Abstract: The drywall scaffold roller (“DSR”) is a lightweight tool weighing approximately two pounds that construction workers who hang drywall (or plywood) can use to roll the heavy material from the ground to the workers on a scaffold instead of lifting it themselves using their back, arms and legs, which causes injuries. Currently, a drywaller on the ground physically lifts a 100+ pound sheet of drywall, plywood or other heavy materials upwards as much as 20 feet to the person on the scaffold, who then has to lift and/or pull the materials up onto the scaffold. Both people must use their arms, knees, shoulders and back to lift the heavy material, and the worker on the scaffold sometimes uses his foot to slide the material up onto the scaffold. The DSR helps eliminate this unsafe lifting procedure by providing a rolling mechanism to roll the sheet of material instead of lifting it.
