Five common values

Mammoet serves customers by moving large and heavy objects. Mammoet really excels when it helps its customers move time. By providing smart solutions, Mammoet safely and professionally moves deadlines forward, improves uptime and reduces the cost of ownership. It is the challenge of pushing boundaries, creating new possibilities, and accomplishing the exceptional that moves Mammoet as a team.

Shared drive moves Mammoet. The Mammoet team is made up of a group of dynamic and diverse individuals – individuals from different countries, cultures and backgrounds. We share a strong bond that arises out of shared principles: integrity and loyalty and a shared drive:


Love the work

Working at Mammoet is not just any other job. Here people share a deep commitment to the work they do and a desire to excel by building craftsmanship and dedicating their talents. We love the challenges of the industry and the equipment that comes with it. Across all disciplines, ages and cultures, one common theme is that we all have a sense of belonging to something bigger than ourselves; something that moves us.


Results count

We are willing to take on tremendous challenges. Our desire is to achieve things that nobody believed possible. For us, it is not just about accepting the challenge, but about delivering the desired results. We go the extra mile, and then the extra inch. Whether in safety performance, or bringing down environmental impact, in building teams, in getting a contract, or executing the job, in making a profit, it is the result that always counts. We move for results.


Take care

People, communities and the environment require care. We make safety a top priority, always and everywhere, so that after a day’s work everybody can return home unharmed. We treat people fair, with clear feedback and rewards for results. We contribute to the communities that we work in. From our position as an industry leader we will actively contribute to sustainability, in our own company, with suppliers and with customers. We move with care.


Perform as a team

Our customers demand excellent performance; and so do we. We believe excellent performance can only be achieved through team effort. Everybody is expected to take his role in the team and bring maximum contribution. In a team, diversity drives performance; people build on each other’s strengths and step up to compensate shortcomings. We move as one.


Be responsible

Mammoet is a big international company. This position brings the responsibility to set standards and drive development. In this company, everybody has a job to do. With each job come specific responsibilities. Everybody has to stand for his work and ensure it meets industry and Mammoet standards. Jointly we are responsible for a sustainable future of our company. We expect people to speak up when it is for the benefit of the company. We expect others to listen and act if required. We step up and take responsibility; we move.

From then to now

On May 13, 1807, Dutch entrepreneur Jan Goedkoop starts his own maritime company. Later that century, the Gebroeders Goedkoop launch towing operations from Amsterdam Harbor.


The Van Seumeren Kraanbedrijf crane rental business was founded. The family business would be pivotal in the growth and professionalization of the global market for heavy lifting and transport.


The companies Gebroeders Goedkoop and Van Wezel merged to former Mammoet Transport, the following year acquiring Stoof Breda, one of the leading Dutch heavy transport companies.


Mammoet develops a revolutionary container-sized Self-Propelled Modular Transporter (SPMT), now widely used industry-standard equipment.

ALE was founded by Roger Harries. A majority of its work was undertaken from Hixon, UK, providing transport and heavy lifting to the conventional power generation sector.


ALE opened a branch in Abu Dhabi, serving the oil gas, and power industries in the UAE. It would later establish key engineering innovation hubs in Breda and Madrid. 


Mammoet raised the Russian nuclear submarine wreck Kursk, using over 3,000t of tailor-made equipment.


ALE transported Concorde GBOAA from London to Scotland using SPMTs and a multi-purpose barge.


ALE launched the world's largest capacity land-based crane at the time, the SK190, which would go on to spawn the SK350 and SK10,000, with capacities of 5,000t and 10,000t respectively. 


The Mega Jack was launched. This system changed construction in the offshore industry, and holds the record for heaviest lift at 43,475t.


ALE makes its last acquisition - of Dutch offshore services firm Conbit - growing to its final size, employing around 1,800 people across 40 branches worldwide.


ALE completed a string of high-profile projects: the UK's heaviest crane lift at Earl's Court, London; the launch of the RSS Sir David Attenborough and roof installation at Mordavia Arena, 2018 FIFA World Cup venue.

Two legacies become one

Mammoet joined forces with UK-based engineered heavy lifting company ALE, forming the largest engineered heavy lifting and transport company in the world
