When power failure, pulley (9) is contained on the square axle (41), locks with locking nut (42). Handle (23) and suspension chain (22) are arranged on pulley (9), as shown in Figure 3,4.

Its guiding mechanism (40) is as shown in Figure 1: is made up of guide rail (5) adjustment connecting rod (2) and guide body (3).

The guide rail (5) is installed on one side of the gable wall and is parallel to the gable wall, and its shape is equidistant to the projection line of the gable top. 6) On, the material can be garden pipe, channel steel, I-shaped outline, etc., as shown in Figure 6.

One end of the adjusting connecting rod (2) is hingedly connected to the reducer (1) and the other end is connected to the guide body (3), as shown in Figure 5, the upper end of the adjusting connecting rod (2) is mounted on the pin shaft (22), and the pin shaft (22) Fixed on the bottom plate (24), the bottom plate (24) is fixed on the bottom surface of the reducer (1), the pin hole (43) on the upper end of the connecting rod (2) is adjusted to move with the pin shaft (22), and the retaining ring (23) and The lock nut (25) is fixed.
