The invention relates to a lifting device, especially a lift or a lifting platform, comprising a displacement unit (1, 6, 7, 8) for at least partially displacing a load in a vertical manner. The displacement device (1, 6, 7, 8) comprises at least one first drive motor (1) comprising a first motor shaft (3) and especially a second drive motor (1) comprising a second drive shaft (3), in addition to one first brake unit (2) arranged on a first brake shaft (3) and a second brake unit (2) arranged on a second brake shaft (3), in addition to at least one first drive element (7) which can be rotated about a first drive shaft (6) in order to drive at least one first traction element (8) which is subject to tension and a second drive element (7) which can be rotated about a second drive shaft (6) in order to drive at least one second traction element (8) which is subjected to the effect of tension. The traction element (8) and the load are respectively arranged between at least two drive shafts (6) enabling costs to be reduced and operational safety to be increased in relation to lifting devices of prior art. This is achieved by virtue of the fact that means for the production of a continuous mechanical positive locking are provided, whereby the positive lock comprises at least the first and second brake unit (2) and the first and second drive element (7). |
