Lifting transformers up to 500 mm at difficult accessible locations. Commissioned by Mammoet, Holmatro supplied 85 ton aluminum cylinders and stacking rings.
Commissioned by: Mammoet
Mammoet is specialized in heavy lifting and multi-modal transport. Their specialty is transporting, shipping, installing (horizontal and vertical) and decommissioning large and/or heavy structures to and from any location, on both land and water.
A crane cannot always be used for lifting transformers for Mammoet. In case of poorly accessible locations and at locations where the transformer is placed on a gravel bed, the company had needed a lightweight and user-friendly solution.
Holmatro developed 85 tonnes aluminum cylinders (HAC 85 H 10.65) and stacking rings to lift and lock heavy structures like transformers up to a height of 500 mm without the help of filler blocks. Aluminum cylinders with a capacity of 75 tonnes and a stroke length of 130 mm were also supplied. These cylinders were integrated into the aluminum climb cassettes, developed by Mammoet.
Jaap Jan den Boer, project supervisor Mammoet, explains: “We regularly carry out projects for an energy producer where we have to replace 3 transformers. This means we have to move 6 transformers in a few days, according to a schedule agreed in advance with the customer”. He concluded, “Holmatro's lightweight aluminum cylinders significantly reduce physical labor, making work much more enjoyable, resulting in a positive effect on health, ergonomics and safety. But it also saves a lot of time. Holmatro's aluminum cylinders are also regularly used in other projects where there is no time pressure”.
Did you know aluminum cylinders are up to 50% lighter than steel cylinders? They are therefore easier to work with and better for your employees health & safety.
