Concrete recycling systems from Liebherr

Concrete pumps cannot discharge residual concrete or cleaning water into the regular truck-mixer hopper because of the low discharge point on the vehicle. Liebherr therefore supplies a low-level loading hopper with conveyor. Material can then be discharged by the concrete pump and transferred to the recycling plant without diffi culty.
