Technical Description

The Kato HD550VIILC is a mid-size hydraulic crawler excavator designed for versatile earthmoving and construction applications. Powered by a Mitsubishi C 6D31T turbocharged diesel engine, the unit delivers 99.3 horsepower at 2000 rpm with maximum torque of 281 foot-pounds, providing robust digging force with a 302 cubic inch displacement. The excavator operates on a 24-volt electrical system and features a 90.9 gallon-per-minute hydraulic pump system with 4760 psi relief pressure, delivering responsive performance for precise excavation work. With an operating weight of 34,612.6 pounds and a 0.9 cubic yard reference bucket capacity, the HD550VIILC accommodates multiple boom/stick configurations to optimize reach and depth capabilities. Standard specifications include maximum digging depths ranging from 18.1 to 21.5 feet and maximum reach along ground from 27.1 to 30.3 feet, depending on configuration selection. The machine maintains a compact 8.5-foot track width and 8.2-foot tail swing radius, enhancing maneuverability in confined spaces. The undercarriage utilizes 48 shoes per side with seven track rollers and two carrier rollers per side, generating low ground pressure of 5.4 psi for minimal surface disturbance. Maximum travel speed reaches 3.5 miles per hour with impressive 33,700-pound drawbar pull capability. The swing mechanism rotates at 13.4 rpm for efficient repositioning. With a 66.1-gallon fuel capacity and 59.5-gallon hydraulic system fluid capacity, the HD550VIILC balances operational endurance with manageable maintenance requirements, making it suitable for quarrying, demolition, and general construction environments.
