The Liebherr MK 140-5.1 is a versatile mobile construction crane specifically designed to meet the demands of urban building sites and complex infrastructure projects. With a maximum lifting capacity of 8 tonnes and an impressive maximum hook height of 65 metres (extendable to 94.4 metres with optional lattice jib heads), this crane excels in confined spaces where conventional tower cranes cannot operate. Its “taxi crane” concept allows for multiple job site deployments in a single day without the need for additional logistical support, while the compact dimensions and flexible outrigger widths ensure effortless setup even in tight inner-city environments.

At the heart of the MK 140-5.1 is a 400 kW (544 PS) Liebherr diesel engine and a fully electric crane operation with hybrid power supply, enabling quiet, emission-free lifting when required. The crane features an innovative VarioJib system that offers both trolley and luffing modes for maximum flexibility, while smart assistance systems such as LoadPlus and TrolleyPlus automatically increase lifting capacity when needed. The height-adjustable elevating cabin provides operators with perfect visibility over the site, and the self-ballasting capability eliminates the need for auxiliary lifting equipment. Combining exceptional mobility, rapid setup times, and advanced automation, the MK 140-5.1 is the ideal solution for modern construction projects where efficiency, safety, and environmental responsibility are paramount.
