  • Messung erfolgt auf der Spurkranzkuppe, wodurch keine Querkräfte, die das Messergebnis beeinflussen können, auftreten 
  • Keine Beeinflussung der Messwerte durch Querversatz der Räder

The ELAS-m mobile corner force measuring unit was developed in response to market demands for lower-cost alternatives to automatic stress test rigs.

The compact design of the system makes it suitable for mobile use on jacks at different locations. This provides a high degree of certitude for those with responsibility for planning and budget.

The integrated precision lift facility allows exact positioning in respect of heights and forces. The special design of the measuring points guarantees that heights will be sustained and forces held, even for relatively long periods of time. This prolonged height hold is essential if a geometric measurement of the profile of the coach body is required after the position or reference position of low torsional stress has been reached.

The portable high-precision 4-point measuring system, ELAS-m, can easily be integrated into jack stands, or in the case of ELAS-h, into lifting jack systems. The integrated precision lift facility enables precise control of heights and forces, which is crucial for measuring low-torsion positions of coach bodies or determining the center of gravity. The integrated ELAS-data software supports the measuring process by continuously monitoring and comparing the measured and calculated corner forces. This software-assisted control significantly reduces operational errors. A visual notification is displayed to the user as soon as the desired low-torsion position is reached. This functionality makes the system particularly reliable and efficient in use, especially for critical tasks such as the geometric measurement of coach bodies.

The ELAS system was developed to meet market demands for cost-efficient alternatives to automatic test rigs. Additionally, the system features patented pendulum heads and plain bearings that ensure neutral force transmission and compensate for mechanical stresses in the vehicle, guaranteeing highly accurate and reproducible measurement results.

The modular design of the system allows for quick replacement of defective components, minimizing downtime and ensuring smooth operation of the measurement process. The system is delivered pre-calibrated, eliminating the need for time-consuming adjustments or on-site setup. Calibration, according to DIN 7500-1, is performed by an independent, accredited body, which is certified according to DIN EN ISO/IEC 17025.

The system can be delivered as either a semi-automatic or fully automatic unit and allows for the convenient adjustment of the low-torsion position of the coach body through an advanced control concept, while the lifting or tilting of the coach body is achieved via lifting spindles. The innovative ELAS-data control software enables automatic data acquisition, evaluation, and control. The system is equipped with a precise height measurement system, patented pendulum heads, and plain bearings that ensure accurate measurement results even with slight inclinations.  

A version as a movable system on rails, known as rolling supports, is also available, as is a relocatable system on jack stands. A unique feature is the integrated support sleeve, which serves as fall protection for the coach body while also protecting the measuring head when retracted.  

Calibration is carried out by an independent accredited body in accordance with DIN 7500-1. This body is further accredited by the German Accreditation Body (DAkkS) in accordance with DIN EN ISO/IEC 17025.
