Abstract
Improvements in a caster wheel tilt bar is disclosed. The caster wheel tilt bar is installable and removeable on a caster and is secured over one side of the caster frame and utilizes the tapered portion of the wheel frame. When the cart frame is rotated the tilt bar comes in contact with the ground. Further rotation lifts the wheel above the ground. The tilt bar can be configured in an arc or can be configured with defined angular steps. The angular steps are generally calculated to create a balance point where the cart can hold with limited rocking. The caster wheel tilt bar can also be painted or powder coated to match the color of the pre-existing caster wheel. Because the rod and shoe can be different components, the shoe or rod can be adjusted to accommodate different casters and/or wheel diameters.
