Abstract
A lifting gear has a load chain sprocket and a drive shaft. The drive shaft drives the load chain sprocket. The lifting gear has a motor having a motor shaft. The motor shaft and the drive shaft are coupled by a brake clutch system. The brake clutch system includes a clutch part and a brake hub on a brake thread of the drive shaft. The clutch part has dogs and the brake hub has pegs. A vane disk is between the clutch part and the brake hub. The vane disk has vane bodies on a coupling portion of the drive shaft. A pressure plate is positioned in a rotationally fixed manner on the drive shaft. Two friction disks are between the brake hub and the pressure plate, and a brake disk is between the two friction disks, and the brake disk is mounted in a rotationally fixed manner.
