(1) Steam hammer pile driver. High-pressure steam lifts the hammer head, which then falls under its own weight to strike the pile head and drive the pile into the ground.
　　(2) Diesel hammer pile driver. Fuel explosion drives the piston, and the explosive force strikes the pile head to drive the pile into the ground; suitable for driving various types of precast piles.
　　(3) Vibratory hammer pile driver. The mechanical vibration force of the pile hammer drives the pile into the ground; suitable for precast concrete piles, steel sheet piles, etc. with relatively low bearing capacity.
　　(4) Static pile press. The pressure generated by a mechanical winch or hydraulic system presses the pile into the soil under continuous static pressure; used for various types of precast piles with general bearing capacity.
