The invention relates to a lifting device (17) for controllably lifting a payload (23) in an elevator shaft (3), the invention relates to a lifting device for an elevator shaft (3), comprising a platform (19) which can be fixed in the elevator shaft (3), a holding device (33) which can be fixed to a payload (23), a lifting rope (29) which is mounted on the holding device (33), for example a safety rope (31) which is mounted on the holding device (33), a traction device (25) which is fastened to the platform (19), and an anti-fall device (27) which is fastened to the platform (19), for example. The traction device (25) is designed to actively and controllably displace the lifting rope (29) relative to the platform (19). The lifting device (17) is arranged in such a way that the safety rope (31) is displaced in such a way as to maintain the safety rope in tension during a relative movement between the holding device (33) and the platform (19). The safety rope (31) and the anti-drop device (27) are designed in such a way that the anti-drop device (27) prevents a further relative movement between the safety rope (31) and the anti-drop device (27) in the event of a malfunction of the lifting rope (25).
介绍了一种用于在电梯竖井(3)内能够受控地提升有效载荷(23)的提升设备(17),所述提升设备具有能够固定在电梯竖井(3)中的平台(19)、能够固定在有效载荷(23)上的保持装置(33)、安装在保持装置(33)上的提升绳索(29)、例如安装在保持装置(33)上的保险绳索(31)、紧固在平台(19)上的牵引装置(25),以及例如紧固在平台(19)上的防坠装置(27)。牵引装置(25)被设计成,使提升绳索(29)相对于平台(19)主动且能够受控地移位。提升设备(17)设置成,使得保险绳索(31)当在保持装置(33)和平台(19)之间发生相对运动期间以保持所述保险绳索张紧的方式移位。保险绳索(31)和防坠装置(27)被设计为,使得防坠装置(27)在提升绳索(25)发生故障时阻止保险绳索(31)和防坠装置(27)之间发生进一步的相对运动。
