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 electrical 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. Since skid steer loaders are manufactured with regular and high flow hydraulic systems, it is contemplated for the present invention to have two embodiments, one embodiment with a pumping capacity suitable for use with the regular flow hydraulic system and the other embodiment with a pumping capacity suitable for use with the high flow hydraulic system. Applications may include, but are not limited to, placing concrete in hard to reach areas.
