The main body of the diesel hammer pile driver is also composed of a cylinder and a plunger. Its working principle is similar to that of a single-cylinder two-stroke diesel engine. It uses the strong pressure generated by the explosion of atomized diesel injected into the combustion chamber of the cylinder under high pressure and high temperature to drive the hammer head to work.

Screw pile drivers are mainly composed of power heads, drill rods, columns, hydraulic crawler chassis, slewing structures, winches, operating rooms, electrical systems, hydraulic systems, and shipping mechanisms. In working conditions, the hydraulic system can be manipulated to achieve walking, slewing, lifting and lowering columns and pile driver alignment. During operation, the power head drives the drill rod, the drill bit rotates, and the winch controls the lifting and lowering of the drill tool. The soil cut by the drill is transported to the ground by the spiral blade. Drill to the designed depth and lift the drill to form a hole. According to the requirements of the construction method, the pile can also be formed by pressing concrete (or mud) while lifting the drill.

A diesel pile hammer uses the impact force of a diesel hammer to drive piles into the ground. A diesel pile hammer is essentially a single-cylinder two-stroke engine. It uses diesel to burn and explode in the cylinder to do work. It pushes the piston to reciprocate in the cylinder to hammer and drive piles. A diesel pile hammer and a pile frame together are called a diesel pile driver.
