Benefits of technology

[0007]As a climber climbs the tower, the climber may tie-off his / her safety harness to the tie-off openings in the brace plates. The absences of diagonal members extending between the leg members of the leg of the tower make it easier and safer for the person to climb the tower.
[0008]It is therefore a principal object to provide an improved leg for a self-supporting tower.

Abstract

A leg for a self-supporting tower comprising a plurality of upstanding leg members having upper and lower ends. A plurality of vertically spaced-apart and horizontally disposed brace plates are secured to the leg members and extend therebetween. The brace plates have a pair of spaced-apart tie-off openings formed therein which enable a tower climber to tie-off the climber's safety harness thereto. The brace plates have an elongated wind load reducing slot formed therein between the tie-off openings. The leg is devoid of any diagonal braces extending between the leg members thereof thereby making it easier and safer for a climber to climb the tower.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a leg for a self-supporting tower. More particularly, this invention relates to a leg for a self-supporting tower with the leg including a plurality of upstanding, spaced-apart leg members which have a plurality of vertically spaced and horizontally disposed brace plates secured to and extending therebetween with each of the brace plates including a generally vertically disposed plate portion and with each of the plate portions having a pair of tie-off openings formed therein and an elongated wind load reducing slot formed therein.[0003]2. Description of the Related Art[0004]Many types of legs for self-supporting towers have been previously provided for use in supporting antennas, transmission lines, etc. Usually, each of the legs of the prior art self-supporting towers include a plurality of leg members having horizontally disposed and diagonally extending support braces in the form of pipes o...
