The Deltabase 520 Multipurpose Drill Rig
is designed for optimum performance for:
The DB 520 is a most versatile drill rig
suitable for all geotechnical applications. It
can be mounted onto a crawler, small
sized trucks or trailor.
The unit is powered by a 4 cylinder Deutz
engine or by PTO from the truck engine.
The drill rig has the capacity to drill in an
angle of 90 degrees in the axle of the rig.
Further to this 90 degrees capacity the
mast can be swiveled in a 360 degree
angle perpendicular to the axle of the rig
(option). This movement is made by
hydraulic cylinders which allow to the turn
the mast for 90 degrees in one movement
(45 degrees to each side). The full turn is
obtained by moving the cylinders to
different attacks.
The mast has a mast dump facility
allowing to adjust the distance between
the ground and the bottom clamps.
All hydraulic cylinders are mounted with
non return valves.
The stabilising cylinders at the corners of
the rig can be operated independently.

Various gauges enable the operator to
maintain exact control.
The drill rig is equipped with a double
clamping system at the bottom of the
mast. The clamps are for holding and
breaking drill rods, casings and tools. The
upper one of the two camps can be
hydraulically turned in order to break
thread connection.
In order to avoid damages on drill rods,
the clamping force can be adjusted by a
pressure control, valve, a flow regulator
and a pressure gauge.
The power head is of hollow spindle type.
It is built with a floating spindle, minimising
the wear and damage on the drill rods
threads during making and breaking the
threads.
As an option an hydraulic chuck can be
mounted.
The head is powered by a hydraulic motor
VOLVO and a HURTH gear box with
speed reducer resulting in 8 gears. The
change between the gears is manually.
The rig is equipped with an emergency
shut down system via two emergency
stops shutting down feed and rotation
within minimum delay.
The maximum torque generated by the
head is 6.000 Nm, maximum RPM are
600.
To make room for operating rods and
casing with the hoist the power head can
be shifted laterally by a hydraulic cylinder.
As an option the drill rig can be equipped
with an automatic SPT.
As an option a tip out device for the drill
head is available, enabeling the operator
to put the drill head into horizontal position
resulting in a easier rod handling.
The control panel is located on the right
side of the drill rig (mast in front)
