Crane Overview: The new MK 73-3.1 from Liebherr

MYCRANE

21.10.2021


The smallest of Liebherr’s mobile cranes has been designed to excel in tight construction sites and densely built-up areas. The MK 73-3.1 measures 13.8m in overall length, 2.75m in width and 4m in height and is perfectly adapted to work in inner-city projects. 

The mobile construction crane is said to be particularly well suited to smaller sites and short assignments, such as a historical residential redevelopment in Haarlem, very near to Amsterdam. More than 70 new flats are being created in the densely built-up city centre following the relocation of the district court.  

It was the crane’s task to lift insulated roof sheeting and was able to be positioned in close proximity without the projecting edges of the angular building posing a problem.  

Restricted space on site, tight access routes and the need for the lowest possible environmental impact were all challenges that crane rental company Koninklijke Saan B.V. overcame, thanks to the MK 73-3.1.  

“The crane is really compact and I like the fact that I can also operate it using site power,” says Tim Hoekstra who drove and operated the mobile construction crane that day. “For tight locations, 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 and can also be operated electrically on site or powered by its integrated drive unit.  Operation is extremely quiet and emission-free in electric mode.
