Chapter 2: General Information
Elevator Guy Bracket Position
1. When possible, the elevator leg should be centered within the tower so that the wind load transmit-
ted to the tower is distributed equally between the two parallel sides of the tower.
2. If the elevator guy is outside the tower, when possible, the leg should be centered between the two
nearest columns of the tower so that the wind load is distributed to the tower equally.
