multi ruettelverdichtungsmaschine for the construction of motorways

摘要

A vibro-compacting machine has two components pivotally interconnected for relative swinging movement about a vertical axis. One unit is a vibrating metallic drum and the other unit has pneumatically tired wheels. The distance between the two axes is not more than four meters and the pneumatic tires press on the ground with a force of about 9.2 metric tons while the vibrating drum presses on the ground with a force of about 5.8 metric tons. The width of the drum is about 1.5 meters, which is greater than the track of the wheels. The wheels are isostatically suspended so that they all press on the ground with equal force.
