Provides a technician with a simple and efficient method of moving a disabled vehicle around a shop environment. Position a dolly at each wheel of a vehicle weighing up to 5,200 lbs. and use the foot pedal to engage the bi-directional ratchet. Mechanical leverage applied to the foot pedal progressively squeezes the vehicle tire between the two rollers until the tire lifts off the ground. Fits tires as wide as 11 inches and up to 34 inches tall. The four heavy-duty, double-ball 3-inch casters can support up to 1,300 lbs. per unit, while at the same time, protecting the shop floor from damage. Sold individually.
