Abstract (en)

[origin: EP3550075A1] Paving screed (7) for a road paver (1), comprising an upper frame (14), a lower frame (15) mounted on the upper frame (14) in a height-adjustable manner, a linear actuator configured to adjust the lower frame (15) vis-à-vis the upper frame (14) in a vertical direction, a height-adjustment drive (16) configured to drive the linear actuator, and a locking device (23) configured to immobilize the lower frame (15) in its position relative to the upper frame (14), wherein the locking device (23) is connected to the upper frame (14) and the lower frame (15) and comprises an essentially vertically oriented hydraulic cylinder (20) configured to exert a clamping force at least partially parallel to the direction of adjustment of the linear actuator on the latter so that a frictional connection is created in the linear actuator, which prevents an adjustment of the linear actuator.
