Structure and operation the system
Elpress systems consist the
following parts:
• hardened steel tip
• leading rod
• extension rod
• driving sleeve/impact sleeve
• earth line (not supplied Elpress)
This feature simple
• the earth line inserted into the
hardened steel tip and clamped the
leading rod. NOTE: Do
not rotate the driving sleeve during the
work.

power hammer should used.
• the extension rods are fitted with a
guide pin, which during work pushed
into the preceding rod.
In the event interrupted driving, start
again distance least 1. When the appropriate
value reached, driving interrup-

withdrawn (and can therefore be
reused).
Hard and rocky soil- steel rod mm

into the hardened tip with the leading
rod. Preferably measure the earthing resi-
stance continuously while driving down
the earth line.
- the rod continues and the line stops; the
line has come loose and can pulled up
or the tip has folded.
