STANDARD UPPERSTRUCTURE EQUIPMENT
UPPERSTRUCTURE FRAME All welded one-piece structure fabricated with high tensile strength alloy steel. Counterweight is bolted to frame. TURNTABLE CONNECTION Swing bearing is a single row, ball type, with external tooth. The swing bearing is bolted to the revolving upperstructure and to the carrier frame. SWINGA hydraulic motor drives a double planetary reduction gear for precise and smooth swing function. Swing speed (no load) is 2.8 rpm. SWING BRAKE Heavy duty multiple disc swing brake is mechanically actuated from operator’s cab by foot pedal. Brake may be locked on or used as a momentary brake. RATED CAPACITY INDICATOR Rated Capacity Indicator with visual and audible warning system and automaticfunction disconnect. Second generation pictographic display includes: boom radius, boom angle, boom length, allowable load, actual load, and percentage of allowable load registered by bar graph. Operator settable alarms provided for swing angle, boom length, boom angle, tip height and work area exclusion zone. Anti-two block system includes audio/visual warning and automatic function disconnects.OPERATOR’S CAB Environmental cab with all steel construction, optimum visibility, tinted safety glass throughout, and rubber floor matting is mounted on vibration absorbing pads. The cab has a sliding door on the left side; framed sliding window on the right side, hinged tinted all glass skylight and removable front windshield to provide optimum visibility of the load open or closed.
