Mine transport rail trolley linkage - with holes in carrier unit projections for load frame suspension cross pins

摘要

The under-flange track travelling trolley for mining operations can be coupled to other trolleys by traction or pressure rods, to form a trolley train. A carrier and traction unit (5) matches the width of the running rail flange (1a) and is connected on both sides with the bearing pins (3) for side plates (4) carrying the running rollers (2). In the projecting ends of the carrier unit there are vertical holes for cross pins (10) for suspension of the load frame (11). In each hole the head plate (9) carries a horizontal lengthways pin (13), with a prong piece (14) rotatably mounted on it, for accommodation of the traction rod (16), which is secured by a cotter pin.
