A) General Introduction
BAUER has been used several OEM Base
Carriers in BG rigs such as RH Series O&K, R
Series LIEBHERR & 300 Family CAT Hydraulic
Crawler Excavators basic machines since
1976 which successful BG7 on O&K RH6
Excavator basic machine oriented to the
market & that tradition continued until
today which we use Robex Series HYUNDAI
Excavators upper structure in our Value Line
BG rigs.
in 1998 we have started the first Bauer‐
Hyundai BH50 on standard HYUNDAI R290‐3
excavators undercarriage & superstructure
for BG15V in our Chinese facility in Tianjin.
Later on we have produced BG25C & BG20H
rigs on BH70 base carrier equipped with
Hyundai R305‐7 superstucture & UW65
Undercarriage in both Tianjin Facilitiy in
China & Aresing Facility in Germany up to
end of 2011.
Today we produce BH75 equipped with
Hyundai R335‐9 & UW65 Undercarriage for
both BG20H & BG26 Value Line in both
Tianjin Facilitiy in China & Aresing Facility in
Germany.
This tradition was followed by other
German, Italian & even recently Chinese &
Korean Kelly drilling rig manufacturers.
‐ The main advantage of this philosophy is
lower production time & cheaper total
production costs results which is an
important selling point in some areas
specially Asian & African markets.
‐ Your base carrier superstructure contains
more service & parts commonality with
normal earth moving machines such as CAT
330D/336D or HYUNDAI Robex320‐7/320‐9
which is also important when you are
intended to form your construction
equipment fleet in order to supply service &
parts availability from your nearest normal
earth moving equipment distributors which
is usual in some areas but not
recommended.
B) Base Carrier
‐ Undercarriage
BH75 base carrier on BG20H is equipped
with UW65 Undercarriage with 3.00m
shipping width designed & produced by
Schachtbau Nordhausen (SBN) our one of
our sister companies to fit with BH75 base
carrier used on BG20H & BG26H Value Line
Rigs & also former BG25 rigs on BH70 which
is can attach with our BV1300‐L03 casing
oscillator to cover up to 1.3 m bore casings.
Meanwhile we use the triple grouser
700mm tracks made by INTERTRAC & final
drive components from TRANSMITAL
Bonfiglioli suppliers.
2‐ Superstructure
BAUER BG20H based on BH75 carrier is a
modified version of HYUNDAI Robex 320‐9
for drilling rig application called R335 with
thicker 50 mm frame plates (instead of
30mm on R320‐9) as a customized special
order for Bauer.
Dash‐9 Series Hyundai Excavators were
introduced in BAUMA 2010 show for the
first time & we started to use Dash‐9
Excavators Superstructure in our BH Base
Carriers Since 2011.
Caterpillar D‐Series excavators were
introduced in INTERMAT 2006 show
considering this fact that other Italian rig
manufacturers such as IMT are using New E‐
Series or at least 336D instead of 330D
under Caterpillar MHPU Program. Mait is
still using 330D.
Meanwhile Bauer & Delmag are using
original excavator extra counterweight
ballast but Mait installed its own extra
ballast behind the MAICAT230 which does
not create a nice appearance for the
machine.
Delmag RH‐20, Soilmec SR‐60, Mait MC230
(Maicat230) are using the old CAT 336D &
330D Base Carriers which was discontinued
by Caterpillar facilities in Gosselies, Belgium
last year & production was relocated to
Caterpillar factory in China & Brazil because
of Tier4 environmental protection
regulation restrictions Since 2011.
IMT is the only one who started to use Tier4
CAT 329E on AF190 Rig but this base carrier
competes with one size smaller excavator
R290‐9 so logically is not stable as a 336D or
BH75 which are one class bigger.
Engine is lateral located on all of these base
carriers including our BH75, therefore for better
engine service access & daily checks we add
catwalks on engine hood.
Meanwhile we have our own ladder on right side
of superstructure & a catwalk platform on left
hand side of machine which normally are not
available on standard Dash‐9 HYUNDAI
excavators.
‐ Power Pack
BH75 is powered by 213kw Tier3 Cummins
QSC8.3 engine & Hyundai excavator
standard power pack including Kawasaki
Hydraulics which has simpler circuit
designation compared with Cat circuit on
336D excavators.
(Cummins QSC Catalog & Kawasaki
Pump pix.)
CAT 336D for drilling application has
261kw MHPU power pack but normally
336D in excavator configuration has
200kw engine inside.
This 261kw MHPU Power Pack is used on
several drills with rotary torque ranges from
200kNm such as SOILMEC SR‐60 (which you
don’t need 9Lit. Engine & such a power
output for a Nominal 60t weight & 200kNm
class machine considering fuel price) up to
260kNm such as IMT AF250 Tier3 rig
powered by same OEM base carrier &
power pack with 69t weight.
CAT C9 Performance Curves shows that this
engine consumes 66.1 lit./h fuel at 1800 full
throttled rpm to produce 1385 N.m torque.
This shows that because of economic
reasons Caterpillar OEM Solution Group
supplies the same 261kw MHPU power pack
for 200‐260kNm torque class drills & the
best example for that is IMT which uses
187kw power pack on 329D & not 261kw on
336D base carrier on AF190 Tier3 rig.

‐Operator’s Compartment
All D‐Generation Excavator Cabs on 329D, 330D
& 336D was introduced by Caterpillar for the first
time in INTERMAT 2006 Show in Paris but our
BH75 Cab was introduced by Hyundai for the first
time in BAUMA 2010 & can be compared with E‐
Generation Cabs from Caterpillar which was
introduced for the first time in the same Bauma
on New CAT 336E Excavator.
Over Head Guard (OHG) on our BH75 is designed
by Bauer & windshield guard is available by
Bauer or all Hyundai dealers all around the world
which already sold Dash‐9 series excavators in
their territory.
(BH75 Cab & interior & 329D cab interior
on IMT AF190 pix.)
‐ Transport
Compared with other competing rigs,
BAUER BG20H Value Line has unbeatable
3.58m tail swing radius, 3.40m transport
height & 3.00m transport width.(IMT AF190
is an exception because uses 329D instead
of 336D which is one class smaller base
carrier.)
Regarding this matter SOILMEC SR‐60 gets
the worst score in transport height with
3.65 m height & DELMAG RH‐20 gets the
worst score in shipping weight with 61t &
worst score in tail swing radius with 3.75 m
tail.
Meanwhile you don’t need to uninstall your
counterweight to reduce about 10% of
transport weight on our 57 tonner (Shipping
Weight) BG20H Value Line compared with
61 tonner DELMAG RH‐20 if you hire a 60
tonner low bed trailer.
This means you need an extra trailer to
carry counterweight for transport of a
DELMAG RH‐20 if you hire the same low bed
trailer because its shipping weight exceeds
1 t more than the trailer capacity.
C) Feature & Benefits
‐ Crowd System
BG20H Value Line is only available in Cylinder
Crowd system configuration to cover only Kelly
Drilling applications with 5.60 m Kelly Stroke &
368 mm thickness.
On SOILMEC SR‐60 rigs we can point to over
weighted 406 mm thick Kelly Bars which causes
about 10‐15% Kelly extra weight compared with
368mm Kelly used by both BAUER BG20H &
DELMAG RH‐20 which emphasizes on German
material quality instead of using more material &
weight which means that rotary has to bear this
extra weight all the times.
‐ Available Configurations
Kelly Drilling up to 51 Depth & 1.8m
Diameter
Casing Oscillation configuration to attach
BV1300‐L03 to cover up to 1.3m bore
Casing.
