System and method for aligning portions of a loading ramp |
摘要 |
A system for aligning outer edges of upper surfaces of ramp portions of a loading ramp. The system may include a plurality of sensors configured to provide signals indicative of whether the outer edges of upper surfaces of adjacent ramp portions are aligned. The system may also include a plurality of actuators configured to raise and lower at least one of the outer edges of an upper surface of a ramp portion. The system may also include a controller configured to receive signals from the plurality of sensors, determine whether the outer edges of upper surfaces of adjacent ramp portions are aligned, and provide signals to the actuators to affect movement thereof causing the outer edges of the upper surfaces of the adjacent ramp portions to be aligned. |

1. A system for aligning outer edges of upper surfaces of ramp portions of a loading ramp, the system comprising:
a plurality of sensors configured to provide signals indicative of whether the outer edges of upper surfaces of adjacent ramp portions are aligned; a plurality of actuators configured to raise and lower at least one of the outer edges of an upper surface of a ramp portion; and a controller configured to:
receive signals from the plurality of sensors;determine whether the outer edges of upper surfaces of adjacent ramp portions are aligned; andprovide signals to the actuators to affect movement thereof causing the outer edges of the upper surfaces of the adjacent ramp portions to be aligned. |
