    • The power drive includes a housing enclosing a gearing system and a motor. The housing is mounted under the floor of a transport trailer. A drive shaft extends outside the housing for connection in series with a cross shaft of the landing gear of the trailer. A gear shift actuator is mounted in the gearing system for engagement or idling of the gearing system. The gear shift actuator comprises a rod that is movable in and out of the driver side of the housing. A handle lock saddle is mounted to the driver side of the housing for retaining a crank handle of the landing gear thereto. The saddle is centered on the rod such that the rod must be pushed inward for mounting the crank handle to the handle lock saddle. The gearing system is inoperable if the crank handle is not securely stowed to the handle lock saddle.
    • 动力传动装置包括一个封闭传动系统和电动机的壳体。 外壳安装在运输拖车的地板下面。 驱动轴延伸到壳体外部,以与拖车的起落架的横轴串联连接。 换档致动器安装在齿轮传动系统中用于齿轮传动系统的啮合或空转。 换档致动器包括可移动进出壳体的驾驶员侧的杆。 手柄锁鞍安装在壳体的驱动器侧,用于将起落架的曲柄手柄保持在其上。 鞍座在杆上居中,使得杆必须向内推,以将曲柄手柄安装到手柄锁鞍座上。 如果曲柄手柄未牢固地收放在手柄锁定鞍座上,传动系统是不能操作的。
