A hoisting tube (12) is attached to a suction pad (5) having an inner volume and an edge providing an air-tight closure to a surface of an object during operation. A vacuum source subjects the hoisting tube (12) to a low pressure, and the inner volume of the hoisting tube (12) is connected to the inner volume of the suction pad (5) in such a way that air may flow from one to the other, the vacuum source providing a lifting force when air flowing into the hoisting tube (12) is limited or cut-off. A valve unit (14) includes a separator (15) that in one position reduces an airflow between the inner volumes of the hoisting tube (12) and the suction pad (5) and in at least one open position allows a maximum airflow therebetween. The valve unit (14) includes an actuator (6) for controlling the position of the separator.
