摘要： The present invention relates to a locking head for telescoping cylinders of a telescopic boom, which has a plurality of telescopic boom portions, and a housing which comprises at least one bolt-like cylinder locking body, which can be moved in and out of the housing in order to lock the locking head with a telescopic boom portion, and at least one bolt-like telescope locking body, which can be moved in and out of the housing in order to release the telescopic boom portion for a telescoping movement. The locking head has at least one electric actuator which is designed to actuate the at least one cylinder locking body and/or the at least one telescope locking body.
