New lithium-ion Unic mini crane offers zero emissions

Unic Cranes Europe introduced its latest all-electric model at the Bauma 2025 trade show, the Unic UM445 mini spider crane, a four-tonne capacity machine powered by lithium-ion battery technology.

Designed for lifting in confined, urban, and environmentally sensitive job sites, the UM445 offers a main boom lifting capacity of 4 tonnes, a maximum lift height of 11 metres, and a working radius of 9.8 metres. The machine also supports pick-and-carry operations.

The new UNIC UM445 spider crane made its debut at bauma 2025 in Munich.

A hydraulic tele-luffing jib extends the crane’s capability to a maximum lift height of 17.5 metres, a working radius of 15.6 metres, and a lifting capacity of 1.5 tonnes.

The UM445 is operated via a new Scanreco radio remote control with a colour display and real-time data feedback for increased precision. Powered by a lithium-ion battery, the crane offers “charge while in use” capability, zero emissions, and low noise levels for continuous operation in restricted areas. Features such as variable outriggers, a Pop-up column, adjustable-width crawlers, and an advanced auto-levelling function provide added stability and versatility for complex lifting scenarios.
