Container Cranes

Condition monitoring on container cranes is complicated. To obtain reliable readings, consistency is of the essence. Measurements need to be carried out at very specific moments in time, when conditions for load, rpm, rotational direction and trolley traveling direction etc. are met.

Typically, the True Shock Pulse Method® and SPM Spectrum™ is used for condition measurement and analysis of the gear box and crane motor bearings, usually in combination with vibration measurements.

The True Shock Pulse Method examines the mechanical state and lubrication condition of rolling element bearings, detecting problems such as installation faults and poor lubrication. SPM Spectrum™ uses FFT analysis to efficiently verify shock sources, such as bearings, damaged gears or disturbance.

Wind Turbines

Wind turbines are particularly exposed when it comes to vibration and disturbances. Variable operating conditions, such as wind velocity, power generation, rpm, temperature etc. affect measuring results as well as condition evaluation. This requires the possibility to adjust alarm levels to the current situation. Intellinova® handles such fluctuations with great precision. A typical wind turbine setup involves shock pulse measurement with SPM Spectrum™ on gearboxes and on generator and main shaft bearings, combined with vibration measurement with EVAM on e.g.  gearboxes to detect misalignment, unbalance, loose parts and other common vibration symptoms.

Vibration is measured according to ISO standards and detects common machine faults like imbalance, structural weakness and loose parts. With access to machine specific data and information on the vibration behaviour of the machine under normal operating condition, EVAM (Evaluated Vibration Analysis Method) is an elaborate analysis tool for verifying the root cause of vibration problems.
