Fig. 1 shows a schematic view of a simple remote-controlled manual lifting device example 1, which will use the simplest solution of manual sliding of a wire-guide lifting mechanism for translation.

As shown in fig. 1, the lifting bracket 02 is installed on a ceiling 01 at the top of a corridor, in this example, the lifting bracket 02 is fixed on the bottom surface of the ceiling 01 by using channel steel crossing and embedding into the walls at both sides of the corridor, and the guide rail steel wire ropes a90 are respectively fixed on the lifting bracket 02 on the ceiling 01 and between the floor 04 by a fixing and tensioning device and are located at the center of the corridor stair 03. The two-storey stairways are illustrated in the figure, and the actual use scene is more multi-storey stairways.

As shown in fig. 3, the elevating bracket a1 and the sliding bracket a2 of the elevating part are schematically illustrated, the elevating bracket a1 has an upper frame a11, a lower frame a12, and left and right frames a13 on both sides, the left and right frames a13 have bushings, bearings or rollers therein, so that the left and right 2 guide wire ropes a90 can be limited in the left and right frames a13 to slide up and down, the left and right 2 elevating wire ropes a91 are fixed to the left and right ends of the upper frame a11 by fixing structures, and of course, the elevating wire rope a91 may be suspended at other positions of the elevating bracket a 1.

The sliding support a2 is in a square frame structure, the upper side frame a21 and the lower side frame a22 are provided with pulley structures at the upper and lower sides, so that the sliding support a2 is limited to slide left and right in the upper and lower side frames of the lifting support a 1. The sliding support a2 is similar to the frame structure of a sliding glass window in the lifting support a 1.
