THE HANDLING OF VARIOUS PILE TYPES

and is important enough to warrant careful attention. delivered by pressure through hoses and pipes. The soil is
eroded below the tip of the pile, often permitting penetration
merely by the dead mass of the pile and the hammer. It is
particularly effective when displacement type piles are to
be driven through dense fine sand to desired penetration in
firm soils below, but should not be used in embankments or
other areas where it would tend to destroy densities which
have been purposely built into the soils.
Also, unless good judgment is exercised, jetting could
destroy the bearing value of piles already driven, especially
when piles are closely spaced or when they tend to drift
away from their prescribed course. Water jetting has been
useful as an aid to driving displacement types of piles in sand
formations in streams where water is readily available and
pile penetration is equally as important as bearing capacity.
Concrete piles must be handled with care. It is very easy
to cause cracks by indifferent handling. Cracks may open
up under driving, and may spall and powder to such an
extent as to seriously lessen the strength or life of the pile.
Shock, vibration, or excessive deflection should be avoided
by using proper equipment and thoughtful handling. When
piles are picked up with adjustable slings, blocking should
be used to prevent breaking off the corners. Unless special
lifting devices are attached, the pick-up points shall be
plainly marked on all piles before removal from the casting
bed and all lifting shall be done at these points. If the piles
have been allowed to dry after curing, they shall be wetted
at least 6 hours before being driven and shall be kept moist

vibration from a vibratory hammer and the damage that
these hammers put on cranes. Pile Driving Solutions Inc.
became the official distributor of the Tunkers Vibratory
Damper in January 2015. This product now allows the use
of hydraulic cranes to be used for vibratory hammer work
with little to no impact on the crane. It provides extended
protection to all cranes from the vibration put out by the
The damper minimizes most vibration to the crane due to
the vibration put out by vibratory hammers. It maximizes the
safety of the crane work being done, provides little to no
maintenance, minimal set up, decreases extraction time,
and has a potential ten year life expectancy based on the
number of hours it’sused.
The damper can be used on all model cranes.
Manufacturers like Liebherr require that dampers or isolators
be used when vibratory hammers are placed on LR model
“The damper is engineered to absorb the vibration
from the vibratory hammers, help job run smoother,
reduce downtime and provide more safety for the type
of operations. I’ve been around cranes my whole life and
the damper by far is the best investment you can make to
protect your cranes from the vibration put on them. This has
opened up a new market for crane rental companies and I
