BOOM
Inverted T-cross section, 4-section telescoping type, extended and retracted proportionally by double-acting hydraulic cylinder and cable-crowd system. Easily replaceable and adjustable high-density nylon slide pads.

Quick Reeve Boom Point - Two high-density nylon load sheaves mounted on heavy-duty roller bearings. Two removable pin-type rope guards.

Boom Elevation - Double-acting hydraulic cylinder. Working range from 9° below horizontal to 80° above.

Load Hook - 5-ton (4,5 mton) capacity hook with heavy-duty swivel and weight is provided for single-line operation.

HOIST
Maximum theoretical line speed 247 fpm (75,3 mpm). Maximum theoretical bottom-layer line pull 12,000 Ib (5 443 kg). Two-speed planetary reducer. Spring-applied, pressure-released internal brake. Wet multi-disc internal brake is spring-applied, pressure-released.
Wire Rope – 335' (102,1 m) of 9/16" (14,3 mm) rotation resistant type.

SWING SYSTEM
Externally mounted, double-reduction planetary driven by hydraulic motor. Maximum theoretical swing speed 1.5 rpm. Spring-applied, pressure-released parking brake. Ball-bearing swing circle with external gear. 372° non-continuous rotation.

OUTRIGGERS
A-Frame link type with double-acting hydraulic cylinders operated independently for precise leveling. Bubble level located near outrigger controls.

MOUNTING
Pedestal and subframe are mounted to chassis by threaded rods and clamp plates. No welding, drilling, or bolting to truck frame is required.

Subframe - Torsion resistant, rigid 4-plate design. Mounted under crane full length of truck frame.

Rear Underride Protection - Supplied on factory mounted cranes. Fabricated structure mounted under rear of bed. Complies with Bureau of Motor Carrier Safety Standard 393.86.

Boom Rest - Heavy-duty fabrication. Easily removed to simplify loading and unloading truck deck.

CONTROL SYSTEM
Dual operator platforms are equipped with four single-lever crane controls arranged to ANSI B30.5 standards. Fully proportional control valves and system pressure gauge. Each station also includes outrigger and stabilizer controls, engine start/stop, foot throttle, signal horn, boom-angle indicator, bubble levels, load chart and range diagram.

HYDRAULICS
A 3-Section gear pump direct-mounted to power take-off on truck transmission provides 32 gpm (145 Ipm) to the hoist, 8 gpm (36 Ipm) to the swing circuit and 21 gpm (95 Ipm) to other crane functions.70-gallon (318 liter) baffled reservoir includes suction ball valve with strainer and 25-micron filter in the return line. Use of SAEO-ring and face seal O-ring hydraulic fittings throughout system. Aeroquip STC (Snap- to-Connect) on all hoses up to 1" virtually eliminates leaks.

Hydraulic Cylinders - All load-holding cylinders are equipped with integral holding valves.

WARNING SYSTEMS
Load Moment Indicator – CAN bus system maximizes expansion capabilities. Senses boom hoist cylinder pressure, boom length and boom angle. Audio-visual warning indicated overload conditions and overload shutoff feature prevents continuing overload. Operator can access all relative crane configuration and load conditions via display at the operator station. Internal boom length cable.

Radio Anti-Two-Block System - Audible warning and shutoff functions prevent hook from contacting boom point. Wireless system minimizes down time typically associated with damaged cables in wired systems.

Back-Up Alarm - Supplied on factory-mounted cranes, electronic audible motion alarm activated when truck transmission is in reverse gear.
