What makes the TruStack Dolly caster configuration so special?

The TruStack Tire Dolly uses 5 casters. Most platform dollys or tool carts use 4. If you have had the opportunity to use a shopping cart at IKEA, you will know right away how difficult it is to control a shopping cart with 4 swiveling casters. Furniture dollys are much the same. That design requires constant attention to the direction of momentum and requires a strong commitment of energy to redirect the cart, and the more weight, the more difficult the job. Regular shopping carts and some tool carts use 2 fixed wheels and 2 swivel casters. This is easier in some ways because the rigid wheels add directional stability, but it then becomes a bigger challenge to steer. On a grocery cart, you may have noticed that the more weight placed over the steering wheels, the more difficult it is to change the direction of travel. Or if the swiveling wheels are nearest you, you must be the person on the end of a whip to take a turn.

The TruStack tire dolly places two of the five wheels in an exactly parallel position, near the rotational center, leaving a front swivel wheel and two rear swivel wheels. The result is surprising. Regardless of the load, light or heavy, the TruStack Tire Dolly moves along easily with excellent directional stability, retaining the ability to stop and spin in place for tight turns or redirection.
