Shoulder dolly makes moving large/bulky objects much easier. It significantly reduces strain and risk of injury to the low back, keeps object off of the ground and eliminates floor damage---save your back, reduce damage to floors, doorjams, and walls.
Shoulder Dolly Light Duty gives you a hand in moving the heavy stuff--and reduces back, arm, and hand strain. You're looking at a 2-person harness, webbing and buckle system designed by a professional mover to ease the burden of lifting heavy and bulky objects. Shoulder Dolly lets 2 movers lift in an upright position instead of bending over, so they use shoulder and leg muscles instead of their backs, hands, biceps, and forearms. Both movers slip into their harnesses, adjust webbing for differences in their heights and the weight of the object, place webbing under the object, and lift. Movin' on up: Recommended weight capacity up to 400 pounds. Encourages safe lifting techniques and reduces injury risk. Eliminates damage caused by hand trucks and traditional dollies--no more marring walls, floors, doors, and furniture. Increases efficiency. Superior to systems that utilize stronger muscles to bear weight. Excellent for going up and down staircases. Weighs 4 pounds.
