PILE DRIVER AND METHOD FOR USING PILE DRIVER
To provide a pile driver and a method for using the same comprising handrail devices for which high place work caused by operation for lying handrails down and returning handrails to the original raised state is not required, and that can be safely and easily handled.SOLUTION: A parallel link that can move in the front-rear and vertical directions is formed on an upper section of a handrail device 23 while a handrail body 28 remains in a horizontal state. On the upper end of a lower support 24, an arc and long guide hole 32b that extends in the circumferential direction of a lower support pin 25 is provided. A guide pin 33 provided at a lower section of an upper support 26 is formed so as to be able to engage with the guide hole and to pivot on the lower support pin. Because of this, a swinging angle range A for the upper support is set. The parallel link can move to: a laid down position in which the handrail body is lower than the limit height defined by regulations when a pair of upper supports reach the lower limit angle in the swinging angle range; and a raised position in which the handrail body is higher than the limit height when the pair of upper supports reach the upper limit angle in the swinging angle range.SELECTED DRAWING: Figure 3
【課題】手摺りを倒したり、起こして元の状態に戻したりする動作に伴う高所作業をなくして、安全かつ容易に取り扱うことが可能な手摺装置を備えた杭打機及び杭打機の使用方法を提供する。【解決手段】手摺装置２３の上部に手摺本体２８が水平を保ったままで前後方向及び上下方向に移動可能な平行リンクが構成され、下部支柱部２４の上端部には、下支持ピン２５の周方向に延びる円弧長孔状のガイド孔３２ｂが設けられ、上部支柱部２６の下部に設けたガイドピン３３がガイド孔に係合して下支持ピンの軸まわりに円弧移動可能に形成されることにより、上部支柱部の揺動角度範囲Ａが設定され、一対の上部支柱部が揺動角度範囲のうちの下限角度にそれぞれ到達することで手摺本体が法令上の限界高さよりも低くなる倒伏位置と、一対の上部支柱部が揺動角度範囲のうちの上限角度にそれぞれ到達することで手摺本体が限界高さよりも高くなる起立位置とに移動可能である。【選択図】図３
