本考案は、起重機用落下防止装置に関するもの
で、移動するトロリーを有するけたを持つ起重機
等に適するものである。[Detailed Description of the Invention] The present invention relates to a fall prevention device for a hoist, and is suitable for a hoist having a girder having a movable trolley.

に制限が出てくるという問題があつた。 Conventionally, for safety during inspection and maintenance, a net was hung from a guide rope and expanded and contracted along with the trolley. In this conventional method, the hanging equipment of the net suspended from the guide rope slides as the trolley moves, resulting in frequent damage to the hanging equipment and wire rope.Also, the storage space for the net is large, and the distance the trolley must travel
There was a problem that there were restrictions on

にしたものである。 In order to eliminate the above-mentioned problems, the present invention provides drums for winding the net at both ends of the girder, and rotates the drums as the trolley moves.

１にテンシヨンを与えて取付ける。 An embodiment of the present invention is shown in FIGS. 1 and 2. In the figure, net winding drums 2 and 3 are rotatably installed at both ends of the girder 5 on which the trolley 1 runs, with one end fixed to the trolley 1 and the other end attached to the winding drums 2 and 3. Fixed nets 4 and 7 are installed before and after the trolley 1.
Separately from the nets 4 and 7, a drum driving rope 6 is fixed at one end to the trolley 1 as shown in FIG. .
この状態で、トロリー１がけた５上を矢印方向

きる。逆の方向に移動する場合も同様である。 In this state, when the trolley 1 moves on the girder 5 in the direction of the arrow, the winding drums 2 and 3 are rotated clockwise by the driving rope 6 to wind up the net 4 and unwind the net 7 on the other side. can. The same applies when moving in the opposite direction.

ある。 According to the present invention, conventional guide ropes and hanging devices are no longer necessary and damage is avoided, and by installing the winding drum on the side or bottom of the girder, it can be stored in a small space and does not interfere with the range of movement of the trolley. It has the effect of not giving.
