Abstract

<P>PROBLEM TO BE SOLVED: To easily move a crane body by increasing strength of a girder while facilitating the vertical movement of the girder by a crane combined with a horizontal girder and a parallel link mechanism. <P>SOLUTION: The horizontal girder is reinforced as a triangular truss, and the parallel link mechanism is composed of two sets, and the truss highest part of the girder is combined as a pin support by sandwiching from both sides by a tip part of the parallel link mechanism. The horizontal girder can be folded up by horizontally revolving in the central vicinity of the girder when moving the crane. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

水平桁の長さを長く出来るようにトラスとして補強した，水平桁の中央付近のトラス最高部を二組の平行リンク機構の先端部で外側から挟みピン支持にて組み合わせた，平行リンク機構を俯仰させるだけで水平桁の上下動を容易にし，且つ水平桁は中間付近で折り畳み可能とした。A parallel link mechanism that is reinforced as a truss so that the length of the horizontal girder can be increased, and the highest part of the truss near the center of the horizontal girder is sandwiched from the outside by the tip of two parallel link mechanisms and supported by pin support. This makes it easy to move the horizontal girder up and down, and the horizontal girder can be folded around the middle.

従来，ブーム式クレーンは吊荷の水平移動の為にはブームを大きく俯仰させねばならない，又水平桁式クレーンは上下動が容易では無いと言う欠点が有った。Conventionally, boom cranes have had the disadvantage that the boom has to be lifted up and down to move the suspended load horizontally, and that horizontal girder cranes are not easy to move up and down.

水平桁の上下移動が非常に簡単になった又桁の長さを長く出来るので荷役スピードが向上する。水平桁の略半分を折り畳めるので全体がコンパクトになりクレーンを移動させ易い。The horizontal girder can be moved up and down very easily, and the length of the girder can be lengthened to improve the handling speed. Folds almost half of the horizontal girder, so the whole is compact and the crane can be moved easily.

吊荷の水平移動距離が長くてクレーンの高さを小刻みに変える必要がある場合に有利である。This is advantageous when the horizontal movement distance of the suspended load is long and it is necessary to change the height of the crane in small increments.

Claims

B) The horizontal girder is a triangular truss.
B) The parallel link mechanism that supports the horizontal girder is composed of two sets, which are combined with the highest part of the truss and the pin support so that the horizontal rod is sandwiched from both sides.
C) The horizontal girder is moved up and down by raising the link mechanism.
A crane configured as described above.

In addition to the first aspect, the portion of the horizontal girder from the highest portion of the truss is turned horizontally and can be folded.
Crane constructed as above
