Hitachi KH850-3 Crawler Crane The Hitachi KH850-3 is a 150-ton crawler crane with an 18-meter basic boom, extendable to 84 meters, and an optional jib ranging from 13 to 31 meters. Powered by an Isuzu 6RB1T engine producing 206 kW (280 PS), it is designed for heavy-duty lifting, with a maximum boom and jib length reaching 103 meters.
Product Description The Hitachi KH850-3 is a high-capacity crawler crane engineered for heavy lifting tasks with a maximum rated load of 150,000 kg (330,700 lbs) at a 5.0-meter working radius. The crane is equipped with a basic boom length of 18 meters (59’1″), which can be extended to a maximum length of 84 meters (275’7″) to accommodate a wide range of construction needs. It also features a jib extension option, with lengths from 13 meters (42’8″) to 31 meters (101’8″), allowing for a maximum combined boom and jib length of 103 meters (337’11”).
The KH850-3 operates efficiently with its dual-mode swing speed control, providing high-speed rotation of 0 to 2.0 rpm and low-speed rotation of 0 to 1.2 rpm. The travel speed of the crane is similarly adjustable, with a high-speed setting of up to 1.2 km/h (0.75 mph) and a low-speed option of 0.8 km/h (0.50 mph), ensuring smooth maneuverability on job sites.
The crane boasts excellent gradeability, capable of handling slopes up to 17° (30%), and its ground pressure is approximately 0.91 kgf/cm² (12.9 psi), ensuring stable operation even under heavy loads. The crane’s operating weight is substantial, at 150,000 kg (330,700 lbs), which includes the 150-ton capacity hook and 57,700 kg (127,200 lbs) counterweight.
Powering the KH850-3 is an Isuzu 6RB1T turbocharged diesel engine, which delivers a rated horsepower of 206 kW (280 PS) at 2,000 rpm. This robust engine provides the necessary power for lifting operations and ensures reliable performance in demanding environments.
With its impressive lifting capabilities, long boom and jib reach, and efficient powertrain, the Hitachi KH850-3 is well-suited for a variety of large-scale construction projects, including infrastructure development, industrial lifting, and more. Its combination of power, precision, and flexibility makes it a valuable asset for heavy-duty lifting tasks.
