Product Description

The Kobelco RK450-2, or Panther 500, is a reliable and rugged rough terrain crane developed for mid-range lifting applications in both urban and off-road environments. This 45-ton crane is powered by a Mitsubishi 6D22TC diesel engine that delivers 265 kW (360 PS) at 2,000 rpm, paired with a 5-speed automatic transmission with Hi/Low range selection. The machine’s 4×4 drive system and long wheelbase ensure excellent traction and stability across all jobsite conditions.

Its telescopic boom extends from 10.2 meters to 40.1 meters across five hydraulic sections, with a max rated lifting capacity of 45,000 kg at 3.0 meters. For extended reach, a two-stage lattice-type fly jib is available, offering a length of up to 13.7 meters with offset angles from 5° to 45°, enabling total lifting heights over 54.8 meters. The boom angle ranges from -2° to 80.5° and is operated via synchronized hydraulic cylinders, achieving hoist-up speeds of 105 m/min (2nd layer) and boom elevation in 40 seconds.

The crane is equipped with main and auxiliary winches utilizing 18 mm IWRC wire ropes (220 m and 120 m, respectively), powered by axial piston hydraulic motors with planetary reduction gears and holding brakes for safe and smooth hoisting operations.

Its hydraulically controlled outrigger system offers multiple extension configurations (7.2m/6.8m/5.4m/3.8m), and a range of automatic safety systems including an AML (Automatic Moment Limiter), load moment indicator, angle indicators, boom length sensor, and outrigger monitoring, ensure safe lifting in all configurations. The cab is operator-friendly, with panoramic visibility, climate control, and a multi-display system that integrates various operational diagnostics.

With a max travel speed of 49 km/h and a compact turning radius of just 10.6 meters, the RK450-2 is highly mobile. The total machine length is 12.2 meters with an overall weight of 37,570 kg, carrying up to 300 liters of fuel for long operation intervals.

The RK450-2 is a top-tier option for lifting contractors seeking performance, flexibility, and reliability in the 45-ton class.
