Pintsch Bubenzer charting a new path
Pintsch Bubenzer is investing in a
new generation of brakes while
developing MYPort into a crane
and terminal service company
Pintsch Bubenzer GmbH (PB) recently
held a 10th anniversary celebration
for its Malaysian subsidiary
PB MyPort Sdn Bhd (PBMY).
In its short history MyPort has
grown from a strategic Singapore
branch office to what PB describes
as a “global centre for crane braking
systems.”
PBMY now has 32 employees,
including eight service engineers
and eight mechanical and
electrical engineers - more service
personnel than PB has in Germany
- and is extending its operations
well beyond brakes. It
operates from two facilities, a
training centre at Tanjung Pelepas
and a new building at nearby
Gelang Patah.
This requires considerable investment,
and raises the question
whether the Schaltbau Group,
which owns PB through Pintsch
Bamag, has a wider strategy that
may eventually lead to starting
brakes production in Malaysia.
PB’s managing director
Markus Topp said, however, that

the company is committed to
maintaining manufacturing in
Germany. The company wants to
be at the forefront of developing
new braking technology, and Topp
does not believe this is possible if
manufacturing is sent offshore.
Cost is of course important,
but PB has addressed it by investing
in capital equipment to make
manufacturing less labour-intensive,
including machinery that
performs multiple processes, and
reconfiguring its factory so one
operator controls two machines.
This strategy requires capital
and commitment, not just to invest
in new equipment, but to
develop the supporting labour
force. PB needs workers with different
skills than previously, and
has actively engaged local universities
and polytechnics to ensure
it positions itself as an attractive
option for young people.
New centre
PB has just opened a new research
and development centre near its
manufacturing facility in Kirchen-
Wehbach. It will be able to meet
increasing demand for documented
tests as well as producing
new products. It is equipped with
dyno stands for high speed brakes
and test benches for storm and
emergency brakes.
For the container crane market,
the first new product will be
an electro mechanical wheel brake,
scheduled for release later this year.
Current wheel brakes are hydraulically
released and terminal operators
would like to eliminate
hydraulics as far as possible. PB has
developed several prototypes and
is now finalising a design to launch
on the market later this year.
Go with the cranes
PB’s strategy with MyPort, said
Topp, is driven by the need to take
sales and service directly to the
Asian market, which is now too
big to be handled effectively out
of Germany. In 2011 the company
acquired 95% of PBMY and last
year opened an office in Shanghai.
It also has a US service and
training centre (PBUS) in
Flemington, New Jersey.
Topp explains that PB has developed
a policy of “know-how
transfer” so local companies can
provide a full service offering.
Dealing with brake issues requires
a wide range of skills. Brake wear
is frequently caused by alignment

issues in rope drum drive systems
and, on some cranes, structural
deflection in the machinery house
floor. PBMY has built up considerable
expertise, including a laser
alignment system, to troubleshoot
and fix braking problems. This includes
selecting couplings and
other components that match the
wear characteristics of the crane
as well as the technical specifications
of the drive system.
In the frame
At a component level PBMY and
PBUS are equipped and certificated
to rebuild brakes and thrusters, so
components no longer have to be returned
to Germany for this service.
This has enabled them to enter
service contracts and “frame
agreements” covering servicing
and rebuilding of older brakes.
PBUS has a frame agreement with
the Port of Houston Authority
and PBMY has a five-year agreement
with Northport and a 2-year
agreement covering PSA Singapore’s
huge crane fleet. Brakes that
are 15 years old, including brakes
from other suppliers, are removed
from service and rebuilt, tested and
certified locally.
PBMY is now moving beyond
brakes and evolving into a wider
service company. It is a partner
with Siemens in the Siemens-
Myport Regional Crane Training
Centre at Tanjung Pelepas, which
can train and certify a technician
in Siemens drives and PLCs. It also
offers gearbox rebuilds on Stiebel
gearboxes, which are used in the
Siemens ECO RTG system.
PBMY’s managing director
Suzannah E Jamain said drive refurbishment
has huge potential.
There are many old GE drives in
Malaysia on cranes from Impsa,
Doosan, Favelle Favco and Muhibaha.
PBMY has worked with terminals
to keep these up and running,
but many are now at the
point where they need replacing.
PBMY is also working further
afield, and recently completed a
project to retrofit two Mitsubishi
STS cranes in Dubai, replacing GE
DC drives with a Siemens system.
In Malaysia, PBMY is moving into
the container yard, where it offers
installation and commissioning for
the Stemmann Technik E-RTG
conductor bar system, and it is
developing a DGPS-based container
position system and wireless
LAN installation and support.
SOS message
The first two cranes with the SOS
electro mechanical snag and over-
CARGO HANDLING
Northport Klang is fitting its new STS cranes with the Pintsch Bubenzer
Malmedie SOS snag load protection system
load prevention system in Asia are
now undergoing commissioning
at Northport in Port Klang, Malaysia.
The cranes are the first of
five Northport has ordered from
Hyundai Samho. Northport’s assistant
general manager, equipment
and maintenance, G
Sundaraja Perumal believes that
there are two main benefits from
the SOS system: a reduction in
crane weight by eliminating hydraulic
snag cylinders at the boom
tip; and reduced maintenance.
The first two cranes will operate
on a quay with a wheel limit
of 40t per metre. Northport
wanted twin lift capability and its
consultant, Casper Phillips & Associates,
designed a crane with a
55t SWL over the 40m outreach
weighing just 1250t (with 10
wheels per corner to spread the
load). Every opportunity to save
weight was important.
Most snag events at Northport
actually happen on smaller, older
vessels with damaged cell guides.
Northport has hydraulic anti snag
systems on other cranes and
Sundaraja said they require regular
maintenance, particularly as
they age and start to leak. He
would like to eliminate hydraulics
wherever possible and, as well
as the SOS system, the new cranes
will have a mechanical screw type,
trim, list and skew system.
Brake monitoring
Another area where Sundaraja
expects significant benefits is having
the brake monitoring system
integrated with the main crane
monitoring system (CMS). PB’s
latest computer brake monitoring
system, called CMB2, connects to
the crane PLC via Profibus and is
pre-integrated with the CMS before
the crane is delivered.
Sundaraja said Northport has
changed its approach to buying
cranes. It the past it relied on the
OEM to engineer the drive, but
now it requires the drive supplier
to engineer, install and commission
the drive itself. It is taking a
similar approach with brakes and
PB is designing the whole braking
system and maintaining it under
its existing 5-year agreement.
Northport previously tried to
outsource maintenance to a general
service company, but has not
been happy with some of the results.
“What we are doing now, said
Sundaraja, “is identifying the critical
components where we want
the component suppliers to be
involved in regular inspections and
maintenance.” ❏
