Diesel Hammers are the go-to driving force of the pile driving industry. Cost efficiency to power ratio , make the diesel hammer the must have in the foundation industry. Pileco, Inc. offers a complete line of diesel hammers from the smaller D6 to the massive D800. How does it work? Diesel pile hammers are used to drive piles into a supporting soil layer. The mode of operation is similar to that of a hammer used to drive a nail. The piston activates the pump lever during its fall. The diesel fuel is in that manner sprayed onto the surface of the impact block . The air in the cylinder is compressed as soon as the piston runs past the exhaust openings. The strongly increasing compression pressure drives the piston and the impact head below it on the material to be driven. The following occurs when the hammer impacts : the pile is driven into the soil and the diesel fuel is atomized.
