Concrete holding hoppers make it possible to store one or more charges near the place of use.
To optimize the production of concrete, one or more concrete holding hoppers can receive concrete from the travelling bucket so that the bucket can return to the mixer to pick up the next charge.
Having several concrete holding hoppers will also make it possible to mix the colours of the concrete as concrete with different colours can be discharged into separate hoppers.
A chute can be mounted under the travelling bucket, but then operators must be ready to receive the concrete when the travelling bucket arrives.
