Abstract
A lifting device that can effectively lift a variety of objects and enhance portability. The lifting device provides demountable portability that enables easy adaptation of the invention for objects of varying size. This adaptability provides a universality that minimizes the number of lifting devices need. The demountable nature of the invention also aids in efficient storage. Generally described, the lifting device includes a mast separable into a plurality of sections and a pulley supported by a first section of the mast. A dolly that supports the mast includes one or more transport structures for movably supporting the lifting device. An actuator is mounted on a second section of the mast. A carriage captured on the mast is configured to slide along the mast and directly or indirectly support an object to be lifted. The lifting device also includes a belt with a first end and a second end. The first end attaches to the carriage and the second end attaches to the actuator so that the belt extends over the pulley. The actuator selectively reels the belt in and out when the belt is positioned over the pulley. This causes the carriage to move up and down along the mast. The belt is…
