Kato KR45H-VS (SS500S)

The Kato KR-45H-VS rough terrain crane is rated for a maximum lifting capacity of 45.0 tons at a 3.0-meter radius using a 10.4-meter boom. Its 4-section telescopic boom ranges from 10.4 meters to 39.0 meters and supports a 2-stage fly jib measuring from 5.5 to 13.7 meters. With the fly jib, the crane reaches a maximum lifting height of 54.5 meters.

Boom hoisting is handled by a powerful winch system with a hoisting/lowering speed of 128.0 m/min (main winch) and 110.6 m/min (auxiliary winch). The fly jib winch speed is 52.0 m/min, while boom elevation takes approximately 54 seconds from -0° to 82°. Slewing speed is rated at 2.4 rpm, allowing for smooth rotation.

The main winch uses an 18 mm × 220 m IWRC 6×Fi (29) wire rope, while the auxiliary winch uses 18 mm × 120 m rope. Hook options include a 45-ton main hook (5 sheaves) and a 20-ton hook (2 sheaves), providing flexibility for different lifting requirements.

The carrier is powered by a Mitsubishi 6D22TCT diesel engine producing 320 PS at 2,000 rpm with a maximum torque of 118 kgf·m at 1,400 rpm. It has a top speed of 49 km/h and gradeability of 0.6 tan (≈ 31°). The crane is mounted on a 4×4 drivetrain with hydro-pneumatic suspension and full steering on both axles.

The crane’s gross vehicle weight is approximately 37,610 kg, with an overall length of 11,620 mm, width of 2,850 mm, and height of 3,780 mm. Outrigger spread reaches up to 5.6 meters fully extended.

Additional features include ACS (Automatic Crane Safety) system, pilot-type hydraulic controls, and a centralized lubrication system for operational ease and safety. With a large 560-liter fuel tank and operator-friendly cabin, the KR-45H-VS is a reliable solution for heavy-duty rough terrain operations.
