Hydraulic Tube Extracting Equipment
Our tube extracting machines are designed for ex-
tracting tubes of 340 to 1500 mm dia. By means of
an attachment, even wide flange beams and sheet
piling sections can be extracted.
The essential advantage of the machine is the com-
pact construction. The complete drive including the
controlled hydraulic pump is incorporated in the
base of the machine which means that no obstruc-
tion by hydraulic hoses will occur on site. In order
to obtain a weight as low as possible a high-
strength steel is used and the complete welded
construction is stress-relieved prior to machining.
The special construction of the four-link gripping
collar enables work to be carried out as close as
250 mm to a wall. With easily assembled collet in-
serts the collar diameter can be changed without
any problem.
The installed heating enables the use of the machi-
ne even in low temperatures.
A hydraulic, fully automatic uncoupling clamp has
been developed for the tube extracting machines
which enables easy coupling and uncoupling of the
form-work tubes.
Due to the simple, clear layout of the control table,
operating personnel require only a brief introduc-
tion.
“Leffer” tube extracting machines with uncoupling
device and “Leffer” form-works tubes have proved
themselves in the toughest utilization by the leading
european contractors in special deep foundation.
