4.2 FUNCTIONS
Rotation.
The auger is rotated by two axial piston
motors. TAD-30s has two different speeds for rota-
tion. Higher speed employs only one of the motors
with maximum torque of 15.000 Nm. Lower speed
mode engages both motors and delivers 30.000 Nm
of torque.
Lowering and raising the auger.
Telescope and el-
evator mechanisms are used for lowering and raising
the auger during drilling. Keep the auger paralled
and centered to the bore at all times. Careless mov-
ing the boom or the arm may cause bending forces
to the telescope lead to break downs.
Movax TAD30-2 soil drill has telescopic kelly bar
with two moving extensions. Movement is imple-
mented with a hydraulic cylinder. The mechanism is
working two ways thus enabling the hydraulic push
and pull. During the drilling work the kelly bar can
be also released to floating mode.
Elevator
refers to a lift mechanism on between main
body and a part that links the soil drill to the exca-
vator. Elevator is moving the drill up and down by
hydraulic cylinders. This can be used for reaching
the maximum depth but also for drilling or pulling
out at any depth as it creates same direction linear
movement as the telescope.
Side tilt.
The soil drill tilts 30º both side ways. This
movement works with two hydraulic cylinders. The
tilt is used to straighten the drill when the excavator
is on slope or uneven surface. Tilt can be also used
for raked drilling.
