摘要： Recreation and work-type trailers are difficult to maneuver once detached from the towing vehicle even with the conventional dolley wheel in place. This device includes a horizontal main bar with a pair of plates one at each end being mounted to the underside of the main bar by a bolt and spring loaded to give a limited flexibility thereto. A central socket is pivoted to the upper side of the main bar and receives the stem of the trailer hitch. A handle socket is secured adjacent each end of the main bar also on the upper surface thereof and incline upwardly and outwardly therefrom and selectively receive an elongated handle so that the respective end of the main bar can be elevated by the handle and "walked" forwardly or backwardly or sideways as desired thus maneuvering the trailer readily and easily.
摘要翻译：即使使用传统的多功能轮，娱乐和工作型拖车一旦从牵引车辆脱离就难以操纵。该装置包括具有一对板的水平主杆，每个板的一端通过螺栓和弹簧加载到主杆的下侧，以给予其有限的灵活性。中心插座枢转到主杆的上侧，并接收拖车挂钩的杆。手柄插座也在其上表面上固定在主棒的每个端部附近并且从其向上和向外倾斜并且选择性地容纳细长的手柄，使得主杆的相应端部能够被手柄提升并且向前“行进” 或根据需要向后或侧向，从而容易且容易地操纵拖车。
