    摘要： The tower assembly is used in construction work for supporting a load such as girders or concrete form assemblies at varying elevated positions above the ground surface during the building of highway bridge structures and the like and comprises a series of vertically stacked tower sections. Each tower section has four corner posts which in adjacent tower sections are releasably connected together in an end to end relation to provide a desired tower height. The corner posts on the top and bottom tower sections have independently linearly adjustable extension units to accommodate, respectively, varying load engageable surfaces and an uneven ground surface. A frame structure is connectable to each adjacent pair of corner posts in a tower section at selected positions longitudinally thereof to vary the spacing between adjacent pairs of corner posts in accordance with the dimensional requirements of the load to be supported by the tower assembly.
