摘要： A large manipulator includes an articulated boom that can be folded out. The articulated boom includes boom segments including a last boom segment having a boom tip. The articulated boom includes an end hose and end-hose holder. The end hose is flexible, arranged on the last boom segment, and can be removably coupled to the last boom segment by the end-hose holder. The end-hose holder includes a holding bracket arranged on the last boom segment. The holding bracket is configured to be pivotable into a first pivot position, a second pivot position, and a third pivot position relative to the last boom segment.

摘要： A hydraulic rotary drive includes a first rotary drive element and at least two annular pistons connected to the first rotary drive element in a rotationally fixed manner and configured to be axially movable on the first rotary drive element between two end positions. Each annular piston has two annular spur serrations directed away from one another. The hydraulic rotary drive includes a second rotary drive element with ring type serrations that are complementary to the spur serrations of the annular pistons. The hydraulic rotary drive includes a control unit that is configured to control supply of hydraulic fluid to the annular pistons to cause a reciprocating movement of the annular pistons on a shaft in accordance with an operating signal. The hydraulic rotary drive includes a sensor arrangement communicatively coupled to the control unit and arranged to detect the positions of the annular pistons along respective sliding paths.
