General Remarks
RDM/RDM-M
RDM-M 2000 in operation
The hydraulic full 360 degree turning casing rotators
are economically used to construct bored piles with
the full casing method under hard soil conditions.
The continuous cutting of the hard ground guarantees a boring speed satisfying today's requirements, even for compressive resistance of up to
2500 kg/cm2.
The full 360 degree continuous turning of the casing
minimizes the friction compared to the oscillating
method allowing the casing to drill down to 100 m
depth with the casing rotator machines.
The first casing is fitted with carbide bits which can
be adapted to the requirements of the soil conditions offering major advantages when coring
through hard rock layers or when constructing
secant walls.
The full 360 degree continuous turning of the casing
by powerfull hydraulic motors eliminates the possibility of pile misalignment.
Beyond that, the casing rotators are especially suitable for the construction of full casing displacement
piles because of the ability to apply very high
torque, push down and lifting forces on the casing
which is not possible with the known drilling rigs.

The casing oscillators can be kept in continuous operation with the specified torque and forces.
The hydraulic casing oscillators
have been designed in accordance with the latest technical
know-how. Extremely sturdy construction guarantees cost-effective use on site. By means of exact statical calculations in conjunction with higher quality material, an optimum conformity of
loads, weight and material
strength is achieved. The internal
wielding stresses – difficult to determine for static calculations,
which would affect the construction considerably – are eliminated
by means of stress relieving prior
to machining. A prominent feature
of the equipment is the clamping collar consisting
of five links operating on the boring implement. The
individual links surround the casing like a chain so
that a consistent surface pressure is exerted on the
casing circumference. In addition, the large height
of the collar (600 to 800 mm) prevents any damage
to the casings. By means of easily exchangeable
reducer pieces the oscillator can be converted,
within a few minutes, to a smaller casing diameter.
The collar opens uniformly and enables unproblematic insertion of the casing with the cutting shoe.
Another advantage of the machine is the low height
on the excavator side. The excavator can be swiveled by 360° in coupled condition.
VRM 3000 in operation

Attachment at the excavator itself is torque rigid
and guarantees the transmission of the full rotating
movement of 25° to the casing if the excavator is
firmly situated.
The design and construction of the casing oscillator
is based on the experience of many years of co-operation with companies specializing in pile foundations. In view of the high costs which would result
from a breakdown of the equipment on-site, great
emphasis has been put on exeptionally sturdy construction.

The casings are designed to create cased holes down to a depth
of 35 m. Especially for the construction of bored piles by rotary
drilling rigs precisely fitting casing
joints guarantee a fast placement
and bolting of the casings as well
as ideal power transmission.
For a diameter of up to 1500 mm we recommend double-walled casings. For
weight reasons single walled casings
can be used for larger diameters. The
bottom casings would always be double-walled.
Because of the further development of hydraulic casing oscillators (type VRM) and the new development of hydraulic full 360
degree turning casing rotators
(type RDM) we are now in a position to sink bored piles into
depths of 100 m. In order to meet
the greater demands facing casing columns operating at such
depths, »heavy duty type« casings have been developed.

The Hydraulic Spherical Grab type HLKG is used on
jobs, where drilling has to be carried out free of vibrations and/or where partially cased or uncased
drilled shafts are to be produced.
The high deadweight in conjunction with the high
closing force ensures a high efficiency. The hydraulic turning device enables the grab to be turned
100° to ensure a calibration of the borehole.
To recognize and correct any deviation of the vertical excavation direction, all hydraulic spherical
grabs are equipped with a two-axis inclination sensor. The inclination sensor values are monitored inside the operator’s cabin. For uncased drilled shafts
the grab type HLKG “CD” is used. The jaw dimensions are adapted to the respective shaft diameter.
