This is true, but actually it is the least interesting aspect of the weighing topic.\u00a0<strong>The most interesting purpose and the most difficult to evaluate as well is to weigh in order to\u00a0check\u00a0the set-up of the rolling stock on track<\/strong>. For this reason, we talk about measuring the\u00a0<strong>vertical forces &#8220;Q&#8221;\u00a0<\/strong>of each wheel on track.<!--more--><\/p>\n<p>During the life cycle of any rail vehicle, without considering the weight changes, the distribution of the wheel forces is mainly a function of the wear of the wheel rolling surfaces diameters and of the suspensions stiffness.<\/p>\n<p>So, especially for mantained vehicles with worn wheels,\u00a0<strong>measuring on the wheel tyre near the wheel reference point<\/strong>, instead of other points as the wheel flange or the axle box, is\u00a0<strong>fundamental\u00a0<\/strong>to correctly understand the real rolling stock balance on the track. Obtaining the best wheel force distribution allows to\u00a0<strong>improve the running safety and to extend the life cycle<\/strong>\u00a0of the wheels and the rails, because it minimizes potential slips during traction and braking.\u00a0<strong>POWERVE\u00a0<\/strong>is a hand-portable system, able to perfectly measure the vertical forces loaded from each wheel of a railway vehicle on the rail.<\/p>\n<p>It measures on a straight track and the load cells are interposed just between the top of the rail and the wheel tyre at the wheel\/rail interface, not on the wheel flange.\u00a0<strong>POWERVE measures the true rolling stock balance on the track, preventing derailments.<\/strong><\/p>\n<p style=\"text-align: center;\"><strong>What is your experience in weighing a rolling stock?
