Transporting a product that hardens quickly and is tough to remove should it set has long been a problem for concrete suppliers, but McNeilus has worked hard on a new drum design that should eliminate some of the more common problems.
The composite Revolution drum was introduced in 2002, and offered a mass savings of over 2000 lb (905 kg) compared to traditional steel drums. The new changes make the Revolution even more efficient.
The new drum has been prepared to prevent concrete buildup as much as possible. Surface imperfections have been removed and 2-in (50-mm water channels now allow water to flow behind the fins for better mixing and less chance of concrete remaining in the drum. The exterior surface is now finished in a UV-resistant layer that is easier to clean. The finish contains a white pigment for easy graphic applications, saving costs associated with painting a metal drum.
