Abstract: A mount and lift assembly for hydraulically driven snow blades or other accessories that includes a chassis frame for mounting to the vehicle chassis; a lift frame mount readily removably coupled to the chassis frame; an A-frame mount readily removably coupled to the chassis frame, the A-frame supporting an actuator drive such as an electric/hydraulic pump to drive the snow blade; a blade trip frame coupled to the A-frame; and a snow blade removably coupled to the trip frame.

Abstract: A power mast for the automatic vertical elevation and retraction of various devices, such as an antenna mounted on a communications vehicle. The mast is cable-driven, having a plurality of individual telescoping sections which allow for an overall collapsed height the same as or only slightly higher than the tallest such individual section. The cable is threaded around a series of pulleys, and is driven by a motor. Constant tension is maintained in the system, so that when in its operating or "up" position, the device is held in a stable condition until retracted.
