Both V-belt and Panther drive systems feature different sizes of interchangeable drive (motor) pulleys (or sprockets), which allow the top speed and torque of the chair (or gurney) to be matched to the needs of the user. Two sizes of drive wheel pulleys are also usually available for conventional frames. The factory will optimize drive train ratio based upon user profile information gathered when the chair or gurney is ordered. The dealer can easily make changes in the field should the user's needs change. |
