ABSTRACT:
A portable tower or derrick which may be easily towed to a selected location and then erected by a single operator. While in the transporting position, the lower portion of the portable tower is supported by wheel assemblies mounted on at least two of the tower support legs. A pivoting tongue assembly is affixed to the tower at one end and may be coupled to a vehicle at the other end. The tongue assembly serves to support the upper portion of the tower during horizontal transport. A winch or other mechanical means is utilized to erect the tower by controlling the pivotal motion of the tower about the end of the tongue assembly. Once erected, horizontal sections of the tongue assembly may be utilized to ascend the tower.
