Kobelco 7045

The Kobelco 7045 Bio-Matic crawler crane represents a significant advancement in compact crane design, integrating Kobelco’s latest human engineering concepts for efficient and safe operation in confined urban environments. With a maximum lifting capacity of 45 tons at a 3.7-meter radius, this crane combines power with agility, making it ideal for a range of applications including clamshell work, vibration hammer operation, and strut erection and removal on congested city sites.

The 7045 features a six-section boom that extends to a maximum length of 48.77 meters, and with an additional jib can reach a combined length of 54.86 meters. The crane delivers high hoisting speeds of 70 m/min (main and auxiliary winches) and fast boom hoisting speeds of 68 m/min, reducing cycle times and increasing productivity.

A standout feature is Kobelco’s microcomputer-aided reaction sensor system, which transmits subtle load movement feedback directly to the operator’s controls, enhancing precision and safety. The crane’s compact tail swing radius of just 3.83 meters and wide operator viewing angle further improve maneuverability and visibility in tight workspaces.

Powered by a Mitsubishi 6D16-TE1 water-cooled, turbocharged, direct-injection diesel engine producing 114 kW (150 PS) at 2,150 rpm, the 7045 delivers the muscle needed for heavy-duty foundation and lifting work. Its large-capacity 60-ton class winch with 16-ton line pull enables efficient sheet pile removal and supports deep clamshell excavation up to four floors below ground on the first cable layer.

Kobelco has equipped the 7045 with a heavy-duty brake drum featuring heat-radiating fins, ensuring safe, seizure-free operation even during continuous high-load hoisting cycles. The crane is also designed for easy assembly on site and delivers smooth, stable ride performance comparable to a passenger vehicle.

Altogether, the Kobelco 7045 Bio-Matic sets a new benchmark in compact crawler crane design, combining innovative technology, operator-focused safety and comfort features, and powerful performance to meet the diverse demands of urban construction and foundation engineering projects.
