Description

The present invention relates to a device for lifting and transferring a railway vehicle off a railway track, and a method for lifting and transferring it.

It is sometimes necessary to be able to move a railway vehicle out of its main track to carry out repair or maintenance operations. Methods are known for lifting and transferring a railway vehicle out of a railway line using a crane or a lift.

However, such methods are not entirely satisfactory.

Indeed, the use of a crane requires large spaces and complex operations to be set up, and the lift only allows the lifting of the rail vehicle.
