あつた。 Hanging tool A suspended from the tip of boom B
However, in order to prevent problems such as collision with or abnormally approaching boom B due to abnormal over-winding of rope 1, and the fall of the load hung on this hoist A, there is a , overwinding detection switch 2
has been set up. This switch 2 is the same switch 2
Due to the weight of the weight 3, which can be raised and lowered freely along the rope 1, which is suspended from When lifted upward by fixture BA, things that were previously ON are switched OFF and things that were OFF are switched ON, which can cause an alarm to be issued or a safety valve in the hydraulic circuit to be activated. The hoisting tool A was automatically stopped by acting on the hoisting tool A.
ところでこのウエイト３は、上記の際に吊具Ａ
の滑車４にかみ込むことがあり、この場合には、
滑車４を損傷したりする不具合があつた。 By the way, this weight 3 is used as the hanging tool A in the above case.
may get caught in the pulley 4 of the
There was a problem that caused damage to pulley 4.
本考案は、簡単な構成でありながら前記不具合
を防止できるようにした新規なクレーン用吊具を
提供することを目的としている。 An object of the present invention is to provide a novel crane hoist that has a simple structure and can prevent the above-mentioned problems.
次に本考案第２図、第３図に示した１実施をも
とに詳細に説明する。 Next, a detailed explanation will be given based on one implementation of the present invention shown in FIGS. 2 and 3.

てもよいこと勿論である。 5 is a side plate; 6 is a rope end stopper shaft 6 disposed above the side plate 5 in parallel with the support shaft 4' of the pulley A; 7 is a rope end stopper shaft 6; A rope end stopper connected to the Reference numeral 8 designates a spacer serving as a weight receiver, which is disposed below the rope end stopper shaft 6, above the pulley 4, and protrudes so as to intersect with the support shaft 6 in plan view. Fixed. This spacer 8, which also serves as a weight receiver, reduces the distance between the side plates 5, 5, which is widened due to the pulley 4 disposed between the side plates 5, 5, so that the rope end stopper 7 can be attached to either side of the side plates 5, 5. This prevents it from being biased to one side. In addition, this spacer 8 that also serves as a weight receiver
In the above figure, a pair of the holes are arranged on the left and right sides, but it goes without saying that a single piece formed in a U-shape may also be used. In this way, since the rope end stopper metal fitting 7 is prevented from being biased to one side, the rope end stopper metal fitting 7 is hung on the rope end stopper support shaft 6, and the hanging tool A is suspended by one rope. Hanging tool A does not tilt when . In the above embodiment, the weight receiving spacer 8 is provided below the rope end stopper shaft 6, but it is of course possible to provide it above.
このようにウエイト受け兼用スペーサ８を設け
たときには、ウエイト３がロープの巻過ぎ時に滑
車４にかみ込むことがないという実用上秀でた効
果を奏する。 When the weight receiving spacer 8 is provided in this manner, an excellent practical effect is achieved in that the weight 3 does not get caught in the pulley 4 when the rope is overwound.
