【発明の属する技術分野】
本発明は、トラック等の車両のシャーシフレーム上に架装される車両架装式クレーンに取付け、車両架装式クレーンを投光器として利用するための投光器アタッチメントに関するものである。
【0002】
【従来の技術】
車両架装式クレーンは、トラック等の車両のシャーシフレーム上に架装搭載されるクレーンであって、アウトリガによって支持されるベース上に、旋回するコラムが立設され、このコラムに伸縮ブームが起伏自在に枢着されている。
この車両架装式クレーンは、ブームの先端に投光器アタッチメントを取付けることにより、移動可能な投光器として利用される。
【0003】
従来の投光器アタッチメントは、ブームに連結される連結部材と、連結部材に対してチルト自在なランプ取付部材とを備えており、係合溝とピン挿通孔とを備えた連結用のブラケットをブームの先端に固着し、連結部材の係合ピンをブラケットの係合溝に嵌め込み、ピン挿通孔にロックピンを挿通して連結部材を固定するように構成されていた(特開平11−120813号参照)。
【0004】
【発明が解決しようとする課題】
従来の車両架装式クレーン用の投光器アタッチメントは、ブームへの取付け、取外しを行う場合には、連結部材とブーム先端との位置を合わせるため、他のクレーンで吊上げて着脱するか、又は、車両の荷台上に設けた専用の台座の上に載置して着脱しなければならなかった。
【0005】
また、投光器アタッチメントをブームに取付けた状態で車両を走行させる場合には、振動衝撃が大きくなり、しばしばランプの損傷を生じていた。
本発明は、車両架装式クレーン用の投光器アタッチメントにおける上記問題を解決するものであって、ブームへの取付け、取外しを行う場合に、他のクレーンや専用の台座等の補助手段を用いないで着脱することが可能であり、また、投光器アタッチメントをブームに取付けた状態で車両を走行させた場合の振動衝撃を低減させ、ランプの損傷を防止することのできる車両架装式クレーン用の投光器アタッチメントを提供することを目的とする。
【0006】
【課題を解決するための手段】
この発明では、上記課題を解決するため、車両架装式クレーンのブームに連結される連結部材と、連結部材に対してチルト自在なランプ取付部材とを備えた車両架装式クレーン用の投光器アタッチメントにおいて、前記ランプ取付部材には、伸縮可能な4つの支柱設けられ、該4つの支柱のうち、前記ブーム側となる基端側の左右の支柱は、前記ランプ取付部材に垂直に取付けられ、前記ランプ取付部材の先端側の左右の支柱は、互いにクロスするように取付けられており、各支柱は、外筒と、該外筒内に摺動自在に嵌挿された内筒とからなり、各内筒が各外筒から下方へ引出された伸長位置と、各内筒が各外筒内に格納された縮小位置とに、固定ピンで固定されるようになっている
【0007】
投光器アタッチメントをブームに取付ける場合には、まず、投光器アタッチメントの取付対象である車両架装式クレーン自体を用いて投光器アタッチメントを吊上げ、支柱を伸長させて連結部材が所定の高さとなるように車両の荷台上に載置する。
次に、ブームを起伏、伸長させ先端を連結部材に位置合わせして連結した後、支柱を短縮する。この状態で、ブームを起立させランプ取付部材をチルトさせることにより、車両架装式クレーンが投光器として使用可能となる。
【0008】
投光器アタッチメントをブームに取付けたまま車両を走行させる場合には、ブームを倒伏させ、支柱を下端が荷台に当接するまで伸長させることにより支柱で投光器アタッチメントとブームの先端側を支持する。この状態で車両を走行させれば、振動衝撃が低減し、ランプの損傷を防止することができる。
投光器アタッチメントを取外す場合には、取付けと逆の手順で行えばよい。取外された投光器アタッチメントは、支柱を保管用の架台として所定の保管場所に保管しておく。
【0009】
投光器アタッチメントを取外した車両架装式クレーンは、通常のクレーン作業に使用できる。
