摘要:
The invention relates to an escalator (1) or moving walkway, which has a supporting structure (5) and sheet material that can be seen from below (11, 12, 13, 14, 15) delimited in the two-dimensional extent thereof by lateral edge regions. A first lateral edge region (11.1, 12.1, 13.1, 14.1, 15.1) of the sheet material that can be seen from below (11, 12, 13, 14, 15) is firmly connected to the supporting structure (5, 35, 45). Furthermore, the sheet material that can be seen from below (11, 12, 13, 14, 15) is preloaded with a predefined preloading force between the first lateral edge region (11.1, 12.1, 13.1, 14.1, 15.1) and a second lateral edge region (11.2, 12.2 13.2, 14.2, 15.2, 15.3) opposite the first lateral edge region (11.1, 12.1, 13.1, 14.1, 15.11). In order to obtain the preload, the second lateral edge region (11.2, 12.2, 13.2, 14.2, 15.2, 15.3) is firmly connected to the supporting structure (5, 35, 45), wherein, as a result of obtaining the preloading force, the rigidity of the supporting structure (5) is increased and, during operation of the escalator (1) or the moving walkway, noise is reduced.

The invention relates to a gantry device (10) for use in the assembly or maintenance of heavy parts or machine components or metal parts of a travelling device. The gantry device (10) comprises two lateral bipods (11), every bipod (11) having beam-type, elongate limbs (12) and a connecting element (13) and the limbs (12) being secured to said connecting element (13) with their top ends. The limbs have four extension elements (14), an extension element (14) being arranged on a lower end of every limb (12) or support (12) or beam (12). A cross member (15) extends between the two lateral bipods (11) and is secured to every end of the cross member (15) in the corresponding connecting element (13). The device (10) further comprises a trolley with a roller, which trolley is arranged on the cross member (15) in such a manner that it can be displaced along the cross member (15) in the area between the lateral bipods (11) or horizontally moved.

The invention relates to a handrail drive 2 for driving a handrail 3 of a conveying system, said handrail drive 2 having at least one drive device 4 and at least one counterpressure device 5. The counterpressure device 5 comprises at least one clamping spring 42 and at least one counterpressure roller 32 to 39. The handrail 3 is arranged between the drive device 4 and the at least one counterpressure roller 32 to 39 approximately in a linear direction of travel 29, 30 and is urged by the at least one counterpressure roller 32 to 39 against the drive device 4 by a contact pressure force 45 caused by the clamping spring 42. The handrail drive 2 has a mechanical deflecting device 80 by means of which the spring force 44 of the clamping spring 42 can be deflected into the contact pressure force 45 of the at least one counterpressure roller 32 to 39.
