【発明の詳細な説明】
この発明は、土木工事に用いる油圧ショベルで重量物を
吊揚げるための方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for lifting heavy objects with a hydraulic excavator used in civil engineering work.
各種土木工事は、土砂の掘削だけでなく、重量物を吊上
げ移動させる作業が多々発生する。Various types of civil engineering work often involve not only excavating earth and sand, but also lifting and moving heavy objects.
土木工事には、ブームの先端側にパケットを取付けた油
圧ショベルが掘削作業用として広く一般に使用されてい
る。In civil engineering work, hydraulic excavators with a packet attached to the tip of the boom are widely used for excavation work.
このような油圧ショベルは、ブーム先端のパケットを取
外して吊具を取付け、この吊具で吊揚げを行なうことも
可能ではあるが、吊揚げ重量は重体取量との釣合う範囲
に制限を受けるため、＃置物の吊揚げは不可能であり、
また、軽量物の吊揚げでも短芯が前方に移動するため、
傾斜地等では転倒するという危険がある。With such hydraulic excavators, it is possible to remove the packet from the tip of the boom and attach a lifting device to perform lifting, but the lifting weight is limited to a range that is balanced with the amount of heavy objects that can be lifted. Therefore, it is impossible to lift the figurine.
In addition, when lifting lightweight objects, the short core moves forward, so
There is a risk of falling on slopes, etc.
また、重量物の吊揚げを行なうには、大型クレーン車の
使用が考えられるが、山間部やスペースの狭い部分への
大型クレーン車の進入は不可能であり、このような部分
での重量物の吊揚けは実際上困難である。In addition, to lift heavy objects, it is possible to use a large crane truck, but it is impossible for large crane trucks to enter mountainous areas or areas with narrow spaces. Lifting is difficult in practice.
さらに、重量物吊場げのために、専用のクレーンを使用
するということは、多額の設備費用が必要になり、作業
コストが高くつくという経済的な問題も発生する。Furthermore, using a dedicated crane for lifting heavy objects requires a large amount of equipment costs, which also causes economic problems such as high work costs.
この発明は、上記のような点にかんがみてなされたもの
であり、油圧ショベルの品物吊場げ状態が安定し、小型
の油圧ショベルで重量物の吊揚げを行なうことができる
吊揚げ方法を提供するのが目的である。This invention has been made in view of the above-mentioned points, and provides a lifting method that stabilizes the state of lifting goods on a hydraulic excavator and allows heavy objects to be lifted with a small hydraulic excavator. The purpose is to.
以下、この発明を添付図面の実旌例に基づいて説明する
。Hereinafter, the present invention will be explained based on practical examples shown in the accompanying drawings.

端に枢止したアーム５をシリンダ６で起伏動自在とし、
アーム５の先端にパケット７等のアタッチメントとこれ
を作動させるシリンダ８を取付けて構成されている。As shown in the figure, the hydraulic excavator has a car body 2 mounted on a crawler 1 so as to be able to rotate freely, and a boom 3 attached to the front of the car body 2.
is mounted so that it can be raised and lowered by a cylinder 4, and an arm 5 that is pivotally fixed to the tip of the pool 3 can be raised and lowered by a cylinder 6,
It is constructed by attaching an attachment such as a packet 7 to the tip of an arm 5 and a cylinder 8 for operating the attachment.
上記油圧ショベルは、ブーム３１．アーム５及びパケッ
ト７の揺動と、車体２の旋回、移動等を操作することに
より、土砂の掘削作業を行なうものである。The hydraulic excavator has a boom 31. Earth and sand excavation work is performed by operating the swinging of the arm 5 and the packet 7 and the turning and movement of the vehicle body 2.
前記ブーム３の途中に滑車９を枢設し、この滑車９から
垂下させたワイヤ１０の先端にフック等の吊具１１を取
付け、ワイヤ１０の基端側は車体２に設けたウィンチ１
２に巻装されている。A pulley 9 is pivotally installed in the middle of the boom 3, a hanging device 11 such as a hook is attached to the tip of a wire 10 hanging from the pulley 9, and the base end of the wire 10 is connected to a winch 1 provided on the vehicle body 2.
It is wrapped in 2.

送可能となる。In this state, connect the hanging tool 11 to the heavy object A, and
If the wire 10 is wound up by operating the
will be lifted up, and by inserting a cart or the like under the lifted heavy object A, and placing the heavy object A on this cart, the object can be transported.
なお、吊具１１はミ図示のようなワイヤ一式に限定され
るものではなく、例えば油圧シリンダやチェンブロック
等を使用してもよい。Incidentally, the hanging tool 11 is not limited to a set of wires as shown in the figure, and for example, a hydraulic cylinder, a chain block, or the like may be used.
以りのように、この発明によると、油圧ショベルの車体

の吊揚げを実施することができる。As described above, according to the present invention, a gate-shaped frame is formed on the ground by the body of the hydraulic excavator, the boom, and the arm, and a lifting device is attached to the middle of the boom in this frame to perform lifting. Weight support can be carried out at both ends of the pool, and there is no need to use the suspension weight of a vehicle body, etc., and heavy objects can be lifted using a small hydraulic excavator.
また、小型油圧ショベルでの重量物の吊揚げが安定よく
行なえるので、山間部やスペース的に狭い場所でも重量
物の吊揚げが可能になり、専用クレーンの使用が省ける
ので、設備経費の削減を図ることができる。In addition, since the lifting of heavy objects can be performed stably using a small hydraulic excavator, it is possible to lift heavy objects even in mountainous areas or places with limited space, and the use of a special crane can be omitted, reducing equipment costs. can be achieved.
