Abstract:
A machine for lifting and moving heavy slabs includes two channels connected only by a cable. The channels are placed against opposite edges of a slab. Each channel has a lower flange which is beveled so that the flange will scoop under the edge of the slab when moved toward the opposing channel. The channels are moved by attaching the cable to one channel and pulling the cable upward from the sheave on the other channel. Further lifting of the cable lifts the channels and the slab for moving.
