ABSTRACT:
A placement and orienting apparatus for a pump and water passing pipe assembly includes a wheeled trailer supporting the pump and water passing pipe assembly; an upper frame structure; a lower frame structure; a turntable bearing assembly positioned between and interconnecting the upper and lower frame assemblies and permitting rotation of the upper frame structure relative to the lower frame structure; a motor drivably connected to one of the upper frame structure, the lower frame structure and the turntable bearing assembly to rotate the upper frame structure and the trailer relative to the lower frame structure and the ground; and at least one upright hydraulic cylinder having a cylinder lower end connected to the upper frame structure and having a cylinder upper end connected to the trailer to drive the upper and lower frame assemblies downwardly together from the trailer so that the lower frame structure makes contact with the ground and elevates the trailer from the ground.
