Abstract
A new hammering system with electromagnetic power for dynamic pile testing. The basic working principle of the hammering system is as follows: when an internal coil is energized, a magnetic force is generated to attract tightly, via a magnetic conduction panel, an adaptive weight hammer disposed in contact with the surface of the panel; when the internal coil is de-energized, demagnetization occurs, and the weight hammer falls instantaneously to impact the pile top, thereby achieving the effects of a stable weight hammer and quick attraction and falling of the hammer. A clamping scale is arranged inside an adjustment section of a guide frame. A falling height of the weight hammer may be selected arbitrarily.
