The Quality Stainless Products (QSP) Tire and Wheel Lift, No. LM-350, is designed for the heavy duty service industry. Tire and wheel assemblies can weigh as much as 350 lbs, making them difficult for one person to mount and demount. The LM-350 offers an off-center column design that helps improve access to lug nuts, wheel balancers and tire changers. This unit offers variable speed control for raising and lowering wheel assemblies safely. The dual rollers are designed to allow independent rear dual wheel rotation.
