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.
