Application of hydraulic press for testing powered roof prop supports

摘要

The report presents the possibility of using press forging, used in a smelter in the crushing and forming steel ingots processes, to the operation of compression powered roof supports. Press have been redeveloped which is to construct, to produce and to exchange handles so that they can be mounted in these housing racks in an upright position. Given the capability of measured quantities, measurement procedure and methodology of the study. There were presented some exemplary results of the tests.
