Abstract
Systems, apparatuses, and methods are described for a vertical platform lift assembly control system are disclosed. The control system may provide a method for monitoring sensors for the vertical platform lift, and may determine operating modes and fault conditions from the sensor data. An indicator system for the vertical platform lift may provide user feedback based on sensor data and the status of the control system.
Claims20
A lift assembly comprising:
- a frame;
- a lift mechanism associated with the frame;
- a platform attached to the lift mechanism;
- one or more sidewalls attached to, and configured to contain, the platform;
- a drive assembly configured to move the lift mechanism, wherein the lift mechanism moves the platform;

- and
- one or more sensors;
- wherein the one or more sensors comprises:
- a temperature sensor associated with the drive assembly;
- a current sensor associated with the drive assembly;
- and
- one or more load sensors, associated with the platform and configured to sense weight of the platform;
- wherein the control system comprises:
- a cab controller comprising one or more user inputs;
- a landing controller comprising one or more user inputs;
- control circuitry;
- one or more connection ports connected to the control circuitry;
- one or more processors connected to the control circuitry;
