Abstract
A heavy-duty lifting and tilting device having features which make it especially advantageous for incorporation in garbage trucks and the like. The highly-stressed components of the device are short and compact, being particularly arranged to produce a sturdy mechanism that is well adapted to withstand rough handling and abuse when in use. Additionally, the device provides the greatest possible ground clearance, which is of great importance when the truck is traversing uneven terrain, in a heavily-loaded condition.
