HPSI - Lead Systems for Continuous Flight Auger (CFA) Projects

U-type leads, also referred to as box leads or steam leads, are designed in a 'U' shape to provide guiding rails for hammers within the open section of the lead. These leads are particularly effective for use with continuous flight auger (CFA) techniques, where they assist in the excavation of holes and enable concrete to be injected under pressure while the auger is being retracted. This method offers substantial benefits in projects requiring precision and stability in foundation work. The leads are available in standard and metric units, with weight variations influenced by the assembly of shorter sections. Such configurations ensure adaptability and customization for diverse construction needs, optimizing performance and efficiency in piling applications.
