Kobelco MK650

The Kobelco MK650 is a 65-ton class lattice boom truck crane that offers a well-balanced combination of lifting capacity, mobility, and functionality for a wide range of applications. It has a maximum rated lifting capacity of 65 tons at a load radius of 3.0 meters. The maximum boom length is 33.0 meters, with the main boom extending to 5.6 meters in its minimum configuration. The crane has a maximum hook height of 31.9 meters and a working radius of up to 30.1 meters, making it versatile for medium- to large-scale lifting tasks.

In terms of hoisting capabilities, the crane is equipped with a high-performance winch system, offering a hoisting speed of 120 meters per minute under full load, and a secondary winch with a speed of 72 meters per minute. The maximum line pull for the hoist is 68.6 kN, and the rotation or slewing speed of the superstructure is 3.75 rpm. The crane’s boom elevation is hydraulically controlled, allowing smooth and precise lifting operations, and the boom is designed with an all-purpose lattice-type structure for enhanced stability and reduced weight.

The Kobelco MK650 features a robust six-axle carrier with an 8×6 drive configuration, ensuring excellent mobility on the job site and road. The vehicle’s top speed is 39 km/h, and it has impressive gradeability of 20% in high gear (11.3 degrees) and 50% in low gear (26.6 degrees). The suspension system is fully hydraulic with spring dampers to handle different terrain types. The crane has a total length of 12.4 meters and a width of 3.07 meters, making it a compact yet powerful mobile crane.

Powering the MK650 is a 12.913-liter engine producing 330 kW (approximately 449 PS) at 1,800 rpm, allowing for efficient travel and operational speeds. The engine complies with modern emission standards, ensuring it operates with lower environmental impact. The fuel tank capacity is 355 liters, providing adequate range for extended use in remote work environments.

The crane’s hydraulic system is powered by a three-stage pump with variable displacement, ensuring smooth and efficient operations, especially during lifting and slewing tasks. Additional features include a hydraulic brake system with a foot-operated control and a two-stage air brake system for the wheels, ensuring safety and reliability when operating on various terrains.

The Kobelco MK650 is designed to handle demanding construction tasks while offering excellent mobility, making it suitable for infrastructure projects, building construction, and heavy lifting applications in urban or remote locations.
