7. Operation

7.1 General Information

Follow all safety measures described in Chapter 3.

Operate the Diesel Pile Hammer and lead only

when they are in a perfect technical condition.

Particularly the guiding components and tripping

device should show no signs of wear.

PPE (Personal Protective Equipment) that is

required to perform any and all work shall be

provided by your employer to safely perform

this task.

Immediately halt the pile-driving operation when

a dangerous situation develops (e.g., when

unauthorized persons enter the danger zone or

in the event of damage). Operate the Diesel Pile

Hammer only after the dangerous situation has

been taken care of.

Do not carry out any repair or maintenance

work on a moving Diesel Pile Hammer.

1. Never start the Diesel Pile Hammer unless it

is resting on a pile or a specially prepared test

stand.

2. Never start the Diesel Pile Hammer with the

impact block hanging out. The impact of the

piston will transmit directly to the cylinder outer

end-ring resulting in damage of outer endring

and lower cylinder. A stuck impact block

prevents the cylinder from freely dropping on

the impact head unit (possibly due to defective

damping rings).

3. Never start a Diesel Pile Hammer which has

been disconnected from the lead or which is

resting on a skid, etc. The support device

will be destroyed and the Diesel Pile Hammer

will come crashing down causing an accident.

4. Never drive piles eccentrically. This may

cause damage to the cylinder and guide

components as well as damage and vibrations

to the material to be driven. The center line of

the material to be driven must be in line with

the center line of the Diesel Pile Hammer. This

is necessary to avoid jarring blows. Jarring

blows could cause such as but not limited to

the following:

• cracks in and deformation of the cylinder,

• vibrations in and damage to the material to

be driven,

• directional deviation for the material to be

driven.

Remedy: Use a pile helmet that is guided at the

lead and matches the pile profile. Use a pile

helmet cushion selected in an optimal manner

with respect to the material to be driven and to

the blow energy (See Chapter 9.2 “Blow energy

stages” and Appendix A3-1 “Reduction factors

for different impact head cushions”). When it is

impossible to guide the pile helmet at the lead, it

will be necessary to hold the material to be driven

at the lead with at least one pile guide.

5. Increased wear in the guide components, is

caused by rebounding impacts. This is caused

by driving eccentrically. Very hard driving of

relatively elastic piles (H-beams, spiral welded

thin wall pipe piles) will lead to damage of

the Diesel Pile Hammer especially the rubber

rings.

6. Stop the Diesel Pile Hammer if the penetration

rate is higher than 240 blows per foot. Higher

blow rates are possible, but it causes higher

wear of the Diesel Pile Hammer. BAUER-

Pileco cannot warranty parts if it is obvious

that the chosen hammer for the job was too

small.

7. The piston should not bounce into the catch

groove. If so this may damage the catch ring

piston, catch groove and attachment screws.

The safety of the Diesel Pile Hammer is thus

no longer ensured.
