CLAMP DEVICE OF TRAVELING CRANE

To provide a clamp device for a traveling crane capable of reducing weight and simplifying whole structure.SOLUTION: A long member 10 is provided in an approximately horizontal state along a rail R, a shoe surface which can be brought into pressure contact with a rail head side surface 8 is formed on a tip of the long member 10, and the tip of the long member 10 is connected to a lower end part 5A of a clamp arm 5. In addition, a braking shoe surface, which is freely brought into pressure contact with or separated from the rail head side surface 8 by the swinging of the clamp arm 5, is formed on the tip of the long member 10. Most of crane runaway preventing force is snatched by the long member 10 in the approximately horizontal state without through a clamp main body 1 and a clamp main body mounting frame 52 under a clamp state in which the shoe surface of the long member 10 is brought into pressure contact with the rail head side surface 8 so as to be transmitted to the frame structure through the long member 10.SELECTED DRAWING: Figure 3 【課題】全体の構造を、軽量化でき、かつ、簡素化できる走行クレーン用クランプ装置を提供する。【解決手段】レールＲに沿って略水平状に長尺部材１０を設け、この長尺部材１０の先端に、レール頭部側面８に対して圧接可能なシュー面を形成し、この長尺部材１０の先端を、クランプアーム５の下端部５Ａと、連結する。しかも、上記長尺部材１０の先端には、上記クランプアーム５の揺動により上記レール頭部側面８に対して圧接分離自在な制動用シュー面が、形成され、上記長尺部材１０のシュー面が上記レール頭部側面８に圧接したクランプ状態下で、クレーン逸走阻止力の大半が、上記クランプ本体１及びクランプ本体取付枠５２を介さずに、上記略水平状の長尺部材１０にて横取りされて、該長尺部材１０を介して、上記フレーム構造体へ伝達されるように構成した。【選択図】図３
