Telescopic support tower

A tower for supporting a heavy load from a tower foundation comprising at least two elongated, telescopically associated tower sections including a lower tower section supported vertically on said tower foundation and an upper tower section telescopically nestable in relation to said lower tower section, a lift mechanism interconnecting said lower tower section and said upper tower section, said lift mechanism including a plurality of generally parallel vertical jackrods and crawler jack assemblies interconnecting said lower tower section and said upper tower section to move said upper tower section vertically to an elevated position in relation to said lower tower section, an upper end portion of said lower tower section and a lower end portion of said upper tower section each including peripheral mating wedge assemblies which are interconnected to retain said upper tower section in said elevated position and in vertical alignment with said lower tower section.

A tower for supporting heavy loads above a tower foundation which comprises a plurality of elongated tower sections including at least an outer tower section and an inner tower section nested in a vertical telescoped position with said inner tower section nested within said outer tower section, said outer tower section having a lower end mounted on said tower foundation to enable the nested vertically telescoped tower sections to be extended vertically, said inner tower section supporting said heavy load when nested in said outer tower section, and a lift mechanism interconnecting said outer and inner tower sections to telescopically raise said inner tower section and said heavy load to an extended tower height.

A tower for supporting a heavy load from a tower foundation comprising at least two elongated, telescopically associated tower sections including a lower tower section supported vertically on said tower foundation and an upper tower section telescopically positioned in said lower tower section, a lift mechanism interconnecting said lower tower section and said upper tower section, said lift mechanism including a plurality of generally parallel vertical jackrod and crawler jack assemblies interconnecting said lower tower section and said upper tower section to move said upper tower section vertically to an elevated position in relation to said lower tower section, a lower end portion of said upper tower section including a plurality of peripheral low sway rollers guidingly engaged with a peripheral surface of said lower tower section, said lower tower section including a plurality of upper sway rollers to guide relative vertical movement of said tower sections.

The method of erecting a tall support tower having a plurality of elongated telescopic tower sections above a tower foundation comprising the steps of mounting an outer tower section in vertical position on said foundation, vertically inserting an inner tower section downwardly into said outer tower section, elevating said inner tower section vertically to an expanded tower height, limiting vertical movement of said inner tower section by coacting wedge structures on the upper end of said outer town section and lower end of said inner tower section and extending fastening members through the coacting wedge structures to secure said tower sections in expanded tower height.

A tower for supporting heavy loads above a tower foundation, said tower comprising a plurality of elongated tubular tower sections including at least a lower tower section and an upper tower section each including a substantially cylindrical peripheral wall, said tower sections being telescopically nested and disposed in a generally vertical position, said lower tower section having a lower end supported from said tower foundation to enable said upper tower section to be extended vertically, said upper tower section supporting said heavy load at an upper end thereof when nested in said lower tower section, and a lift mechanism interconnecting said lower and upper tower sections to telescopically extend said upper tower section and lift said heavy load to an extended tower height, coacting structures on a lower end of said upper tower section and an upper end of said lower tower section, said coacting structures being rigidly connected when said upper tower section is vertically extended by fasteners interconnecting said coacting structures.

A tower for supporting heavy loads above a tower foundation, said tower comprising a plurality of elongated tubular tower sections including at least a lower tower section and an upper tower section each including a perimeter structure, said tower sections being telescopically nested and disposed in a generally vertical position, said lower tower section having a lower end supported from said tower foundation to enable said upper tower section to be extended vertically, said upper tower section supporting said heavy load at an upper end thereof when said tower sections are nested and a lift mechanism interconnecting said lower and said upper tower sections to telescopically extend said upper tower section and lift said heavy load to an extended tower height, coacting connecting structures on a lower end of said upper tower section and an upper end of said lower tower section, said connecting structure being matingly and rigidly engaged when said tower sections are vertically extended, and fasteners interconnecting said connecting-structures when said tower sections are extended to tower height.
