Boom
100 ft. (30.t m) four section full power mechanically synchronized boom. Patented keel boom design utilizes a keep-shaped baseplate combined with a deep, four plate boom section to optimize strength / rigidity-to-weight ratio. Exclusive, patented color-coded boom and load charts allow the operator to easily and quickly determine boom extension, boom angle and load capacity. Maximum tip height with four section 100 ft. (30.5 m) boom is 110 ft. (33.5 m). Maximum tip height with optional two-stage 55 ft. (16.76 m) jib is 163 ft. (49.6 m).

Jib
22 ft. (6.7m) "A"-frame section attaches to sheave shaft of the 26 ft. (7.9m) triangular lattice "swingaway" boom extension. Jib stows beneath extension alongside base boom section or can be detached from "Swingaway" and held firmly in place on base section when extension is used independently. Jib can be offset from a minimum of 5 degrees to a maximum of 30 degrees and includes jib backstops, single rope self-equalizing suspension and removable pin type rope guard. Note - cannot be used with "telescopic swingaway" described below.

Cab
Full vision, all steel, fully enclosed, acoustically treated with tinted tempered safety glass throughout. (removable front windshield with storage provision and hinged skylight are tinted laminated safety glass). Sliding left side door and sliding right side window for ventilation. Adjustable full length control levers, combination hand and foot controls for swing and boom elevation. Fully adjustable operators seat with headrest. Complete engine instrumentation and controls. Combination hand and foot throttle. All-crane superstructure and outrigger controls, sight leveling bubble, electronic boom angle indicator, 20,000 BTU diesel fuel heater, electric windshield wiper,. defroster fan and swing horn; door and window locks, domelight, dashlight, 3-3/4 lbs. (1.7kg) dry type fire extinguisher.

Boom Extension
26 ft. - 46 ft. (7.9m - 14m) telescopic "Swingaway". 20 ft. (6.1m) rectangular roller mounted extension is manually extended and retracted from within 26 ft. (7.9m) lattice "Swingaway".

Boom Nose
Four sheaves, 13-3/4 in. (349mm) tread diameter, mounted on heavy duty tapered roller bearings. (Note - Three sheaves used when Grove Model 25H-16 main hoist specified). Removable pin type rope guards permit easy reeving. Rope dead ends provided on each side of main boom base. Note Cannot be used with 22 ft. "A"-frame described above.

*Boom Nose - Single 13-3/4 in. (349mm) tread diameter sheave auxiliary boom nose mounted to main boom nose with removable pin type rope guard for single part line work.

Boom Elevation
Single, 10 in. (254mm) bore, double-acting, hydraulic cylinder with integral holding valves. Combination controls provided for hand or foot operation.

Subframe
Cross-braced, closed-box style subframe yields greater strength and rigidity. Wheel base for standard truck crane mounting configuration is 261 in. (6.63 m).

Outrigger Controls
Independently controlled in-out-up-and-down from superstructure cab. Sequence control arrangement virtually elimintates accidental outrigger actuation.

Counterweight
Stationary mounted on turntable.
