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 9.5° below horizontal to 80.5° 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 11,500 Ib (5 216 kg). Two-speed planetary reducer. Wet multi-disc internal brake is spring applied, pressure-released.

Wire Rope - 300' (91,4 m) of 9/16" (14.3 mm) 6x19 EIPSIWRC.

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.

STABILIZERS
A-frame, 10' extension, operated independently for precise leveling.

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 - Torsionally 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 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, beverage holder, load chart, and range diagram.

HYDRAULICS
A 3-section gear pump direct-mounted to power take-off on truck transmission provides 32 gpm (133 Ipm) to the hoist, 8 gpm (30 Ipm) to the swing circuit and 21 gpm to the other crane functions. 70-gallon baffles reservoir includes suction ball valve with strainer and two 25-micron filters in the return line. Use of SAE o-ring and face seal o-ring hydraulic fittings throughout system.

WARNING SYSTEMS
Load Moment Indicator - CAN bus system (2281 Ci maximizes expansion capabilities. All models sense boom hoist cylinder pressure, boom length and boom angle.
Audio-visual warning indicated overload conditions and overload shutoff feature prevents continuing overload. Digital 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.

GENERAL
Electrical - State-of-the-art, weather-resistant components throughout. Hermetically sealed enclosure includes power in relays and circuit status LEDs. Designed to withstand high pressi/e washing and varying climates.

Design/Welding - Design conforms to ANSI B30 5 Welding conforms to AWS D1.1. Tested to SAE 1063 and SAE 765.

Manuals - Operator, service and parts manuals depict correct crane operation, maintenance procedures and parts listing.

Warranty -12-month warranty covers parts and labor resulting from defects in material and workmanship.

Note: In order to ensure continuous improvement, specifications may change without notice.
