Abstract
A 240 degrees radially rotatable deck assembly rotatable in either direction without requiring resetting in a park position and requiring only a rotatable outer ring of a slew gear connected to a rotatable sub-frame attached to the deck, a fixed inner ring of the slew gear affixed to a fixed sub-frame fixed to a frame of the assembly and only a single hydraulic motor requiring no cylinders and only one main valve body with incorporated electric solenoids reducing the complexity of the plumbing and the weight of the assembly resulting in lower construction and maintenance costs, improved fuel economy and allowing an increased load weight. The assembly includes a positive holding brake that eliminates blow-by of the rotating section and is rotatable in either direction without requiring being reset in a park position. Such a deck is especially useful on a tow truck.
