'World’s strongest’ land-based crane finishes electric testing

The SK6000 crane can now operate directly from grid power and offers zero-emission capability.

The tests used two 600kWh Battery Boxes to deliver 1,200kWh – the same output as 20 electric cars. The crane functions by plugging into a medium voltage network.

Batteries or hydrogen generators can power the crane as well. This provides functionality at more remote sites, with the breaks in between lifts providing the perfect opportunity to recharge.

At ports, ‘shore power’ connections that are typically used to prevent cargo vessels idling at port can additionally power the crane.

The electrification also means the crane can operate at reduced noise levels.

The crane is produced by Dutch logistics company Mammoet and the project was part-funded by a research and demonstration fund to develop zero-emission initiatives at construction sites - Subsidieregeling Schoon en Emissieloos Bouwmaterieel in the Netherlands.
