To provide a safety system for a pile driver that can ensure the safety of a worker engaged in pile driving work by quickly stopping the rotary drive of an auger in an emergency.SOLUTION: In a safety system of a pile driver equipped with a safety circuit that stops ascending/descending operation of an auger in response to an operation signal of an emergency stop switch 36, a portable engine generator 23 is mounted on a rear frame 24 of an upper revolving body 13 as a power source for rotationally driving the auger. The safety circuit comprises a communicator capable of wireless communication with the portable engine generator. In response to reception of the operation signal of the emergency stop switch, a stop signal for stopping the power supply from the portable engine generator is generated. Further, the emergency stop switches are provided at a plurality of locations on the upper revolving body, and include an operator switch that can be operated from an operator's cab and a worker switch that can be operated from the ground.SELECTED DRAWING: Figure 3
【課題】緊急時にオーガの回転駆動を素早く停止することにより、杭打ち作業に従事する者の安全確保が可能な杭打機の安全システムを提供する。【解決手段】非常停止スイッチ３６の操作信号を受けて、オーガの昇降動作を停止させる安全回路を備えた杭打機の安全システムにおいて、上部旋回体１３の後部架台２４上に、オーガを回転駆動させる動力源として可搬式エンジン発電機２３が搭載され、前記安全回路は、可搬式エンジン発電機との間で無線通信が可能な通信機を備えるとともに、非常停止スイッチの操作信号を受けて、可搬式エンジン発電機からの電力供給を停止させる停止信号を生成する。また、非常停止スイッチは、上部旋回体の複数箇所に設けられ、運転室内から操作可能な運転者用スイッチと、地上から操作可能な作業者用スイッチとが含まれる。【選択図】図３
