M
ike Chamberlain, marketing and
commercial executive at this
leading local repairer of rotating
electrical and mechanical equip-
ment, points out how critical it is to ensure the
highest degree of accuracy when balancing
rotatingmachines as thiswill minimise vibration
levels thereby increasing reliability and reducing
maintenance costs.
The 32 t Schenck HM7 U/S balancing ma-
chine, locatedatMarthinusen&Coutts’ 9500m²
high-techworkshopinCleveland,Johannesburg,
is in constant use. “Our customers, which include
major local and international OEMs, benefit
significantly through access to an independent
balancing service offering with this level of ca-
pacity and quality.”
The HM7 U/S balancing machine has a mea-
suring range between 100 and 5 000 rpm. It is
9.0 m long, has a journal size of 400 mm and
a swing of 2.4 m. The machine is fitted with a
CAB 920 H computer measuring system with
advanced functionality.
“This state-of-the-art technology makes
changeovers to new rotor types quick and
straightforward, and the machine is capable of
balancing larger high-speed rotors dynamically
at full operating speed,” Chamberlain says. He
adds that, on occasion, and depending on the
design of the rotor and the individual customer
requirement, balancingcanbedoneat 10%over-
speed or more if required.
In-house balancing of rotors not only speeds
up the process; it also reduces the cost and the
turnaround time of repairs. The machine is also
available to external customers on a first-come-
first-served request.
Marthinusen & Coutts also performs on site
As the operator of the largest independent high speed dynamic balancing machine
in sub-Saharan Africa, Marthinusen & Coutts, a division of ACTOM, has an in-depth
understanding of the importance of precision-balancing rotating machines.
Marthinusen & Coutts operates the largest
independent high-speed dynamic balancing
machine in sub-Saharan Africa.

Chamberlain says that the balancing is in
line with international best practice with
industry standard balancing certificates
being issued for each completed rotor.
