る。FIGS. 1 to 3 show an apparatus for preventing a load from being shaken by a suspended load according to the present invention, wherein 1 is a ceiling, 2 is a crane or hoist body running on the ceiling 1, and 3 is a winding drum 4 in the hoist body 2. , A wire rope hanging downward from the lowering port 6 through the sheave 5, and a pair of mounting brackets 7, 7 arranged on the lower surface of the hoist body 2 in a direction orthogonal to the moving direction with the lowering port 6 interposed therebetween; Is a through hole 1 for inserting and guiding the wire rope 3 whose upper end is pivotally supported by the mounting brackets 7, 7 via pivot pins 9, 9 so as to be tiltable.
A cylindrical guide frame 11 having a zero, a mounting bracket 12 fixed to the lower surface of the hoist main body 2 at predetermined intervals before and after in the moving direction of the hoist main body 2 with the descent port 6 interposed therebetween; , 12 have their lower ends pivotally supported by the lower ends of the guide frame 8 via pivot pins 14, 14 and their upper ends can be freely tilted by the mounting brackets 11, 11 via the pivot pins 15, 15. Consisting of a piston pivotally mounted on a cylinder and a cylinder containing a viscous fluid
The dampers 16 are suspended loads suspended via hooks 13 attached to the lower end of the wire rope 3.

るようになる。Since the apparatus for preventing vibration of a suspended load according to the present invention has the above-described structure, when the hoist main body 2 which is moving horizontally on the ceiling 1 is stopped as shown in FIGS. The load 16 swings in the direction of movement through the wire rope 3 due to the inertial force, and then swings in the direction opposite to the direction of movement as shown in FIGS. 5 and 6, and then oscillates like a pendulum. One of the dampers 12 provided before and after the moving direction of the guide frames 8, 8 through which the wire rope 3 is inserted is compressed, and the other is expanded, so that the vibration energy of the suspended load 16 is reduced in the viscous fluid. It is converted into heat energy, and the swing of the suspended load 16 is reduced.
