RAMEX concrete mixing buckets are designed for efficient concrete mixing and pouring, especially in hard-to-reach areas. The bucket can be used as a standard bucket to load concrete components such as sand, gravel, and aggregates directly into the mixing chamber. Thanks to the upper grill panel, cement and other additives can be added easily and safely during operation. The mixing shaft is driven by a hydraulic motor connected via a durable chain-sprocket transmission system. A hydraulically operated discharge hatch allows controlled unloading, and an elastic discharge tube can be connected for precise concrete pouring in confined areas.
