Good installation and alignment of rotating machinery
is crucial to achieve an optimum performance with
minimal costs. Misalignment will cause problems such as
vibration, bearing and coupling failure and mechanical
wear to different parts. A perfect alignment of your
rotating equipment will result in maximum installation
effi ciency, low maintenance frequency and costs, less
energy consumption and reduction of vibrations and
wear.
For the shipbuilding industry we can also perform
the alignment of propeller shaft and gearbox, the
alignment of bearing journals in relation to stern tube,
measure the fl atness of a slewing ring bearing and
many more.

VIBRATION MEASUREMENTS
SOME VERY COMMON PROBLEMS THAT WE CAN DETECT USING OUR VIBRATION MEASUREMENT SYSTEM: Misalignments Disparity / Offset Damage to machine bearings Worn parts such as gears, belts, etc. Poor lubrication Overloading Clutch design Corrosion and cracks Resonance problems
VIBRATION MEASUREMENTS With our machinery vibration measurement service we
are able to provide a reliable indication of the condition
of rotating machinery, while in operation.
Vibration measurement data will help to detect problems
that might be developing. By monitoring the condition
of machinery, most developing problems can be detected
even before they arise. Detecting defects in such an early
stage will prevent further damage and minimize machine
downtime. The required repair will be simpler, faster, and
cheaper.
Since almost any error or divergence in the machine
sources a different level of abnormal vibration, our
specialists are able to translate the measurement data to
determine the actual, specifi c problem in a machine.
Furthermore, our measurement data can also be used
to prevent unnecessary maintenance, fi nd causes of
production quality problems, stop discomfort and even
avoid a bad company image.
Vibration data taken on a particular physical point and
collected regularly over a period of time (Trending)
supports us to build-up a history of the installation and
it’s waveform characteristics so changes can be detected,
accurate physical explanations can be assigned and
corrective actions taken accordingly.
CHOCKFASTEPOXY PRODUCTS
Specialized maritime epoxy compounds. With Chockfast epoxy products, reliability is guaranteed on all
types of vessels, offshore platforms, mooring buoys, oceanographic
equipment, crane rails and other marine applications.

MECHANICAL CHOCKS
EMHA Technisch Bureau delivers adjustable, self-levelling and reusable mounting chocks that can be used to mount rotating equipment. These mechanical chocks are a blend of cutting edge engineering and years of experience to produce a strong, stiff and elegant device to end machinery soft-foot.
Our mechanical chocks are manufactured with a special thread type
called buttress thread. Unlike common thread types used in mechanical
engineering, buttress thread has an a-symmetric design which comprises a
7° top angle and a 45° supporting flank. As a result of this thread design,
the chocks are more mechanically stiff and have higher load bearing
capacity compared to standard chocks with metric thread of similar
diameter and pitch which uses a 2x30° angle design.
With years of experience in installation and foundation of machinery,
EMHA Technisch Bureau is able to perfectly mount your machines on
our chocks. However, if you like the mounting to be performed by own
personnel, we can also advice and deliver the chocks only.
