Conductor Hammering

The diesel pile hammer is an extremely rugged and reliable impact hammer. They are used for driving on different pile types like batter piles, H-beams, sheet piles as well as for driving piles in bearing layers or for the determination of pile load capacity. Diesel pile hammers can be used in all displaceable soils. Diesel pile hammers are single acting free fall hammers utilizing the principle of impact atomization. The self-ignition of the compressed fuel/air mixture is used to fire the hammer. The pile helmet is pressed onto the pile before the piston strikes, due to the compressed air in the cylinder. Consequently, damages to the pile heads are reduced. Modern diesel pile hammers are equipped with adjustable fuel pump for regulating the stroke of the piston and therefore the impact energy. This is a particular advantage when soil formations change. Optionally a hydraulically actuated fuel pump with infinite settings is available. The diesel pile hammer utilizes a tripping device to lift the piston and start the hammer. For hydraulic carriers also hydraulic tripping device is obtainable.

Explore the creative process

01

Lifting of the piston (starting)

To start the Diesel Pile Hammer the piston is lifted by means of a mechanical or hydraulical tripping device and automatically released at a certain height.

02

Injection of Diesel fuel and compression

While dropping, the piston actuates the pump lever, so that a certain quantity of diesel fuel is sprayed on top of the impact block. After passing the exhaust ports, the piston starts compressing the air in the combustion chamber. -

03

Impact and Combustion

The impact of the piston on the impact block atomizes the Diesel fuel in the combustion chamber. The atomized fuel ignites in the highly compressed air. The combustion energy moves the piston upwards.

04

Exhaust

While moving upwards, the piston exposes the exhaust ports. The exhaust gases escape and the pressure in the cylinder equalizes.

05

Flushing

As the piston continues to move upwards, fresh air is drawn through the exhaust / intake ports for flushing the cylinder while also releasing the pump lever. The pump lever returns to its starting position and the pump is charged with fuel again
