摘要： A mobile vehicle is disclosed having a boom pivotally mounted thereon for slewing about a vertical axis and a work head attached to the free end of the boom by a universal mounting. The universal mounting consists of a first housing having a base attached to the boom and a power driven worm in drive relation with a worm gear in the housing. The worm gear has a central hub to which is connected a second housing and which in turn has a driven worm in drive relation with a worm gear mounted therein. The worm gear in the second housing has a central hub and to which is attached a support carrying the work head.

摘要： A winch mounted directly on the gear of a worm gear drive unit and cantilevered outwardly therefrom through an opening in a housing in which the gear is journalled for rotation by a hub having a pair of spaced apart circular bearing lands journalled in apertures in a pair of spaced apart walls in the housing. The worm is journalled for rotation in the housing and meshes with the gear in drive relation. The worm is driven by a motor mounted on the housing.
