The invention discloses a transmission device of a single-blade lifting appliance and the single-blade lifting appliance. The transmission device comprises a transmission assembly, a speed reducer, at least one hydraulic motor and a hydraulic valve group; the transmission assembly is arranged on a spindle of the single-blade lifting appliance; the input end of the speed reducer is connected with each hydraulic motor, and the output end of the speed reducer is connected with the transmission assembly; the hydraulic valve group is connected with an output shaft of each hydraulic motor; the output shaft of each hydraulic motor rotates clockwise or anticlockwise by switching the oil inlet direction or the oil return direction of a reversing valve in the hydraulic valve group, and the transmission assembly correspondingly drives the spindle to rotate, so that a lifting appliance main body of the single-blade lifting appliance rotates. The hidden danger of oil leakage of a hydraulic cylinder is eliminated, the failure rate is reduced, and maintenance is more convenient and faster.

    本发明公开了一种单叶片吊具传动装置及单叶片吊具,所述传动装置包括:传动组件、减速机、至少一个液压马达和液压阀组;所述传动组件设置在所述单叶片吊具的主轴上;所述减速机的输入端与每一所述液压马达连接,所述减速机的输出端与所述传动组件连接;所述液压阀组与每一所述液压马达的输出轴连接;通过液压阀组中的换向阀进油或回油的方向切换使所述液压马达的输出轴进行正时针或逆时针旋转,所述传动组件相应驱动所述主轴发生旋转,以使所述单叶片吊具的吊具主体进行回转运动。本发明消除了液压缸漏油的隐患,降低了故障率,使维护更方便快捷。
