The invention discloses a lifting mechanism (1) of a crane, comprising: at least one rope drum (2) for lifting a rope (3); at least one lifting motor (4, 5) for driving the rope drum (2); a gear arrangement (6) coupled between the rope drum (2) and the lifting motor (4, 5) and having an input gear (7, 8) on the lifting motor (4, 5) side and an output gear (9) on the rope drum (2) side; and brakes (10, 11) for braking the input gears (7, 8). The gear device (6) has a differential (6a) which is provided with a first input gear (7) and a second input gear (8), the first input gear (7) and the second input gear (8) being coupled to each other and also to the output gear (9). Wherein a first lifting motor (4) connected to the first input gear (7) and a second lifting motor (5) connected to the second input gear (8) are arranged, and wherein the first input gear (7) and the second input gear (8) have an unequal total gear ratio with respect to the output shaft. The invention also relates to a method for operating the lifting mechanism.

    本发明公开了一种起重机的提升机构(1),该提升机构包括:用于提升绳索(3)的至少一个绳索卷筒(2);用于驱动该绳索卷筒(2)的至少一个提升电动机(4,5);齿轮装置(6),该齿轮装置联接在该绳索卷筒(2)与该提升电动机(4,5)之间,并且具有在该提升电动机(4,5)侧的输入齿轮(7,8)以及在该绳索卷筒(2)侧的输出齿轮(9);和用于制动该输入齿轮(7,8)的制动器(10,11)。该齿轮装置(6)具有差速器(6a),该差速器布置有第一输入齿轮(7)和第二输入齿轮(8),其中该第一输入齿轮(7)和该第二输入齿轮(8)彼此联接并且还联接到该输出齿轮(9),其中布置了连接到该第一输入齿轮(7)的第一提升电动机(4)和连接到该第二输入齿轮(8)的第二提升电动机(5),并且其中该第一输入齿轮(7)和该第二输入齿轮(8)相对于输出轴具有不相等的总齿轮齿数比。本发明还涉及一种用于操作该提升机构的方法。
