[0046] It is worth adding that the support frame 22 is fixedly welded to the U-shaped frame 20. First trapezoidal blocks 21 are provided at the top of the U-shaped frame 20.

[0049] When it is necessary to adjust the distance between the suspension support assemblies 2 and hoist an object with a small hoisting length, the dual-shaft motor 11 is powered on, and the output shaft rotates forward, driving the left threaded rod 12 to rotate forward and the right threaded rod 12 to rotate reversely, thereby realizing the inward movement of the two U-shaped frames 20. When it is necessary to hoist an object with a large hoisting length, the output shaft of the dual-shaft motor 11 rotates reversely for adjustment and cooperation. When it is necessary to hoist objects at different heights, when hoisting an object with a high hoisting height, the hydraulic cylinder 222 is started, and the telescopic arm extends, driving the bracket 23 to move upward on the support frame 22, and the position of the hook 2322 rises, which helps to hoist objects at multiple heights in cooperation. When it is necessary to hoist an object with a low hoisting height, the telescopic arm of the hydraulic cylinder 222 shortens, and the position of the hook 2322 drops, realizing stable hoisting cooperation;

[0050] With the cooperation of the spring 2323 and the damper 2324, the suspension rod 2321 slides on the support frame 22, reducing the damage impact of vibration on the hoisted object and realizing the seismic function.
