    • A drop hammer for driving a pile comprising a ram member supported within a housing chamber for movement relative to the housing member between the lower position and the upper position and a lifting system for moving the ram member from the lower position to the upper position. When the lifting system raises the ram member above a preload position, ambient air substantially freely flows into and out of the housing chamber through a vent port. When the ram member falls below the preload position, fluid is prevented from flowing through the vent port such that ambient air within a preload chamber portion of the housing chamber compresses to create a preload force that is transmitted to the pile. When the ram member moves into the lower position, an impact force generated by the ram member is transmitted to the pile.
    • 一种用于驱动桩的落锤,包括支撑在壳体室内的冲头构件,用于相对于壳体构件在下部位置和上部位置之间移动;以及提升系统,用于将压头构件从下部位置移动到上部位置。 当提升系统将压头构件升高到预加载位置之上时,环境空气通过排气口基本上自由地流入和流出壳体室。 当柱塞构件落在预压位置以下时,防止流体流过排气口,使得壳体室的预压室部分内的环境空气压缩以产生传递给桩的预载力。 当冲头构件移动到下部位置时,由冲头构件产生的冲击力被传递到桩。
