Abstract
A controller for a scissor lift control system includes a multiplexing device for lessening the number of conductor lines sent to the controller. The controller includes a microprocessor, and it determines appropriate safe operations of the scissor lift based on various sensed inputs, such as height of the platform and load on the platform. The scissor lift is operated by pushing either a drive select push button, a lift select push button, or a deck select push button. After the switch is selected, the operator has a predetermined amount of time to stroke the joystick in order to effect movement of the scissor lift.
