Compact crane MK 140-5.1E

adjustableboomluffing jib

Overview
The MK 140-5.1E mobile construction crane is a five-axle, compact mobile crane delivering lifting capacities and operating ranges typically found in higher axle classes. The Hybrid Power Concept enables operation from site power and the crane is approved for HVO fuels, preparing it for low-emission applications.

Key features

• Quickly ready: Erects within minutes and is operational after only a few actions.
• Urban operation: Multiple steep boom positions allow safe work close to buildings and confined edges at the push of a button.
• Fully electric drives: Winches and drives are powered by electric motors for low-noise, low-emission and efficient operation.
• Unique Vario Jib: Converts from trolley jib to luffing jib within minutes operated by one person.
• Vario Jib performance: In luffing-jib mode achieves a hook height of 94.4 m, a radius of 65 m and a tip load up to 1 t.
• Compact manoeuvrability on 5 axles: Steering programs enable precise manoeuvring in tight urban spaces.
