GENERAL NOTES
www.dcpuk.com
The Excavator Mounted Vibrator (EMV) attachment is a perfect tool for readily
converting any suitable size of excavator into a highly productive pile driving machine.
Piles can be lifted from a stack on the ground, engaged into a powerful hydraulic grip
then positioned at will on a job site for vibrating and pushing into the ground. If the
pile line is incorrect or the position inaccurate then simply pull the piles back out.
This ability to drive and extract sheet piles has made the unit particularly attractive
to utility contractors where temporary sheet pile shoring has to be driven before
excavation can commence. Following completion of the utility installation or repair
DQGWUHQFKEDFN¿OOWKHH[FDYDWRUFDQEHTXLFNO\FRQYHUWHGWRDSLOHH[WUDFWRUWR
remove the sheets.
Once removed the sheet piles can be easily and safely laid down on the ground in a
controlled and safe manner.
The EMV220 product is extremely versatile and readily adapts to most suit
excavators from 7 to 22 tonnes, and with care up to 35 tonnes. Hydraulic power

Maximum pile lengths are determined by excavator boom length but typical pile
lengths are up to 7m (25’) or more.
The contents of this manual are intended to give guidance on the installation, safe
use and maintenance of the EMV product. It is not intended to be an exhaustive
detailing of the manufacturers detailed knowledge of the product. Technical advise
on this product is available through the manufacturer and their network of worldwide
distributors.

• There should be visual contact between operator and slinger (spotter) at all
times.
• Monitor the piling operation constantly – interrupt the process immediately
if any danger occurs.
• Do not operate the vibrator if any person is within the Danger Area
– see section 2.1.4.
• Consider machine stability at all times.

• Pay attention to the Safe Working Load of all lifting accessories at all times.
• The working area should be properly illuminated.

• The vibrator can become very hot during operation – do not touch it unless
wearing appropriate protective clothing.
Those who are in charge of, or responsible for, the use and maintenance must

Piling should only be carried out under the supervision of an appropriately

safely.
The excavator operator must ensure that his communication signals are
understood, by those on the ground, and followed. During piling operations he
must watch out for any potential hazards.

The vibrator stand must stay upright and horizontal (at all times) to avoid
personnel injury. Do not operate the vibrator if any personnel are within a 15m
(50’) radius of unit – The Danger Area.

any underground obstacles within the working area which could be dangerous to
personnel. In the case of unforeseeable contact or damage of an underground
obstacle, then work must stop immediately and the person in charge informed.

Personnel are at risk when within this area from:
• Falling piles – should the pile be handled incorrectly

• Unexpected overturning of the excavator
When transporting the vibrator, ensure it is placed correctly in the stand.
Once in place on the stand the jaws must be closed. Release the hydraulic
hoses from the excavator (the hard jaws will remain closed) and cap the hose
ends to prevent contamination. Disconnect the vibrator from the excavator.
Transporting a pile using the vibrator should only be done over a small distance,
ZLWKWKHFODPSIXOO\HQJDJHGRQWKHSLOHWRSDQGZLWKWKHOLIWLQJFKDLQ¿WWHG
Should the grip on the pile be reduced during this procedure, the excavator must
stop, and a better grip effected. Should a pile slip then the lifting chain could
snap and cause an accident. When transporting a pile extreme care must be
taken to ensure that no one is in the Danger Area and that the pile is handled in
such a way as to ensure no danger to site personnel at any time.
In order to avoid extensive transporting, have the piles laid out as close to the
point of installation as possible. Do not use the excavator with the EMV220
installed to handle bundles of piles around the job site.
