RC

The RC type is commonly used for rectangular tanks and has the specific function of conveying the sludge gathered on the tank bottom to a lateral hopper and clean the water surface from any floating substances, conveying them to a lateral channel.
The chain scraper consists of a gear motor control unit, a drive shaft placed on the final end of the tank with two crown gears at their extremities, two driving chains, three or more idle shafts complete with toothed crowns, scraping blade, secured to the pulling chain, made of press-bended metal sheet and complete with adjustable rubber.
The gear motor motion is transmitted to the shaft which, by means of two lateral crowns, puts in motion the two gearing chains. On the opposite side there is the transmission unit which serves for the chain tightening; moreover specific guides keep the chain in the right position and avoid any deflection due to the own weight and the scrapers.
The peculiarity of this scraper consists in the double function of the scrapers; in fact, during the lower run, they push the sludge into the recovery hopper while during the higher run they convey the floating materials into the lateral channel. A chain scraper, which only cleans the tank bottom or surface and complete with two totally independent scrapers can be supplied on request, for special requirements. On request it is also possible to combine the two models and have the tank bottom and surface cleaned by two completely independent scrapers.
The standard construction is in carbon steel. On request, the construction in stainless steel or aluminium or in plastic material is possible.
