Abstract
The disclosure relates to a work machine, comprising a primary energy source for feeding electric energy into a link, a gear for performing a task of the work machine, at least one electric drive connected to the link in order to operate the gear of the work machine, a holding brake for fixing or releasing the gear, and an energy store which is connected to the link in order to provide electric energy demanded from the link upon actuation of a gear and/or to absorb electric energy fed into the link. According to the disclosure, during an emergency lowering of the gear, the at least one electric drive to convert the kinetic energy into electric energy and to feed it into the link. In the event of an unavailability or failure, the primary energy source is configured to absorb the energy fed into the link by the electric drive.

Work machine, comprising:
- a primary energy source for feeding electric energy into a link,
- a gear for performing a task of the work machine,
- at least one electric drive connected to the link to operate the gear of the work machine,
- a holding brake for fixing or releasing the gear, and
- an energy store connected to the link to provide electric energy demanded from the link upon actuation of the gear and/or to absorb electric energy fed into the link,
- wherein
- in the event of an emergency lowering of the gear, the at least one electric drive is configured to convert kinetic energy that is produced into electric energy and to feed the electric energy into the link, wherein
- in the event of an unavailability or failure of the energy store prevailing simultaneously with the emergency lowering, the primary energy source is configured to absorb the energy fed into the link by the electric drive.
