When Terex® MPS needed a reliable and flexible system to measure stress on its range of stone crushing machines, it turned to HBM – a market leader in the field of test and measurement – to provide a comprehensive and effective solution.

Jaw Crusher and issues faced

As part of its ongoing research towards the development of this powerful and reliable range, HBM was asked to consult on the LJ5139, which will be the largest tracked mobile machine in its range when fully developed.

The issues being faced by the LJ5139 Jaw Crusher, which was tracked and being used in a quarry, were varying in nature. With the machine itself weighing up to 110 tonnes, the chassis is subject to high loads when tracking across the quarry on uneven surfaces. In addition, the hopper and feeder receives high impact forces when large stones, often up to 1 cubic m are dropped from the excavator which is used to feed it; this opens up the risk of damaging the part. Moreover, the crusher itself is subject to forces of up to 8000kN during the crushing process.

HMB’s solutions

After a thorough study of the issues faced, HBM specified its rugged DAQ, SomatXR series, which is particularly suitable for use in harsh environments.  To compliment this package, HBM also suggested the Somat MX1615B-R module and related accessories, which included RF-9 strain gauge rosettes.

The powerful SomatXR data acquisition system is specially developed for use in harsh environments. The modules provide a wide temperature range and are protected from humidity, dust, shock and vibration.

The data acquisition system provides a web interface for simple operation without any software installation. This allows for convenient channel parameterization, monitoring of measurement jobs and visualization of measured data far away from the measuring point.  This was a particularly significant feature for Terex® MPS given the nature of the measurement task.

The outcome

HBM data acquisition systems are suitable for a wide range of mobile testing applications but the immense load requirements and extreme environmental conditions surrounding Terex® MPS did present a challenge.  However, thanks to HBMs extensive experience in mobile testing and demanding fields, it was able to provide a solution which offers Terex® MPS the flexibility of being able to work around available and convenient testing windows.  In turn, the equipment has enabled them to mount equipment and leave it running over the course of a few days to achieve gathered data, which has proved to be an invaluable asset.
