Jacopa designs, manufactures and installs clarifier Copa® tank scraper bridges, which are suitable for all types of circular settlement tanks (clarifiers) with diameters from 5m up to 45m in 1m increments.

Jacopa can also carry out complete refurbishment of any type of existing scraper bridge.

The structures are designed to withstand all of the loads and stresses placed upon the bridges, and are manufactured to the highest of engineering standards. All superstructures and underwater assemblies are protected to customer specification.

Bridges are manufactured in steel, which can be finished to customers specification, or aluminium. Small bridges are manufactured using a beam structure. Larger bridges require a lattice or girder structure to provide the required strength without excessive weight.

Designs include rotary half bridges, standard half bridges, twin- and triple arm rotary machines, and hydraulic lift scrapers. Scraper blades are designed in a helical curve formation to maximise efficiency and sludge removal.

All rotating bridges can be fitted with channel cleaning systems, such as rotary brushes, pressure washers, chains and fixed brushes. Scum removal systems are also available.

The end carriage unit incorporates a small electric motor and gearbox. It is designed to give a peripheral speed of 1-2m/minute, depending on machine design.
