pile driver

A pile driver is a machine used to drive piles, which are postlike foundation members, into the ground. These piles, often made of timber, steel, or concrete, are essential for supporting structures, especially on unstable soils or when dealing with very heavy loads. The pile driver typically consists of a high frame that holds a pile hammer. This hammer is the heavy weight whose impact forces the pile into the earth. In addition to its primary function in construction, the term "pile-driver" can also refer to a person who operates the machine, a forceful hit or kick, or a wrestling move.123
