The quality of press conjunction of railway wheels is estimated using diagram of pressing-in, that is why the press has a device for recording diagram “pressure-space”.

The press is equipped with controller, which allows programming the main technological parameters, authorizing users, saving in memory all relevant operator’s actions, etc.


Example 1. Press Muscle KPRZ-630М.04 with loading carriages and centering cylinders. The press is recommended for pressing-out and pressing-in of wheelsets with increased requirements for alignment (for example, wheel sets of Siemens trains).
















The press is equipped with both power rods and 4 guide columns, which allow accurate centering of the equipment when pressing-in and pressing-out. Centering cylinders on the back traverse and on the power cylinder make it possible to position the wheel set exactly on the axis and perpendicular to the thrust traverse of the press.
