A lifting pole assembly configured for removable attachment to a tower comprising a lifting pole, a bottom bracket assembly, a top bracket assembly and vertical tilt means. The lifting pole has a lower end and an upper end. The bottom bracket assembly includes a first end attached to the tower and a second end attached to the lifting pole proximal to the lower end thereof. Similarly, the top bracket assembly includes a first end attached to the tower at a position above the point where the bottom bracket is attached to the tower and a second end attached to the lifting pole at a position above the point where the bottom bracket is attached to the lifting pole. The vertical tilt means enables the lifting pole to pivot in the vertical plane about a point proximal to the connection between the bottom bracket and the lower end of the lifting pole. Horizontal pivot means for enabling the lifting pole to pivot in the horizontal plane relative to the tower may also be provided. The horizontal pivot means includes a bottom mount bracket of the bottom bracket assembly having a first end removably attached to the tower and a second end pivotally attached to a bottom swivel pivot bracket by a bottom swivel bolt connection. |
