Specifications include, but are not limited to: A.Ground to Bottom of Platform Height: 55.1 ft at 10.0 ft from centerline of rotation (16.8 m at 3 m) B.Working Height: 60.1 ft (18.3 m) C.Maximum reach to edge of platform: 37.7 ft at 31.0 ft platform height (11.5 m at 9.4 m) D.Rotation: Continuous E.Upper Boom Articulation: 0 to 173 degrees. Insulator provides a minimum of 162 in (411 cm) of isolation. F.Lower Boom Articulation: 0 to 105 degrees. Insulator provides a minimum of 24 in (610 mm) of isolation. G.Lower Boom Stow Protection: To help prevent excessive down pressure by boom structures when stowing. H.Upper Controls: The Altec ISO-Grip (U.S. Patent No. 7,416,053) System includes the following boom tip components that can provide an additional layer of secondary electrical contact protection. This is not a primary protection system. 1. Control Handle: A single handle controller incorporating high electrical resistance components that is dielectrically tested to 40 kV AC with no more than 400 microampers of leakage. The control handle is green in color to differentiate it from other non-tested controllers.The handle also includes an interlock guard that reduces the potential for inadvertent boom operation. 2. Auxiliary Control Covers: Non-tested blue silicon covers for auxiliary controls. 3. Control Console: Non-tested non-metallic control console plate. 4. Boom Tip Covers: Non-tested non-metallic boom tip covers. The covers are not dielectrically tested, but they may provide some protection against electrical hazards. I.Lower Controls: A lower control station is located on the curb side of the turntable with the control valves under a protective cover. A selector valve at the lower control station is provided to override the upper controls.J.Platform Leveling System: The platform is leveled by a single leveling chains with fiberglass rods in lower and upper boom, designed to maintain the dielectric integrity of the aerial device. Controls for tilting the platform are located at the platform. The mechanism for tilting the platform includes one dual acting cylinder incorporating counterbalance load holding valves to lock the platform in the event of hydraulic line failure.
