Kobelco 7080 Load Chart PDF + Specifications

The Kobelco 7080 is a heavy-duty 80-ton capacity hydraulic crawler crane engineered for high-performance lifting and mobility. The crane offers a maximum lifting capacity of 80 metric tons at a 4.0-meter radius. It comes equipped with a main boom that extends up to 57.91 meters and can be further enhanced with jib and luffing jib configurations to reach a total length of 79.25 meters. The boom and jib sections are built using welded tubular high-tensile steel chords for maximum strength and durability.

Powering the crane is a Mitsubishi 6D22CT diesel engine delivering 245 PS (180 kW) at 2,000 rpm, with a torque of 105 kg-m at 1,200 rpm. The hydraulic system is robust, comprising three plunger pumps and two gear pumps, controlling hoisting, slewing, and travel functions with impressive precision. Hydraulic pressures are maintained at 280 kg/cm² for hoisting and 250 kg/cm² for swing operations. The reservoir capacity is 300 liters, ensuring consistent fluid supply for all operations.

The hoisting system includes large-capacity main and auxiliary drums, each powered independently by dual hydraulic plunger motors through planetary reducers. Both hoists support 26 mm wire rope, offering speeds up to 90 m/min. The luffing jib system supports up to 15 tons, with jib lengths reaching 35.05 meters and an overall reach of up to 79.25 meters with the tower jib configuration.

For mobility, the 7080 is equipped with a two-speed travel system for enhanced traction and breakout force. It utilizes wide 900 mm crawler shoes, enabling a high travel speed of 1.4 km/h and excellent ground contact. The Trans-Lifter system allows for simplified side frame removal and trailer loading, making transportation efficient.

The operator cab is designed for full visibility and ergonomic control, featuring sliding windows, a full-suspension adjustable seat, and all-around operational instruments. Control levers for travel, hoisting, slewing, and speed selection are within easy reach. Safety systems include multiple hydraulic brakes, drum locks, over-hoist protection, and optional load moment limiter.

With its rugged construction, powerful lifting capability, and versatile configurations, the Kobelco 7080 is a reliable crawler crane choice for infrastructure, construction, and heavy lifting projects.
