ABSTRACT:
This invention is a tool apparatus operable to aid in assembling and disassembling of large, rotational sprinkler systems for crop irrigation purposes. The tool apparatus function is to present the tools and the structure for readily maneuvering the elements of the respective irrigation sprinkler system. More particularly, the tool apparatus includes (1) a basic support assembly resembling a flat bed trailer to be pulled behind a truck, tractor, or the like; (2) a tower support assembly connected to the basic support assembly; (3) a collapsible tower assembly connected to the tower support assembly and pivotal relative thereto to be accessible to irrigation pipe members; (4) a tool and parts bin assembly to contain and separate the tools and parts needed for use on the sprinkler system; (5) a tool power assembly having an air compressor assembly to provide air power for tool members; and (6) a personnel support assembly operable to support one in an elevated position to connect and disconnect adjacent irrigation pipe members. The tower assembly is foldable from a transport position to an upright, usage position and includes two (2) winch assemblies operable to move the pipe members as required. All the aforementioned elements of the tool apparatus cooperate to present the structure necessary to effectively assemble and disassemble the irrigation sprinkler system with a minimum amount of effort.
