  • APPARATUS AND METHOD FOR LOWERING AND RAISING A TRAILER
    Publication number: 20230242083
    Abstract: A landing gear assembly includes a leg assembly, a gear assembly configured to telescopingly move a second leg portion with respect to a first leg portion, and a drive assembly including a gear arrangement configured to drive the drive shaft of the gear assembly at a high speed and low torque configuration and at a low speed and high torque configuration, an electric motor configured to drive the gear arrangement, and a controller configured to switch the gear arrangement from the high speed and low torque configuration to the low speed and high torque configuration in response to an increase in current draw by the electric motor as the second leg portion moves from a retracted to an extended position, and configured to maintain the gear arrangement in the high speed and low torque configuration as the second portion moves from the extended position toward the retracted position.
