ABSTRACT OF THE DISCLOSURE
A jack for supporting a ceiling beam is provided and
consists of a pair of vertical sliding support members
operated by a winch mechanism with cable which allows one
person to set the beam. The jack will lift heavy loads
eliminating the need for a crane and more manpower. In a
modification the winch handle can be operated by a foot lever
on base of the jack.
