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.

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.
