To provide a truck frame which improves rigidity with respect to an operation load though the structure is simple and is suitable for usage of a pile driver, and the pile driver provided with the truck frame.SOLUTION: A truck frame of a pile driver incudes a cylindrical body 32 of which the center frame comes to an attachment seat of a revolving bearing 13 and back-and-forth and right-and-left leg part side plates 34 which are interposed between upper and lower plates 33, 38 and are extended so that an intermediate part constitutes a part of the cylindrical body. Therein, positions of upper and lower center combining parts 47, 48 which combine the cylindrical body, and the upper and lower central plate parts 33a, 38a are constituted such that the upper center combining part 47 is located on the upper side than a position of the upper end of a side frame 26 and the lower center combining part 48 is located on the lower side than a position of an axis (an axle) 46 of an idler wheel 24, respectively. Further, the lower plate 33 is constituted such that lower central plate part 33a, front leg part lower plate 33c and rear leg part lower plate are composed of a single plate material, and the whole region of the plate surface is flat.SELECTED DRAWING: Figure 14
【課題】シンプルな構造でありながら作業負荷に対して剛性を高め、杭打機の用途に適したトラックフレーム及びこれを備えた杭打機を提供する。【解決手段】杭打機のトラックフレームは、センタフレームが旋回ベアリング13の取付座となる円筒体32と、上下板33,38間に介在されるとともに中間部が円筒体の一部を構成して延びる前後左右の脚部側板34とを備え、円筒体と上下の中央板部33a,38aとを接合する上下のセンタ接合部47,48の位置が、上センタ接合部47はサイドフレーム26の上端の位置よりも上方に、下センタ接合部48は遊動輪24の軸(車軸)46の位置よりも下方にそれぞれ位置している。また、下板33は、下中央板部33a,前脚部下板33c及び後脚部下板が単一の板材からなり、板面の全域が平坦をなしている。【選択図】図14
