PRESSING PORTALS FOR RAILWAY BOGIES are machines composed by a gantry bridge on which are housed two hydraulic pressers with a thrust of 200 kN each one. The lower part is connected to rails that allows the moving of the bogie and is equipped with bogie positioning devices. The function of the portal is to reproduce in the workshop, by means of the thrust of the pressers, the position and the stresses of the under-chassis in driving conditions and allows the disassembly, assembly and testing of the railway bogies.
The pressers and the positioning devices can be transferred in suitable positions for each bogie, the position of each element is displayed on a monitor. For railway trucks equipped with oscillating girder with fifth wheel couplings very small, the portal allows to work with a single presser transferred to the center. To ensure the passage of locomotives or whole carriages the pressing portal can be realized with two movable girders.
