have a force pump, a guide frame‌—‌something like an ordinary pile-driving machine 25 or 30 feet in height, with a grooved pulley at top in which the chain or rope runs so that one end can be attached to the pile flange either by jaws or temporary bolts, and the other to a crab winch, which, with the guide frame, is used for lowering and keeping the pile in position, and stay the top of the guide frame by ropes to short piles driven into the ground‌—‌and a hose and two levers, with a collar to grasp the pile so as to rotate it, you have about all the special plant that is wanted.
