Roller boxes are designed to carry the welded pipeline of a stinger and support it into the water. For this reason they have to be adjustable in different height positions, according to the calculated allowable bending curve. Based on the concept of its standard range of aluminium cylinders, in cooperation with its customer, Holmatro designed an easy to handle aluminium pulling cyclinder, due to its considerably lower weight. The height setting of the roller boxes is now executed more conveniently and safely.
