Formed pentagonal 6-section telescoping type, extended and retracted sequentially and proportionally by a double-acting hydraulic cylinders and cable-crowd system. Easily replaceable and adjustable high-density nylon slide pads.2085TM 6-Section 85’ (25.9m) Combination Sequential & Proportional BoomQuick 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.
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 – 300’ (91,4 m) of 9/16" (14.3 mm) rotation resistant type.
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.
Out and Down Outriggers type with double-acting hydraulic cylinders operated independently for precise leveling. Bubble level located near outrigger controls.
7’-5” (2.25 m) H-Style Rear Stabilizers or Optional A-Frame Style
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 which is mounted under crane.Boom Rest - Removable Heavy-duty fabrication mounted behind the cab.
Dual operator platforms are equipped with four single-lever crane controls arranged to ASME 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.
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.Hydraulic Cylinders – All load-holding cylinders are equipped with integral holding valves.
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.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. Internal wired Anti-Two-Block System option available.Back-Up Alarm – Supplied on factory-mounted cranes, electronic audible motion alarm activated when truck transmission is in reverse gear.
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 AMSI 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.
