Suburban Tower Optimal Tilt

I am looking to design a tilt mechanism for an aluminum tower that is 48 feet tall. The antenna and rotating motor would weigh approx 55 lbs. The tower would either weigh 350 or 550 lbs. I would like to if it is possible to have a mechanism to lay the tower down with either a hand winch or motorized winch. I have the basic design on the picture just need to know the forces on the winch and the i beam support, no particular software

I need someone with a mechanical design background or mechanical engineering background to help with this project.
