First job for Liebherr’s taxi crane
By Niamh Marriott15 October 2021
The new Liebherr MK 73-3.1 mobile construction crane is compact, measuring just 13.80 metres in length, 2.75 metres in width and 4 metres in height, and well suited to smaller construction sites.
The crane offers lifting capacity of 2,000 kilograms at maximum radius, which can be increased up to 2,800 kilograms depending on the luffed position.
On its first job in Haarlem, the Netherlands, the taxi crane lifted insulated sheeting to the roof of a historic building, manoeuvring through the densely built-up street where 70 new flats are being constructed. Due to its small size, the crane could be positioned in close proximity to the building and the projecting edges of the angular building didn’t pose a problem.
“The crane is really compact and I like the fact that I can also operate it using site power,” said crane operator Tim Hoekstra (Koninklijke Saan B.V.) “For tight locations like here in Haarlem and Amsterdam, where I work a lot, the variable support widths are ideal for assembly.”
The MK also features smart assistance systems such as Load Plus and level luffing in luffed positions.
The MK 73-3.1 can be operated electrically on site or powered by its integrated drive unit. Operation is quiet and emission-free in electric mode.
Some 50 kilometres to the south-west, in the Hague, Voorburg district, another Liebherr MK 73-3.1 was used to move painting platforms. The platforms weighed 800 kilograms.
The parts, weighing 800 kilograms, were located at a height of 20 metres on the roof of a residential building and needed to be moved back a further 30 metres.
The painting platforms couldn’t be seen from the ground but modern camera systems supported the crane operator during the lifts.
The mobile construction crane, which is part of the fleet belonging to crane company Nederhoff B.V., worked on the site for roughly a day.
It is designed for one-man operation and is ready to lift in around ten minutes.
