Device for performing maintenance on a height-adjustable, powered submersible device on a biogas facility fermentation container

摘要

During the normal operation of a submersible appliance, a floor opening (9) in a fermenter vessel has a gas-tight cap formed by a platform (15) and an adjacent mast housing (16) to overlap the surface of the platform. In the mast housing there is an upper mast part (8) for a vertical guiding mast including a height-adjustment device with a cable pulley (11), a dedicated hauling cable (12) and a drive unit.
