Claims10
A support winch configured to provide height adjustment for a vehicle, comprising:
- a steep thread drive;
- wherein the steep thread drive comprises a spindle having a thread;
- wherein a pitch of the thread is configured for height adjustment at a first rate;
- wherein the support winch comprises at least one locking mechanism configured to prevent an undesired height adjustment of the support winch by preventing a rotation of the spindle;
- wherein a first locking mechanism comprises at least one spindle-side engagement region that may be brought into at least one of a form-fitting and a force-fitting engagement with a corresponding stationary engagement region such that the rotation of the spindle is prevented;
- and
- wherein the spindle is mounted such that the spindle is movable along the longitudinal axis, thereby allowing for an engagement and disengagement between the spindle-side engagement region and the corresponding stationary engagement region.
