The Kato HD513MRIII is a mid-size hydraulic crawler excavator manufactured by the Japanese equipment company Kato Works, featuring a compact design suitable for confined job sites. Powered by a turbocharged C 4D34-TLE2A diesel engine, this machine delivers 91.2 horsepower (68 kW) at 2,050 rpm, enabling efficient performance across diverse excavation tasks. The excavator operates at a total weight of 29,101 pounds (13,200 kg), with a ground pressure of approximately 6 psi, minimizing ground disturbance on sensitive surfaces. The hydraulic system incorporates dual piston travel motors and operates at 4,771.8 psi relief pressure, providing robust digging force and precise control. With three boom and stick configuration options, operators can achieve maximum digging depths ranging from 17 to 20 feet, maximum cutting heights from 28.3 to 30 feet, and maximum loading heights between 20.5 and 22.3 feet, depending on the selected configuration. The bucket system offers versatile capacity options from 0.4 to 0.8 cubic yards (ISO), accommodating various material handling requirements. Additional specifications include a 12.5 rpm swing speed, 3.2 mph maximum travel speed, and a compact tail swing radius of 5.6 feet, facilitating operation in restricted spaces. The machine features a comfortable operator cabin with low mechanical and hydraulic noise levels, enhanced visibility, and six-point viscous mounting for reduced fatigue. Fuel and hydraulic fluid capacities of 55.5 and 36 gallons respectively support extended operational periods. The HD513MRIII combines reliability with maneuverability, making it ideal for urban construction, utility work, and landscaping applications.
