BOOM Inverted T-cross section, 3-section telescoping type, extended and retracted proportionally by a double-acting hydraulic cylinder and cable-crowd system. Easily replaceable and adjustable high-density nylon slide pads.
3051T – 3-Section 51 ft (15,5m). Tractor Mount.
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 9Þ below horizontal to 80.6Þ above.
Load Hook – 7-ton (6,4 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 lb (2 227 kg). Two-speed planetary reducer. Wet multi-disc internal brake is spring-applied, pressure-released.
Wire Rope – 380' (115,8 m) of 5/8" (16 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. 372Þ 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 – Torsional resistant, rigid 4-plate design. Mounted under crane the full length of truck frame.
Rear Underride Protection – Supplied on factory-mounted cranes. Fabricated structure mounted under rear of bed which complies with Bureau Motor Carrier Safety Standard 393.86.
Boom Rest – Heavy-duty fabrication mounted behind the cab.
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 container, load chart, and range diagram.
HYDRAULICS Hydraulic System – A 3-section gear pump direct-mounted to power take-off on truck transmission provides 32 gpm (133 lpm) to the hoist, 8 gpm (30 lpm) to the swing circuit and 21 gpm to the other crane functions. 70-gallon baffled reservoir includes suction ball valve with strainer two 25-micron filters in the return line. Use of SAE O-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.
Externally Wired 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 with hermetically sealed power in relays. Enclosure includes power in relays and circuit status LEDs which are designed to withstand high pressure 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.
