“We have noticed an increasing demand from our customers for emission-free lifting,” says Harold van Oss, general manager at M.J. van Riel. “Particularly on inner-city and densely built construction sites, emission-free work is becoming more and more common. “As a company, we believe it is important to continually innovate in our materials and to do business in a sustainable way. Therefore, it is our ambition to climb one step higher on the CO2 performance ladder and that requires continuous investment”.
Emission-free and low-noise lifting on the construction site
The MK73-3.1 is electrically operated 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. In addition, it is very manoeuvrable, which makes it ideal for inner-city areas and construction sites with little space.
Making the crane fleet more sustainable
“The MK73-3.1 is the next step in making our crane fleet more sustainable,” continues van Oss. “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”.
