Design and manufacturing of an ATEX jib crane, trolley and hoist set dedicated to the Reyran sewage treatment plant gasometer

Customer’s challenge

Located on the banks of the Reyran River in Fréjus (France), the Reyran STEP (Sewage treatment plant) has been treating sewage from the municipalities of Saint-Raphaël and Fréjus since 1970. The Reyran sewage treatment plant is in 2017 equipped with a digester designed to transform part of the plant's sludge into green energy. The aim is to produce 500,000 m³ of biogas. The gas is stored in a gasometer located near the plant's digester. 

The devices used to purge the gasometer are gathered in a pit and require the installation of an ATEX-compliant lifting device to ensure maintenance.
