SECTOR SPOTLIGHT Ӏ ALL TERRAIN CRANES
The battery pack enables
approximately five hours of emissions-free lifting, says Manitowoc. When the crane is connected to the grid, crane operation can be extended to approximately 20 hours, without compromising speed or capacity. This, it says, is more than enough functionality for a 150 tonne taxi crane and, when the day’s work is complete, the batteries are recharged while the crane is driven back to base, ready for the next working day.
ECO CRED “These new plug-in hybrid cranes deliver more sustainable lifting and boost owners’ environmental credentials,” said Florian Peters, senior product manager for all terrain cranes at Manitowoc. “They can drive to the job site using HVO fuel to power the efficient Mercedes-Benz engine and reduce car-bon emissions by up to 90% while simultaneously charging the batteries. Then, they can set up and use clean electricity to handle the lifting tasks. There’s also a massive reduction in noise pollution – a great advantage when operating in a city centre.”
STRONG AND RELIABLE Adopting this more sustainable power source has no negative impact on lifting performance. Structurally, the 60 metre main boom on the Grove GMK5150L-1e and 68.7 metre main boom on the GMK5150XLe are identical to the diesel models, as are the load charts. The cranes also retain Grove’s
Megatrak independent suspension system and disc brakes, with just minor tweaks to the driveline. The control system is
Manitowoc’s Crane Control System (CCS) with boom configurator mode and the MAXbase outrigger positioning system.
“Many cities and industrial
sites are placing increasingly strict environmental requirements on machinery, so there is a need to provide customers with options to help them achieve their commercial and environmental goals,” added Peters. “We expect a lot of interest in these hybrid cranes and are excited to unveil the GMK5150XLe at Bauma 2025.” For more from Peters on these
cranes see our exclusive interview starting on page 40.
Tadano’s new AC 5.250L-2
LONG BOOM Tadano has launched an upgraded ‘long boom’ version of its five- axle AC 5.250-2 all terrain: the AC 5.250L-2, which will also be showcased at Bauma. The AC 5.250L-2 has a
79-metre-long main boom, a maximum main boom extension of 30 metres, and a load moment of up to 736 tonne metres. This high load moment is achieved with a working radius of seven metres, a 13.5-metre-long main boom and a load weight of 105.2 tonnes. In addition, Tadano offers an optional heavy-lift attachment for even heavier loads up to 138.7 tonnes on the short boom with additional sheaves.
TAXI WORK The crane is well suited for use as a taxi crane, says Tadano. For example, in 10 x 6 drive format, it can travel between jobsites on 16-inch steel wheels whilst carrying a large amount of kit whilst still complying with 12-tonne axle load limits. This includes carrying items such as a 32-tonne Vario hook block and outriggers (with a total weight of less than 60
