German rental company Wilhelm Bruns has taken delivery of two Grove All Terrain cranes - a 100 tonne GMK4100L-2 and a 250 tonne GMK5250XL-1 - for its operation in Lüneburg in Lower Saxony.
Both units arrive on site
The four axle GMK4100L-2 features a 60 metre seven section main boom, topped by a 9.7 to 16 metre hydraulic luffing bi-fold swingaway extension, an additional eight metre insert is available that can be installed between the boom nose and swingaway, for a maximum tip height of 89 metres. The crane carrier has an overall width of 2.55 metres, and an overall length of 11.18 metres. It can carry up to 6.8 tonnes of its 26 tonnes maximum counterweight within 12 tonne axle loads, or 21.2 tonnes with the UK's maximum 16.5 tonne axle loads, including the all wheel drive option. Power comes from a fuel efficient Stage V Mercedes diesel, with ECO mode, and 100 percent HVO fuel compatibility.
The 250 tonne GMK5250XL-1
The five axle GMK5250XL features an eight section 78.5 metre main boom topped by an 18 metre bi-fold swingaway extension that can be extended to 34 metres with additional inserts. Features include Grove’s Maxbase variable outrigger setup, Megatrak suspension with all wheel steering and twin lock boom pinning system. Power comes from a single HVO ready Stage V Mercedes diesel which is said to offer a 30 percent reduction in fuel consumption compared to previous power units.
Established as a construction company in 1924, Bruns purchased its first crane - a Krupp 22 GMT All Terrain crane - in 1967. Alongside sister company Alex Grund, which it acquired in 2002, it has a combined fleet of 14 cranes with capacities from 40 to 400 tonnes operating from its locations in Lüneburg and Hamburg. The company also runs a fleet of heavy haulage vehicles as well as a number of aerial work platforms.
