Kato SL-600RfIII Load Chart PDF + Specifications

The Kato SL-600RfIII, designated KR-60H-F2, was developed to serve contractors requiring greater lifting capacity while retaining the flexibility and maneuverability of a rough terrain crane. It follows the successful concept introduced on the SL-500RfIII but increases the rated lifting capacity to 60 tonnes while extending the hydraulic SL Jib to a maximum length of 16.5 m. The crane is particularly suited for steel erection, bridge construction, industrial plant maintenance, and urban projects where crane repositioning is restricted.

At the heart of the crane is a five-section box-type hydraulic telescopic boom extending from 10.1 m to 40.0 m. The boom utilizes synchronized telescoping with the third, fourth, and fifth sections extending simultaneously. Maximum rated lifting capacity is 60,000 kg at a 1.8 m radius on the fully retracted boom using 13-part reeving. Capacity ratings include 30 tonnes on the 17.6 m boom, 15 tonnes on the 25.1 m boom, 12.5 tonnes on the 32.5 m boom, 9 tonnes on the 36.5 m boom, and 7.5 tonnes on the fully extended 40.0 m boom. Maximum boom tip height reaches 41.1 m.

One of the defining characteristics of the SL-600RfIII is its SL Jib system. Unlike conventional lattice fly jibs, the SL Jib is a hydraulically telescoping box-section jib that can be extended from 8.92 m to 16.5 m and hydraulically luffed through offsets ranging from 5° to 60°. This enables operators to adjust jib angle and length from the cab without manual reconfiguration. Maximum rated capacities are 4.2 tonnes on the 8.92 m jib, 2.8 tonnes on the 12.7 m jib, and 2.0 tonnes on the fully extended 16.5 m jib. With the boom fully extended and the SL Jib installed, the crane achieves a maximum lifting height of 57.5 m.

The hoisting system consists of dual independent hydraulic winches driven through planetary gear reduction units with integrated negative brakes. Main hoist rope speed reaches 135 m/min, while auxiliary hoist speed reaches 128 m/min. High-speed lowering is available at approximately 157 m/min under no-load conditions. Main hook lifting speed is 10.3 m/min using 13-part reeving, while the auxiliary hook can achieve 128 m/min on a single line.

Boom elevation ranges from 0° to 84°. Full boom raising from horizontal to maximum elevation takes approximately 49 seconds, while extension of the full 29.9 m telescoping stroke requires approximately 97 seconds. Slewing is powered through a hydraulic motor and planetary gearbox arrangement with selectable high and low speeds, providing a maximum slewing speed of 1.75 rpm. Rear swing radius is maintained at only 3.55 m, allowing efficient operation in confined jobsites.

The crane is supported by a fully hydraulic H-type outrigger system with integrated float and vertical cylinders. Six outrigger widths are available: 7.6 m, 7.2 m, 6.5 m, 5.4 m, 4.3 m, and 2.43 m. Individual load charts are provided for each outrigger configuration, allowing safe operation in restricted working environments where full extension is not possible.

Power comes from a Cummins QSL9-4C diesel engine compliant with Japan’s 2014 diesel emissions regulations. The six-cylinder, water-cooled direct-injection engine displaces 8.849 litres and produces 254 kW (340 hp) at 2,100 rpm with a peak torque output of 1,526 Nm at 1,400 rpm. The engine is coupled to a fully automatic transmission with manual shifting capability, six forward gears, and two reverse gears. A torque converter with automatic lock-up clutch improves fuel economy and drivability.

The carrier utilizes a three-axle chassis designated YDS-KRC027. Drive configuration is selectable between 6×2 and 6×4. Maximum travel speed is 49 km/h while gradeability reaches 60 percent. Five steering modes are available, including front-wheel steering, counter steering, crab steering, rear-wheel steering, and independent steering. The minimum turning radius is only 6.7 m when using six-wheel steering.

Safety is managed through Kato’s ACS (Automatic Crane System) overload prevention system with voice warning capability. Additional systems include automatic swing stop, anti-two-block protection, work area limitation, automatic outrigger width detection, electronic level indicator, boom and jib lowering prevention systems, winch protection devices, swing lock, and outrigger lock mechanisms. Higher specification packages can also be equipped with Kato’s Safety View System, featuring surround-view cameras, human detection assistance, a 12.1-inch touch-screen monitor, PDF display capability, and clearance sonar systems.

The operator cab includes automatic climate control with dehumidification function, liquid-sealed cab mounts, a fully adjustable suspension seat with armrests and headrest, power windows, intermittent front and roof wipers, USB power outlets, Bluetooth audio capability, winch monitoring camera, LED work lights, and other features designed to improve comfort during long working shifts.

Overall dimensions are 12.475 m in length, 2.75 m in width, and 3.73 m in height. Gross vehicle weight is approximately 35.9 tonnes. Despite its larger lifting capacity, the crane remains highly maneuverable and roadable, making it suitable for a wide variety of construction and industrial lifting applications.
