Abstract (en)

[origin: WO9940015A1] The invention relates to a builder's hoist, comprising a hoist mast which can be fixed in an upright position and a hoist cab which travels up and down the hoist mast and which has at least one motor drive unit with controls. The aim of the invention is to further develop a builder's hoist of this type to provide as simple a means as possible of ensuring that no people or objects are situated beneath the hoist cab when the hoist is travelling downwards. To this end, the builder's hoist (1) is equipped with an optical surveillance device (5) which surveys the space above the hoist platform (2) and which is connected to the controls of the motor drive unit (7) in such a way that it is possible to stop the motor drive unit (7) at least when the hoist cab (4) is travelling downwards if the space above the hoist platform (2) is not clear.
