Hydraulic hammer

o Modern type o# piling hammer

o Used in place o# diesel and air hammers #or

driving steel pipe$ precast concrete$ and tim"erpiles&

o More environmentally accepta"le than the older$less e8cient hammers as they generate less noise

Hydraulic press-ino Specialty e!ipment which installs piles !sing hydra!lic ramsto press piles into the gro!nd&

o Pre#erred where vi"ration is a concern&

o There are press attachments that can adapt to

conventional pile driving rigs to press , pairs o# sheet piles at atime&

o Additional types o# press e!ipment sit on top o# e(istingsheet piles and grip onto previo!sly driven piles&

o Allows #or greater press6in and e(traction #orce to "e !sedsince more reaction #orce is developed&

o The reaction "ased machines operate at only 9:d3 at

Vibratory pile driver/extractor

o 'esigned in s!ch a way that hori5ontal vi"rations cancel o!t$

while vertical vi"rations are transmitted into the pile&

o The pile driving machine is li#ted and positioned over the pile "ymeans o# an e(cavator or crane

o 1i"ratory hammers can either drive in or e(tract a pile

o 4ydra!lic ;!id is typically s!pplied to the driver "y a dieselengine powered p!mp mo!nted in a trailer or van and connected

to the driver head thro!gh a set o# long hoses&

o 4ammers are availa"le with several di7erent vi"ration rates$ranging #rom a"o!t ),
