  • Demountable drive mechanism
    Patent number: 7163207
    Abstract: A demountable drive mechanism for coupling to a drive shaft of an operating device, the drive mechanism being directly secured to the drive shaft to cause the drive shaft to rotate, the drive mechanism comprising a geared electric motor having an output for coupling to the drive shaft, the drive mechanism having a torque arm adapted to engage a reaction surface so that the electric motor can impart torque to the drive shaft, and a controller to control operation of the electric motor.
    Type: Grant

  • Powered trailer jacking system
    Patent number: 6598886
    Abstract: A demountable drive mechanism for the landing gear of a semi-trailer, the landing gear including legs that are extendable and retractable by rotation of a drive shaft through a gear mechanism, the drive shaft being axially displaceable to change the ratio of the gear mechanism, the drive mechanism comprising an electric motor having an output shaft adapted to be coupled to the drive shaft of the landing gear assembly, the electric motor being coupled to the landing gear through a torque arm so that the electric motor can impart torque to the drive shaft, means to axially displace the drive shaft to change the gear ratio, and means to control operation of the electric motor and axial displacement of the drive shaft.
