摘要
The railway track sleeper, rail and yoke laying equipment incorporates two gantries and a raisable and lowerable laying beam. The gantries (3) are hinged to the ends of a connecting girder (4), to swivel about vertical pivot pins (5). Their supports are circular columns (9), surrounded by horizontally swivelling bogie frames (10). Support legs (12) can swing upwards about horizontal bolts (11), and there are motors and driving wheels (15) to shorten and/or narrow the structural dimension.
