The Netherlands-based M.J. van Riel recently took the first Liebherr MK73-3.1 ‘Hybrid Power Concept’ mobile tower crane into operation. This 38.5-metre crane with a maximum lifting capacity of 6,000 kilograms is electrically powered and has a single motor, enabling it to operate in a low-noise and low-emission way. It can be easily powered by a 32 or 63 amp construction cabinet on site. It only takes 10 minutes to assemble, which makes this crane also useful for short deployments. The tower crane has an ECO mode and a built-in generator, which allows the crane to work at 100% capacity and speed at all times. With a total length of 13.80 metres, a width of 2.75 metres and a height of 4 metres, it is very compact.
Harold van Oss, General Manager at M.J. van Riel said: “The MK73-3.1 is the next step in making our crane fleet more sustainable. It is the smallest in the Liebherr range of mobile construction cranes. We currently have three more on order, which we expect to receive this year. We also ordered two more of its big brother, the electrically operated MK88-4.1. This brings the total number of MK88-4.1 models in our crane fleet to four. We also have a 6-axle Spierings SK1265-AT6 eLift on order. This is the largest mobile tower crane in the world which can operate 100% emission-free. This brings our total to 13 electrically-operated mobile tower cranes”.
