Abstract

An emergency-operation valve block includes: a drive port for hydraulically connecting the valve block to an emergency drive of a mobile crane, at least two drive mechanism ports for hydraulically connecting the valve block to one drive mechanism of the mobile crane each, at least two closing valves which are assigned to one of the drive mechanism ports each and designed to selectively open or close a hydraulic connection between the drive port and the drive mechanism port respectively assigned to it, and an actuation valve which is designed to selectively reverse the hydraulic connection between a pressure side and return side of the drive port and corresponding sides of the drive mechanism ports. A mobile crane may include such an emergency-operation valve block.
