• Benford dumper parts, for PT, PS and HD models such as the PT9000 and HD1000

Benford, Terex and Mecalac: one line of dumpers

The Benford dumper range dates back to 1953. Terex bought Benford in 1999 and rebadged the machines Terex, and Mecalac took over in 2017 and still builds them in Coventry. The design carried on under each badge, so many parts fit all three, and the same part can appear in each make's range. Our guide Benford, Terex and Mecalac dumpers: do the parts fit? sets out the model families.
