New Generation Mobile Crane Rigo RT 500
Italian manufacturer AUTOGRU RIGO S.r.l. has updated its 50 tonne capacity mobile crane Rigo RT 500. The machine is equipped with a telescopic boom with four cold bent special steel sections, from 10.5 to 35 meter length, fully hydraulic with proportional extension. Boom angle is from -1° to +80°.
The crane is equipped with a 2 speed main winch with epicyclical reduction gear, hydraulic motor, automatic brake and block valve.
The speed of the main winch is from 0 to 110 m/min, max permissible line pull – 55 kN, diameter / rope length – 16 mm/180 m.
The speed of the auxiliary winch is from 0 to 110 m/min, max permissible line pull – 55 kN, diameter / rope length – 16 mm/180 m.
Rigo RT 500 is powered by IVECO Nef (Comon-Rail) turbo after-cooled a 6 cylinder in line, water cooled, developing 230 HP (169 kW) at 2.300 rpm. Fuel tank is 200 liter. The engine is combined with a hydrostatic transmission with pump and variable displacement hydraulic motor; there are 2 forward and 2 reverse speeds.
Overall dimensions in transport position: length - 12620 mm, width - 2550 mm, height - 3350 mm. The overall weight is 32 tons.
The crane has designed and produced by RIGO box section cold bent carrier made in high resistance steel with integral outriggers. There are 4 hydraulic telescopic outriggers with block valves, operating from the cabin.
Excellent maneuverability is provided by four steering modes: front only, rear only, crab and coordinated. Enhanced tyres 16.00 R25 are suitable for work in construction sites and off-road conditions. Maximum travel speed is 40 km/h.
The brake system includes standard hydraulic brakes with double circuit and a parking brake on transmission.
Rigo RT 500 is equipped with panoramic and ergonomic cabin, with safety glasses; adjustable seat, conditioner, and complete instruments. There is an electrical proportional control with a joystick and automatic return to “0” position.
Slewing system provides 360° rotation by planetary swing; hydraulic motor and multi-discs automatic brake. The distance between pinion and slew-ring can be adjusted.
Safety equipments are certified according to European norms and include block valve on all cylinders, overpressure and counterbalance valves, and electronic safe-load moment indicator.
Auxiliary winch with rope and 6 tons hook block.
