ABSTRACT:
A trailer landing gear drive system in which pneumatic, hydraulic and electric motors, as well as the traditional hand crank, are easily interchangeable. The landing gear jack mechanism is disposed to easily connect to any one of these drive motors. The system can utilize any one of the three motor combinations without making any change to the jack itself. Each drive motor output shaft is keyed to connect to the input shaft driving the worm gear of the jack. The output shaft of each type of motor is keyed the same so that the motors are swappable with respect to the input shaft of the landing gear. The hand crank shaft is also keyed to be the same as the keyed motor output shafts. Each motor may include a flange to permit it to be secured to the landing gear. The system eliminates the gear reduction box and replaced it with a worm gear. Furthermore, the system can be operated remotely so that the operator need not be exposed to the perils of weather, a shifting load, other vehicles in the vicinity or other similar hazards.
