Testing the stability of cranes and construction machinery PDF Print

Testing the stability of mobile cranes, earth-moving machinery, lift trucks and other devices are performed in order to determine maximum parameters of machine operation and at the same time assuring its safety against turnover.

Testing makes it possible to check the calculations of stability performed in a process of machine constructing.

During the tests we can define:

  • curves of limit lifting capacities,
  • curves of permissible lifting capacities according to appropriate standards,
  • position of the horizontal centre of gravity in different positions of working equipment

As part of verification of permissible loads, selected points of characteristic of machine lifting capacity are checked relative to overload defined in standards.


The tests are performed according to procedures and methodologies elaborated in the Institute and with modern apparatus as well as the sensors by Hottinger (Germany). The processing of results of measurements is made by means of special software.
