Then, the rectangular tube 2, connecting frame 4 and connecting plate 5 are bolted to the frame body 1 in sequence, and finally, it is combined with the accessories on the elevator, thereby realizing the decomposition of the elevator machineless roof bracket and avoiding the integrated setting of the elevator machineless roof bracket, thereby reducing the volume of the machineless roof bracket and providing convenience for the transfer of the machineless roof bracket during installation. There is no need to constantly adjust the position of the machineless roof bracket when entering the elevator shaft, thereby improving the installation efficiency of the elevator by the staff.

[0028] Preferably, Figure 3 As shown, the inner side wall of the elevator longitudinal beam 11 is welded with a reinforcing block 8. Two groups of reinforcing blocks 8 are provided, and the two groups of reinforcing blocks 8 are symmetrically distributed on both sides of the elevator longitudinal beam 11.
