Kato KR25H-V5 (SR250VR)

The Kato KR25H-V5, also known as the SR250VR, is a 25-ton class rough terrain crane designed to deliver outstanding lifting performance, compact operability, and superior versatility for work in confined or rugged job site conditions. As part of Kato’s CREVO series, the crane combines cutting-edge hydraulic control with a refined ergonomic design, offering both functional power and operator-focused innovation.

At the core of the KR25H-V5 is a robust four-section telescopic boom constructed from high-tensile steel, which extends from 8.3 meters to 30.5 meters. The boom operates using a dual hydraulic cylinder with synchronized rope extension for smooth deployment and strong mid-range lifting power. In addition to the main boom, a 13-meter jib can be deployed at offset angles of 5°, 25°, or 45°, increasing the crane’s lifting height and radius to meet more complex site requirements.

The crane is powered by a Mitsubishi 6M60-TL diesel engine, which produces 199 kW (270 PS) at 2600 rpm and complies with the latest emission regulations. The engine is coupled to a fully automatic transmission system offering smooth gear changes across five forward and one reverse gear, ensuring excellent drivability on both highway and off-road surfaces. The 4×4 drive system, combined with front and rear oscillating axles and a minimum turning radius of just 5.6 meters, allows the KR25H-V5 to navigate tight, uneven terrain with ease.

Stability and safety are reinforced through a four-stage outrigger system with a maximum spread of 5.3 meters. Multiple extension positions enable flexible deployment in confined work areas, while advanced load moment limiting (AML) systems monitor lifting parameters in real-time to ensure safe operation. The outrigger’s design allows the crane to maintain high lifting capacity even on uneven surfaces.

The cab is designed with operator comfort and visibility in mind. It features an air-suspension seat, wide-visibility windows, multifunction displays, ergonomic controls, and automatic air conditioning. The full cab tilts up to 10°, providing optimal overhead visibility during high boom or jib lifts. Additional safety features include winch drum rotation indicators, over-wind prevention, moment limiters, and integrated camera systems for winch and rear view monitoring.

With a gross vehicle weight of approximately 20.3 tons, the KR25H-V5 is transport-friendly while retaining high structural strength. It is well-suited for a wide range of applications including urban infrastructure, steel structure assembly, utility work, and small-scale plant maintenance. Its CREVO-series design heritage ensures a blend of advanced lifting performance, user safety, and reduced environmental impact, making the KR25H-V5 a dependable and efficient solution in the 25-ton rough terrain crane class.
