Described is a hoisting apparatus comprising a temporary support that is adapted to be secured to a pair of vertically disposed, permanent threaded rods suspended from a ceiling. A pair of temporary threaded rods extends vertically downward from the temporary support. A permanent support that is desired to be lifted and secured in an elevated position is engaged with the pair of temporary rods, and a pair of lifting mechanisms is connected to the permanent support and engages with the temporary rods. The lifting mechanism is adapted to raise the permanent support along the length of the temporary rods, and as the permanent support is lifted, it comes into contact with the permanent rods. Once the desired height is reached, the permanent support can be secured to the permanent rods. The temporary support, the pair of temporary rods, and the lifting mechanisms can then be disassembled and removed.
