1.11 Basket Lift Service Procedures (cont.)
Ultimate Electric Series fryers, used to cook large
amounts of bone-in chicken in a single drop, are
equipped with bell-crank style basket lifts.
Two components, a cam and bell crank, are
connected to the basket lift arm by a flat metal
link. The cam is attached to a drive motor. The
motor rotates the cam, thus raising or lowering
the lift arm linked to the bell crank. A roller-
activated microswitch is used to limit travel.
When the roller in the microswitch is in contact
with the cam, the motor is energized. As the cam
rotates, the roller loses contact with the cam and
the motor power circuit is broken, de-energizing
the motor.
Timing circuitry in the controller initiates and stops basket lift operation. When the product button is
pressed, the timing circuitry activates a coil in the basket lift relay to supply power to the motor. The
microswitch stops the motor at the lift's lower travel limit and the switch contacts are reversed. At
the end of the programmed cooking time, the timing circuit activates the coil once more and the lift
rises until the microswitch again loses contact with the cam, opening the motor power circuit and
stopping the motor. A typical bell-crank wiring diagram is shown below.
