See how to use GRABO to lift heavy stone slabs into place. GRABO is positioned onto the center of a stone slab. The worker simply lifts the stone slab into place using one hand, with the other guiding the slab into place. Checking if the slab is now placed evenly and firmly, the GRABO is then released from the slab by the worker. A much more efficient and safer way to work is shown, rather than lifting with both hands and risking injury.
