The piling machine is composed of pile hammer, pile frame and ancillary equipment. The pile hammer is attached to two parallel vertical guide rods (commonly known as gantry) in the front of the pile frame and lifted with an lifting hook. The pile frame is a steel tower frame, and a hoist is arranged in the rear to lift the pile and the pile hammer. There is a guide frame composed of two guide rods in front of the pile frame to control the direction of piling, so that the pile accurately penetrate into the formation according to the design orientation. The basic technical parameters of the piling machine are the impact part weight, impact kinetic energy and impact frequency. The power source of pile hammer according to movement can be divided into drop hammer, steam hammer, diesel hammer, hydraulic hammer and so on.
