displacing the trolley forward by a distance equal to one pitch of the chain by actuating the first cylinder, lowering the rails to the lowermost position by retracting the first cylinder and displacing the trolley backward to the initial position by retracting the second cylinder. A distance of displacement of the chain is adjustably determined by selectively determining the position of two stoppers on a stationary screw spindle which is extended below the rails in parallel to the latter. Each of the stoppers is adapted to abut against an abutment member fixedly secured to the bottom of the trolley.
