The most powerful mobile tower crane ever built
With a jib length of 42 or 50 metres and a lifting capacity of as much as 5.5 tonnes at the tip, this crane delivers powerful performance. The SK2400-R is transported on just two trailers: one for the crane and one for the counterweight and tracks. Uniquely, the crane picks up its own counterweight and crawler parts, making an additional crane unnecessary. Of course, this Spierings crane is also equipped with the eLift system, for emission-free work on any site.
