PILE DRIVER
To provide a pile driver equipped with a work platform elevating device capable of elevating and lowering a work platform with a compact configuration.SOLUTION: In a steadying device 23 provided on a pile driver, a pair of steadying members 28 are provided on a base member 29 so as to be openable and closable, and is provided so that it can be raised and lowered below the height position of a work device via a steady rest device lifting mechanism that includes a pinion gear that meshes with a rack gear 24 provided on a front surface of a leader 15, and a steady rest lifting motor that drives the pinion gear. The pair of steadying members 28 are formed so as to be rotatable around a pair of pivot pins 41 in the width direction of an upper revolving body provided on the base member 29 between a closed state where the rotating ends are close to each other and an open state where the rotating ends are separated from each other. The base member 29 is provided with a workbench mounting portion 30 to which a workbench 27 is attached and the steadying member 28 in the open state is positioned in an underfloor space S thereof.SELECTED DRAWING: Figure 3
【課題】コンパクトな構成で作業台昇降を行うことが可能な作業台昇降装置を備えた杭打機を提供する。【解決手段】杭打機に備わる振止装置２３は、ベース部材２９に一対の振止部材２８が開閉可能に設けられるとともに、リーダ１５の前面に設けられたラックギヤ２４に噛合するピニオンギヤと、該ピニオンギヤを駆動する振止装置昇降モータとを有する振止装置昇降機構を介して作業装置の高さ位置よりも下方で昇降可能に設けられ、一対の振止部材２８は、ベース部材２９に設けられた上部旋回体幅方向一対の回動ピン４１を中心として、回動端同士が接近した閉じ状態と、離反した開き状態とに回動可能に形成され、ベース部材２９には、作業台２７を取り付けてその床下空間Ｓに開き状態の振止部材２８を位置させる作業台取付部３０が設けられている。【選択図】図３
