Raider 4

Unitized Concrete Plant

The CMI Raider 4 is a concrete batching and mixing specialty plant that combines all of the quality control advantages of central-mix, the economy of complete factory assembly and the convenience of mobility in a single unit.

The 4.5 yd³/hr (3.4cm³/hr) batch size offers quality concrete in quantities sufficient for medium sized construction projects, wet precast or ready-mix operations.

Low power requirements allow use of line power or a generator set.
