3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100:2010,
!EN 16228-1:2014+A1:2021" and the following apply.
NOTE Examples are given in Annex A of !EN 16228–1:2014+A1:2021".
3.1
rotary percussion hammers
equipment to drill holes into the ground, where the rotary drive has an additional impact hammer
Note 1 to entry: The rotary percussion hammer can be mounted at the end of the drill stem outside the hole on
the leader of the drilling and foundation equipment. The range of the impact frequencies is usually between 20 Hz
and 60 Hz.
3.2
down the hole hammers (DTH-hammers)
device in which the percussion mechanism is located directly behind the drill bit
Note 1 to entry: The drill pipes transmit the necessary feed force and rotation to hammer and bit plus
compressed air or fluids for the hammer and flushing of cuttings. The drill pipes are added to the drill string
successively behind the hammer as the hole gets deeper. The hammer piston strikes the impact surface of the bit
directly, while the hammer casing gives straight and stable guidance of the drill bit. This means that the impact
energy does not have to pass through any joints at all. The impact energy therefore is not lost in joints allowing for
much deeper percussion drilling.
3.3
impact hammer
leader-guided or free-riding equipment to drive pile-elements by high-force striking action into the
ground
Note 1 to entry: The equipment can be actuated by hydraulic or pneumatic energy, or by internal combustion,
e.g. diesel hammer or a free falling weight lifted by a winch.
3.4
static pile pushing/pulling device
equipment to push or pull piles, mostly sheet piles, into or out of the ground or vice versa, by static
pushing pulling forces, which are commonly actuated by hydraulic energy
Note 1 to entry: The equipment is fastened via clamps to more than one pile and is pushing/pulling one pile
with the actuator und using the other clamps as thrust bearing. This equipment can be mounted on a leader of a
drilling and foundation equipment or can be self-riding on top of the piles.
3.5
sonic drilling device
equipment which superposes rotary drilling with vibrations at a high frequency
Note 1 to entry: The vibrations are mostly generated within the drill head and can be controlled by the operator
to suit the specific conditions of the soil/rock geology. Resonance magnifies the amplitude of the drill bit, which
8
---------------------- Page: 10 ----------------------
SIST EN 16228-7:2014+A1:2022
EN 16228-7:2014+A1:2021 (E)
fluidizes the soil particles at the bit face, generating a fast and easy penetration through most geological
formations. The frequencies used with this method are normally between 50 Hz and 120 Hz. This equipment can
be connected at the leader of a drilling and foundation equipment.
3.6
casing oscillator/rotator
equipment to drive in or push out casings with great diameters by low-speed rotation and high
push/pull force
Note 1 to entry: This equipment can be connected to the undercarriage of the drilling and foundation
equipment. Some types of casing oscillator/rotator can be used as standalone equipment, controlled from the
operator’s position of the drilling and foundation equipment, or by an extra operator at the casing
oscillator/rotator. In case of combination with the undercarriage, the drilling and foundation equipment has to be
able to resist the reaction forces coming from the torque and the pushing/pulling forces of the casing
oscillator/rotator. The movement of the clamp system holding the casing can be intermittent, changing the
moving direction after each movement interval or can be a more or less turning movement in one direction.
3.7
rotary drilling drives
equipment to actuate the rotating drilling stem, which is normally mounted at a leader or mast
Note 1 to entry: Rotary drilling drives are rotating the drill stem continuously in one direction.
3.8
deep vibrator
equipment to densify the soil by using a vertical into the ground driven lance, which is driven by an
unbalanced mass at the bottom part of the lance
Note 1 to entry: The hole which is generated by densifying the ground is filled with soil improving material such
as gravel. This material can be fed by a special material tube alongside the deep vibrator or by filling the emerging
hole with gravel by loaders. The apparatus can be rope suspended or guided on a leader or mast. The vibrations
are normally generated by hydraulic or electric power and have a usual range between 25 Hz and 60 Hz.
3.9
vibrators
equipment to install or extract piling elements by high-frequency oscillation into or out of the ground
Note 1 to entry: The force is generated by vibrations, which have a usual range between 20 Hz and 50 Hz. These
vibrations will soften the ground; the weight or pull down or pulling force will move the elements. The vibrations
are generated by unbalanced weights, which are driven by hydraulic or electric power. Vibrators can be mounted
at the leader of a piling rig or can be free riding at top of the element, suspended by a rope or connected to a
cardan/universal joint to the carrier machine.
3.10
connection of parts
installation of interchangeable equipment onto drilling and foundation equipment, earth-moving or
agricultural equipment
4 List of additional significant hazards
Clause 4 of !EN 16228-1:2014+A1:2021" applies with the following additional Table 1.
Table 1 of !EN 16228-1:2014+A1:2021" and the additional Table 1 in this document contain all
hazards, (hazardous situations and events), identified by risk assessments as significant for
interchangeable auxiliary equipment and which require action to eliminate or reduce risk.

5.2.2 Casing oscillators/rotators
The controls (including emergency stop) shall stay at the operator’s position, or if there is a separate
control station, there shall be an additional emergency stop at the operator’s position.
5.2.3 Vibrators
Suspension devices of vibrators shall isolate the transmission of vibrations to the carrier machine.
The maximum allowable pulling force shall be clearly marked on the vibrator.
In case of failure or breakage of the spring elements, a connection between vibrator and suspension
device shall remain in order to prevent broken parts falling down.
5.2.4 Clamping devices for connection of pile elements to the driving tool
The clamping force of the clamping device for vibrators shall be in any operating condition at least
1,2 times the actual vertical force.
This condition is deemed to be met when the clamping force is at least 1,2 times the theoretical
maximum centrifugal force under no load.
The clamping force for static pile pushing or pulling devices shall be at least 2 times the maximum
pulling force.
The pressure developed in the hydraulic system shall provide at least the required minimum clamping
force, and a device shall be included in the system for maintaining automatically the hydraulic pressure
at the minimum required value as long as the clamp is closed.
All clamp systems shall have a protective device which prevents clamps from being unintentionally
opened during operation.
Clamps shall have a safety device (e.g. check valve) maintaining them in the closed position even in case
of total loss of pressure in the hydraulic lines.
!The clamp hydraulic cylinder pressure shall be indicated on a pressure gauge or an indication
device.
Clamping devices shall be made such that they facilitate the pitching of the pile into the gap of the
clamping device, e.g. by guiding plates or chamfers at the open end of the gap.
Interchangeable equipment equipped with a clamping device for driving sheet piles or piles shall be
fitted with an anchoring point to which a device (e.g. rope or chain) can be attached to secure the sheet
piles or piles. This does not apply to cast in situ system."
5.2.5 !Excavator mounted add-on auger drives
Add-on auger drives mounted on the boom of an excavator are excluded from the requirement of
guarding the auger. EN 16228-1:2014+A1:2021, 5.23.2 does not apply."
5.3 !Noise
EN 16228-1:2014+A1:2021, 5.27.2 applies with the addition of specific test code specified in
Annex A."
