Depends on the angle and amount of pull you are exerting on the system.
The simplest way would be lift it with tram you have, tie the boom to the
tower, remove the tram. Clamp pulley to the mast above the mounting position
of antenna, run rope over it to the boom. Put tension on it, untie the boom
and lift it to the position and put boom clamps. You will have no problem
lifting it vertically up, very little bending moment on the mast.
