Kato KR20HL (SR200R)

The Kato SR-200R (model KR-20H-L) is a 20-ton class rough terrain crane launched for the Japanese domestic market in April 2005. It was introduced as a high-performance, environmentally conscious lifting solution with a compact design. The crane delivers a maximum lifting capacity of 20 tonnes at a 3.0 m working radius, and it achieves this without exceeding a 20-ton operating weight, making it suitable for road travel and quick deployment on tight sites.

Its main boom extends from 8.65 m to 28.0 m through a four-section synchronized telescoping system known as Synchro-Zoom, allowing proportional and smooth extension across all sections. This contributes to efficient, stable lifting and reduced operation time. A two-stage jib extends from 7.0 m to 11.4 m, enabling a maximum lifting height of 40 m when fully deployed with the jib. Tip performance at 28.0 m is rated at 2.5 t (with 1 fall), and jib performance peaks at 0.43 t at 34.0 m radius.

Powering the SR-200R is a Mitsubishi 6D16-TLE2B engine, delivering 170 kW (231 PS) at 2700 rpm and peak torque of 705 Nm at 1300 rpm. The machine features a 2-way or 4-way drive switchable system with hydraulic steering, 49 km/h top travel speed, and 60% gradeability. Despite its compactness, it boasts a stable base of 5.4 m when the outriggers are fully extended.

The cab is designed for comfort and functionality, with amenities including air conditioning, digital meters, and ergonomic seat adjustments. For safety, the SR-200R is equipped with the ACS automatic moment limiter, a range limiter, boom/jib angle monitoring, and emergency shut-off switches. Optional accessories include working cameras, TV systems, and external ACS alarms.

This crane has been optimized for ease of transport, operation, and service, ensuring it remains one of the most balanced rough terrain cranes in its class for general construction and confined job sites.
