Kato NK-600RX

The Kato NK-600RX is a robust 60-ton class truck crane designed for heavy-duty lifting and efficient on-road travel. Its fully hydraulic system powers a round-shaped 5-section telescopic boom ranging from 11 to 43 meters, with extension and retraction driven by three hydraulic cylinders in combination with wire ropes. The boom extends smoothly from minimum to maximum in approximately 170 seconds and elevates between -2.5° and 81° in about 70 seconds. The crane also includes a two-section offsettable fly jib (with angles of 5°, 25°, and 45°) measuring 9.2 or 15 meters, increasing maximum lifting height to 58 meters.

The NK-600RX offers strong performance across a wide range of lifting scenarios, with a maximum rated capacity of 60 tons at 2.7 meters radius using 14 parts of line. Even with longer booms, it retains solid lifting capabilities: 14 tons at 35 meters boom length and 8 tons at the maximum 43 meters boom. The auxiliary hoist and main hoist deliver high line speeds (up to 114 m/min and 105 m/min, respectively), with automatic brakes, independent controls, and reliable drum locking systems. The slewing system uses an axial plunger motor with planetary gear reduction, providing a rotation speed of 2.1 rpm and a compact tail swing radius of 3,480 mm, ensuring stable operation in confined workspaces.

Mounted on the KT4060L or KT4060R carrier, the NK-600RX uses an 8×4 drive system powered by a Hino E13C-YY diesel engine producing 302 kW (approximately 405 hp) at 1,800 rpm, with maximum torque of 1,863 Nm at 1,100 rpm. The engine meets Euro III emissions standards and is paired with a 6-speed manual transmission plus 1 reverse gear. The chassis provides a maximum travel speed of 75 km/h and a gradeability of 35%.

The carrier itself measures roughly 13.37 meters in length and 2.8 meters in width, with a wheelbase of 6,700 mm, and it incorporates a hydraulic H-beam outrigger system providing a maximum extension width of 7 meters. The gross vehicle weight is approximately 41.2 tons, distributed over front and rear axles for optimal stability.

Safety and operational efficiency are supported by the Kato Automatic Crane System (ACS) with voice alarms, boom holding valves, over-hoist prevention devices, winch drum turning indicators, winch holding valves, automatic brakes, hydraulic safety valves, outrigger lock pins, and joystick control safety stops.

Standard equipment includes multiple hooks (60, 40, 20, and 4.5-ton), hydraulic oil cooler, rooster sheave, front jack, irregular winding prevention device, moment limiter, AM/FM radio, cab air conditioning, and other operator comfort features. Optional equipment such as cab heater, cooler, winch drum mirror, yellow reversing lights, and the Kato Crane Operation Recorder (K・COR) provide further customization for user needs.

Altogether, the NK-600RX combines powerful lifting performance, rapid cycle speeds, and the practical advantages of a high-speed truck-mounted crane, making it ideal for heavy construction, infrastructure projects, and utility work where both lifting capacity and travel mobility are required.
