About us

We help the world to grow safely, efficiently and move to a more sustainable future.

Mammoet provides solutions to any heavy lifting or transport challenge. We aim to develop long-term relationships with our clients in order to understand their businesses and challenges. By working closely with our partners, we realize the most efficient and cost-effective approaches.

We have a unique global network and an unparalleled fleet of equipment. Our extensive engineering expertise and high quality and safety standards deliver value to a wide breadth of industry sectors and projects. Clients trust us to help them achieve feats that were once considered impossible, and we have often broken records in doing so.

Wherever there is growth, there is need for energy, power, raw materials, infrastructure. Helping to meet those needs is a World in itself. It is the World of Mammoet.

In this World, it is our purpose to lift, transport, install and decommission big objects so that our customers can grow and maintain their production capacities and infrastructures in the safest and most efficient ways possible.

We believe that our activities significantly help customers in their growing need for productivity and continuity, through creative engineering, careful planning, and safe execution. For that, we continuously raise the standards of our profession.

Yet we also believe that our contribution stretches beyond engineered heavy lifting and transport. We are part of an industry that provides meaningful jobs to hundreds of thousands of people and significantly affects societies everywhere. We want our employees to enjoy their working lives and grow as professionals and persons. We want our performance to be in harmony with the communities we may work in and interact with. And we strive to, ultimately, eliminate any negative impact on the environments we operate in.

The logistic challenges in these industries are growing daily. Factors such as remote locations, harsh climates, and a strong emphasis on the environment are constantly driving us towards smarter and safer solutions.

For over two hundred years, we have been known for the unique capability of our state-of-the-art equipment. But it’s the trust of our clients that has brought us where we are today. Their confidence inspires 7,000 Mammoet professionals to give it their all each day and truly make a difference in projects all over the world.
