Concrete placer attachment for skid steer loaders

摘要

A concrete placer for attachment to a skid steer loader which runs only off the auxiliary hydraulics and electric power of the skid steer loader. The concrete placer comprises a hopper, a concrete pump frame, two concrete pumping cylinders, and a small hydraulic cylinder and swing valve assembly which together control movement of a swing valve to alternately receive concrete from each of the two concrete pumping cylinders and discharge it from a porthole in the hopper.
