脱作業に手間がかかるのみならず、バランスウェイト落
下による事故発生の危険があった。
For example, when a work device is attached to or removed from a work vehicle as an attachment, the weight balance of the vehicle body is disrupted when the work device is not attached, so a balance weight is attached to maintain the balance. Attachment and detachment must be carried out by a person or, in the case of heavy items, by mechanical force such as a crane, which not only takes time and effort, but also poses a risk of accidents due to falling balance weights.

本考案は、上記の点に鑑み、バランスウェイトを車体に
、容易かつ安全に着脱できるようにすることを目的とす
る。
In view of the above points, the present invention aims to enable a balance weight to be easily and safely attached to and removed from a vehicle body.

本考案はそこで、次のような技術手段を講じた。The present invention therefore takes the following technical measures.

ウェイト部分を、略作業車への取付レベルにまで対地浮

A support device is provided with legs that support the weight portion on the ground so that it can be independently held while floating above the ground to approximately the level of attachment to a work vehicle, and the vertical relative position of the support device is changed with respect to the weight portion. The leg portion of the support is provided with a push-up mechanism for fixably attaching the weight portion and the support above the attachment level to the work vehicle.

以上の構成による本考案の効果は次の点にある。The advantages of the present invention with the above configuration are as follows.

容易迅速かつ安全に作業を行えるに至った。
In other words, when the balance weight is not in use, it can stand on its own with the support device with the weight section positioned at a level suitable for attaching and detaching from the work vehicle, and furthermore, in the free-standing state, the weight section cannot be pushed up by the push-up mechanism. This makes it possible to extremely minimize the amount of lifting and lowering of the heavy weight part when attaching and detaching it from the work vehicle, and the work can be done easily, quickly and safely without the use of special equipment.

次に、本考案の実施例を図面に基づいて詳述する。Next, embodiments of the present invention will be described in detail based on the drawings.
