Variable transformer holding device for e-locos

In an electric locomotive including a crossmember, an underframe having a longitudinal member, and a transformer fixed to the underframe during operation, a transformer holding device comprising:

• at least one transformer support configured to displace the transformer on the underframe during a maintenance operation to achieve a predetermined center of gravity position of the electric locomotive;
• said at least one transformer support including:
• at least one holder fastened to the locomotive longitudinal member or the locomotive crossmember, and
• a transformer claw disposed between the transformer and said at least one holder, said transformer claw displaceable relative to said at least one holder in a longitudinal direction and in a transverse direction during the maintenance operation;
• and
• an intermediate element disposed between said at least one holder and said transformer claw, said intermediate element configured to permit said transformer claw to be displaced relative to said at least one holder in the longitudinal and transverse directions during the maintenance operation;
• said intermediate element including a clampable dovetail fixing having at least two dovetail elements displaceable in different directions relative to one another.
