2.2 Modules MD1
•MG41 4-speed gearbox
•ST3 (QDC-)Spindle unit for MG41 (quick disconnect coupling for drill bit optional)
•ERMD1 Extension Adapter for MD1 (Extends capacity by Ø 190 mm per adapter and up to 3
pcs can be used.) - Accessory
MG41 ST3 ERMD1
2.2.1 MG41 Gearbox
The Pentruder drill system has a 4-speed gearbox to offer a wide speed range for various drill bit
diameters. Performance and safety is increased as the spindle speed cannot be increased over the
adjusted speed during drilling.
2.2.2 ST3 (QDC-)Spindle unit
The concept with exchangeable spindle units makes it possible to get a very wide spindle speed range with
only one drilling machine. There is also a ST2 Spindle Unit with lower spindle speeds but it should not be
used together with the MDU9 Drive Unit as the torque will be too high for the drill spindle. See chart on
page 29 for spindle speeds with the MDU9 Drive Unit and ST3. The spindle units can be ordered with or
without Quick Disconnect Coupling (QDC) for the drill bit.
2.2.3 ERMD1 Extension adapter MD1
When drilling big diameter holes over Ø 600 mm (23.6”) an extension adapter must be used to extend the
distance between drill column and spindle, giving more clearance for bigger diameter drills. Each adapter
extends the drill unit 90 mm (3.5”) further away from the column, i.e. gives additional clearance for a 180
mm (7”) bigger drill bit. Up to 3 pcs can be used together.

2.3 MDU9 Modular Drive Unit – NTGRA®and MDUMR-MG41
•MDU9-HF-NTGRA®Modular Drive Unit with up to 9 kW output power.
•MDUMR-MG41 Adapter for MDU Modular Drive on MG41.
The MDU9 Modular Drive Unit can either be used as “stand alone” unit which together with a spindle unit is
bolted on any drill stand which is rigid enough to handle the high power of the MDU9.
The Modular Drive Unit accepts both a very wide input voltage range, 400-480 Volt 3-phase power and 230
– 250 Volt 1-phase power. To switch between 1-phase and 3-phase power all that is needed is an adapter
cable. An adapter cable is used for 1-phase input.

•No mounting, for instance change of drill bit, may be performed on the
drill rig unless it is disconnected electrically from the mains.
•Safety regulations at the work place must be followed as well as the
safety regulations of the operator’s manual for the drill motor used.
•All persons working with, or in the proximity to the drilling rig should wear
safety equipment, i.e. protection helmet, protection shoes, gloves, eye
and ear protectors. Other safety regulations at the work place must be
followed. The noise level at drilling might lead to permanent hearing
disorders if not ear guards are worn.
•The operator should have good supervision over the drill system and
inform passing persons about possible risks.
•Unauthorized persons shall not be within the risk area (the area around
the drill unit).
•The drill bit may not be touched when the drill motor is in operation.
•Never connect the hydraulic hoses to either drill unit or power pack while
the power pack is running. The power pack must be disconnected from
the power supply by removing the 32 or 63 Amp plug and cable from the
power pack before any connections are made.
•The power pack must always be switched off and the 32/63 Amp plug
and cable disconnected from the power pack before any kind of service
is commenced.
•Mounting and dismounting of the drilling unit and drill bit may only take
place when the drill motor is disconnected from the power pack by
removing the 400V power cable.
•The power pack is water cooled and must be drained from water when
the ambient temperature is in the proximity of or below 0 degrees
Celsius.
•The electric motor of the power pack is water cooled and the water
pressure must therefore be limited to max 5 bar. The incoming water
supply may only be connected to the lower connection on the power
pack. The quick disconnect couplings may not be replaced with
couplings that are not fully open when disconnected.
•
Always lift the drill unit ergonomically correct. The Pentpak is not
provided with hooks for lifting. Should this unit need to be lifted with a
crane, this should only be done after permission and instructions have
been given by a person responsible for safety on the site. Contact your
sales agent for instructions on how the lifting can be done in the best
way.
•
The base plate must always be securely anchored to perform safe
drilling.
•Never run the drill unit without water cooling. The seals are quickly worn
and water leak can occur. Should the cooling water seize to function,
stop the machine immediately.
•Before drilling is commenced all persons involved must know how the
emergency stop button is working.
•Remember always to cover drilled holes so that no person falls down
and hurts himself.

•Only connect the po
wer pack to the Pentruder drill system or such
equipment which has been manufactured or approved by Tractive AB.
•Should the drilling machine fall down from the ceiling it could cause
severe injuries. Keep away from the working area of the drilling machine.
•Don’t use any extension or lever to get a higher feeding power.
•A heavy core in a drill bit which rotates outside of the drilled how can
lead to heavy vibrations so that the drilling machine can come loose
from the anchor. Stop the drill bit shortly before it comes out of the drilled
hole.
•Re-bars which have been cut off can be stuck between the core and the
drill bit and block and/or damage the drill bit. Before the drilling is
commenced, make sure that no segments are left in the drilled hole.
•Should the drill bit get stuck, turn off the drill motor and unplug it. Use a
wrench to move the drill bit forwards and backwards until it is
disengaged and can be pulled out of the hole.
•When drilling upwards, make sure the core cannot fall down by securing
it properly. Rope off the working area.
•Only change gear when the main HF-motor is stopped.
•The power pack must only be operated when in an upright position.
