Apparatus for mounting power cylinders for driving piers

摘要

A device for use with a pier installation apparatus of the type employed in lifting and supporting a foundation is provided. A mounting beam assembly for mounting hydraulic power cylinders in a straddling position around a pier to be driven into the ground by the installation apparatus. The beam assembly is a planar member having a central opening for receiving the pier therethrough. It is comprised of opposing plate members beneath which the hydraulic cylinders are mounted. The plate members each have an opening which allows passage of the piston rod through the hydraulic cylinder. Alternatively, the beam assembly may be comprised of a unitary plate member having a lateral opening at a side edge. The mounting beam assembly allows for lateral placement around a pier in the installation apparatus, and may be completely disassembled for quick and efficient installation and removal.
