Abstract (en)
[origin: WO2007094720A1] The invention relates to a vacuum hoisting device with a vertical hoisting tube (2) suspended at its upper end and connected to a vacuum source (4), and which at a lower end is provided with a suction foot (14) and a tubular positioning handle (15) for manoeuvring of the suction foot, and a manually operated valve device (26), which is kept closed for hoisting of the suction foot and is kept open for lowering of the suction foot by admission of air to the hoisting tube. For operating the valve device (26) this is connected with a grip sleeve (16) slidably journalled on the positioning handle, which is directed obliquely downwards, and the connection of the valve device (26) to the grip sleeve (16) is designed such, that the valve device closes when the grip sleeve is slided upwards and opens when the grip sleeve is slided downwards for synchronizing the movement of the suction foot upwards and downwards with the movement of the grip sleeve.
