Norwegian crane rental company Asle Skoveng kranservice has taken delivery of a new 50 tonne Liebherr LTC 1050-3.1 E hybrid city type All Terrain crane.
The company, based in Skedsmokorset on the north side of Lillestrøm - to the north east of Oslo - made a contract with Liebherr around two years ago in which it agreed that it would purchase the first five LTC 1050-3.1 E off the production line. The company welcomed the new crane with an open day for customers, local dignitaries and the local press.
The new crane, which was launched last April, features a 72KW electric motor and control system, alongside the standard six cylinder diesel. The two power units use the same hydraulic pumps, and the operator can switch between diesel and electric power for crane functions. Once on site, it ideally plugs into a 125 Amp mains power supply to fully match the performance of the diesel mode, but it also operates well enough on a 63 Amp supply.
The electric version of the LTC 1050-3.1 features the 36 metre six section telematic boom, rather than the new shorter cable extended boom, topped by a 7.5 to 13 metre bi-fold swingaway extension for a maximum tip height of 52 metres, with up to 60 degrees of offset. The crane also has an elevating cab taking the operator to a height of 7.8 metres, Variobase outrigger set up and monitoring, and all wheel steer and drive.
Chief executive Lars Christian Steen said: “This machine is predicted to save around 20 tonnes CO2 each year, and we have four more machines coming, that will mean that by the end of the first quarter of next year, we will be able to cut 100 tonnes of CO2 a year, just with these LTC cranes. We are receiving more and more demand for zero emission machines on job sites, especially within city limits, and we are positioning ourselves for the future. We aspire to be a company that is associated with green technology and are striving to be a pioneer in this field. To amplify this, we have just agreed on delivery of a new MK-88, which will mean the that by the time all of the new cranes are delivered, half the cranes in our fleet will have the possibility to run on electricity.”
“We have also been fortunate to test a prototype of Liebherr’s new mobile battery pack, the Liduro LPO80 which we can use with either the MK88-4.1 or LTC1050-3.1 E, allowing us to work on remote sites with zero emissions.”
