To provide a pile driver having an inclination detection part which can improve the detection accuracy of the verticality of a pile without lowering the efficiency of piling work.SOLUTION: An inclination detection part 44 for detecting an inclination of a steel pipe pile 35 is arranged at a vibration stopper member 26 for bracing the steel pipe pile 35 which is rotationally driven by a working device. The inclination detection part 44 has a base member 46 to which an inclination sensor 45 for detecting an inclination to a vertical direction as an absolute angle is attached, and a plurality of distance sensors 47 for detecting a distance between the base member 46 and the steel pipe pile 35. The plurality of distance sensors 47 are arranged at the base member 46 apart from each other with a preset interval in a vertical direction and a longitudinal direction. A control part calculates a relative angle between the base member 46 and the steel pipe pile 35 on the basis of an output value of the upper-side distance sensor and an output value of the lower-side distance sensor, and calculates an inclination of the steel pipe pile 35 on the basis of an absolute angle and a relative angle which are detected by the inclination sensor 45.SELECTED DRAWING: Figure 6
【課題】杭打作業の効率を低下させずに、杭の鉛直度の検出精度を向上させることができる傾斜検出部を備えた杭打機を提供する。【解決手段】作業装置によって回転駆動される鋼管杭３５を抱持する振止部材２６に、鋼管杭３５の傾きを検出する傾斜検出部４４が設けられ、該傾斜検出部４４は、鉛直方向に対する傾きを絶対角度として検出する傾斜センサ４５が取り付けられたベース部材４６と、該ベース部材４６と鋼管杭３５との距離を検出する複数の距離センサ４７とを有して構成され、複数の距離センサ４７は、ベース部材４６に互いに上下方向及び左右方向にあらかじめ設定した間隔で離れて配置され、制御部は、上部側の距離センサの出力値と、下部側の距離センサの出力値とに基づいてベース部材４６と鋼管杭３５との相対角度を算出するとともに、傾斜センサ４５の検出により得られた絶対角度と相対角度とに基づいて鋼管杭３５の傾きを算出するように構成される。【選択図】図６
