Abstract
Currently, a drywaller on the ground physically lifts the 100+ pound sheet of drywall up to the person on the scaffold, who then has to lift/pull the 100+ pound sheet of drywall up onto the scaffold to hang on the wall. Both people must use their arms, shoulders and back to lift the drywall, and the man on the scaffold sometimes uses his foot to slide the drywall up onto the scaffold. The DSR eliminates this unsafe lifting procedure by providing a rolling mechanism to roll the sheet of drywall instead of lifting. It takes most of the heavy weight of the drywall off the workers, making it safer and easier, which may reduce the number of arm, shoulder, back and foot injuries from manually lifting the heavy sheet of drywall from the ground up onto the scaffold. It is an inexpensive way for drywall companies to more likely than not reduce the number of workplace injuries and worker's compensation claims.
Claims
1. A roller to lift heavy materials, such as drywall or plywood, from the ground up on to a scaffold, comprising a nylon washer, roller, push ring cap, shaft, disc, and spacer, such that there would be less strain on the worker's body by rolling the material instead of lifting it.

DETAILED DESCRIPTION OF INVENTION
[0115] The drywall scaffold roller lift (DSR) is a tool that every person who hangs drywall for a living needs for moving drywall from the ground onto a scaffold above the ground for installation on walls.
[0116] This lift roller fits the Safeway scaffolding with the round frames. The frame is made of 1 steel. There is a steel rod through the middle of the roller, supported by two nylon plastic washers, one at each end (one is and the other is 3/16). The plastic roller is 2 diameter by 3 long made with UHMW plastic.
[0117] A separate DSR with square tubing is also being manufactured for use with the Perry and Baker with square frames. The materials and assembly for the DSR for the Perry and Baker scaffolds will be identical to the materials and assembly as for the Safeway scaffold except that the flange will be square instead of round.
