Mammoet Completes BMU Replacement Project in The Hague Using Liebherr LTM 11200
30-Second Takeaway
Mammoet has successfully completed a complex BMU replacement project in The Hague, lifting components up to 3,500kg using a Liebherr LTM 11200 mobile crane. Despite limited space and nearby infrastructure constraints, the project was delivered safely with minimal disruption through careful planning and efficient crane deployment.
Mammoet completes complex urban lifting project in The Hague
Heavy lift specialist Mammoet has completed the replacement of roof-mounted Building Maintenance Units (BMUs) on two Dutch government buildings in The Hague.
The project, delivered in collaboration with Façade Access Solutions, part of the Alimak Group, involved lifting and installing multiple components ranging from 200kg to 3,500kg.
Liebherr LTM 11200 enables efficient single-position lifting
A key element of the project was the use of a Liebherr LTM 11200 mobile crane, equipped with a Y-frame system to enhance lifting performance and stability.
The Liebherr LTM 11200 provided up to 180 metres of lifting capability, allowing the crane to operate from a single position while servicing both buildings. This eliminated the need for crane relocation, significantly reducing disruption and improving overall project efficiency.
Its compact footprint also proved essential for working within the confined conditions of the city centre.
Overcoming tight urban constraints
The project presented several logistical challenges, including extremely limited working space and the presence of surrounding infrastructure such as a nearby viaduct. To manage these constraints, lifting operations were carefully organised into defined zones, ensuring an efficient workflow throughout the installation process. Components were installed in a planned sequence, enabling simultaneous assembly on the rooftops, further optimising project timelines.
Minimising disruption in a busy city centre
Given the project’s location in a central government district, minimising disruption was a priority. Road closures were limited to just one day, while the ability of the Liebherr LTM 11200 to handle all lifts from a single setup helped avoid additional traffic and logistical complications. This approach allowed Mammoet to maintain operational efficiency while respecting the constraints of a busy urban environment.
Strict safety measures implemented
Comprehensive safety protocols were implemented throughout the project, including the use of fixed lifting points, adherence to low wind speed limits, and the installation of crash decks to protect the buildings. Despite the complexity of working in a densely populated political centre, the project was completed safely and efficiently.
Demonstrating expertise in urban heavy lifting
The successful completion of the BMU replacement highlights Mammoet’s capability in delivering complex urban lifting projects, particularly in environments where space, safety, and logistics must be carefully balanced.The use of the Liebherr LTM 11200 played a central role in ensuring precision, efficiency, and minimal disruption throughout the operation.
