Maneuverability - Two rotating turrets are provided, one at the pedestal (T-1) affording 270 degrees of rotation and one at the end of the first boom (T-2) with up to 224 degrees rotation.

Spacious Work Platforms are standard with all Aspen Aerial units. A variety of platforms are available including otation and extension features. All platforms are designed to be interchangeable.

Two Power Sources are provided. The primary source of power is a power-take-off from the truck transmission. A liquid-cooled diesel engine capable of powering the Bridge Inspection Unit is provided as a backup.

Accessories available include an air compressor with air supply at the work platform and truck deck, three-station communication system, 115V/220V electrical outlets, platform heaters, floodlights, tool trays and a platform cover.

Overhead Capabilities are available on every Aspen Aerial unit. There are no additional booms to attach and the third boom can be raised vertically.
