The lock complex in Heumen connects the river Maas with the Maas-Waal canal situated to the west of Nijmegen. QuayQuipTS was engaged to design the large and small lifting wheels and related mechanical components for the Heumen ship lock and floodgate project.

All eight lifting wheels are made of high quality cast steel. The larger wheels have outer diameters of 3800mm and weigh over 25 tonnes. QuayQuipTS also supplied forged shafts and cast-steel bearing blocks. The components are installed at either end of the floodgate’s rotational axis, in both lifting towers.
