Abstract

The invention relates to a trolley for a lifting device, comprising lifting gear (1) arranged on a support frame (5) and comprising wheels (3a, 3b, 3c, 3d) which are mounted on the support frame (5), via which the trolley (1) can be moved on a support (2), and at least one first wheel (3a) of which is mounted on an axle. The axle can be driven together with the wheel (3a) by means of a drive motor (4). The aim of the invention is to provide a trolley which ensures a reliable transmission of drive forces between the wheels and the rail. According to the invention, this is achieved in that the drivable first wheel (3a) is connected to at least one of the other wheels (3b, 3c, 3d) in a driving manner via a flexible drive (10) such that the axle is arranged between the drive motor (4) and the flexible drive (10) and thus the flexible drive (10) is connected downstream of the axle in a driving manner so that the flexible drive (10) can be driven by the axle.

Abstract

The invention relates to an arrangement consisting of a travelling gear carrier (5) and a running wheel block (6) fastened detachably thereto, wherein the running wheel block (6) consists of a housing (7) with at least one connection surface (8) and a running wheel (11) which is mounted in the housing (7) and protrudes out of the housing (7), and the running wheel block (6) is aligned with respect to the travelling gear carrier (5). In order to facilitate the exchange of running wheel blocks, it is proposed that an undertaken alignment of the running wheel block (6) with respect to the travelling gear carrier (5) is secured in such a manner that a machined groove (10), in which a machined plate (14) is held in a form-fitting manner, is arranged on the connection surface (8) of the running wheel block (6) and, after the running wheel block (6) has been aligned with respect to the travelling gear carrier (5), the plate (14) is fixedly connected to the travelling gear carrier (5). The invention also relates to a method for the installation of an arrangement consisting of a travelling gear carrier (5) and a running wheel block (6).

Abstract

The invention relates to an arrangement of a suspension (34) and of a rail (2), in particular for suspending a travel and/or carrier rail of a suspension track, a suspended conveyor, or a lifting gear on a chassis or frame, having a tension element (44, 52) supporting the rail (2) at one end thereof in the region of a profile head (22) by means of a mounting element (38), said head being substantially C-shaped in cross section, and forming a gap (24) running at the top along a longitudinal center plane (L) of the rail (2). In order to produce the arrangement, combining simple assembly with a high level of security and high load-bearing capacity, while simultaneously allowing free and retroactive positioning on the rail without disassembling the rail, the mounting element (38) comprises a pivotable part (35, 51) that can be pivoted with respect to the tension element (44, 52), the profile head (22) and the pivotable part (35, 51) being designed such that the pivotable part (35, 51) can be guided through the gap (24) from outside into the profile head (22) in a loading position, and can be pivoted into a mounting position in which the pivotable part 35, 51) contacts the profile head (22) from the inside, bridging the gap (24).

Abstract

The invention relates to an arrangement of two rail segments (2aa, 2ab; 2ba, 2bb), consisting of at least one mounting element (7) disposed at each rail segment (2aa, 2ab; 2ba, 2bb), and of at least one connector in contact with the mounting elements (7), by means of which the rail segments (2aa, 2ab; 2ba, 2bb) can be connected to each other at the end faces thereof, wherein each mounting element (7) is attached to the corresponding rail segment (2aa, 2ab; 2ba, 2bb) by means of a welding seam (12). In order to produce an improved arrangement for connecting rail segments with respect to dynamic loading, at least one end (13) of the welding seam (12) ends in a region on the rail segment (2aa, 2ab; 2ba, 2bb) outside of the mounting element (7).

Abstract

The invention relates to an arrangement of a rail (2) for suspended conveyors or suspended cranes and a slip contact holder (39) mounted thereon, wherein the rail (2) comprises a profile body (23) and a profile head (22) connected thereto and disposed above the profile body (23), wherein the profile body (23) is C-shaped in cross section, forms a hollow space for chassis, and has a slit (31) open to the bottom, and the profile head (22) comprises upper, substantially horizontal profile walls (29a, 29b) and the slip contact holder (39) is disposed within the hollow space (H) and attached to the upper profile walls (29a, 29b). In order to produce an arrangement providing simple and secure attachment of the slip contact, the invention proposes that a plurality of punchouts (41) are disposed in the upper profile walls (29a, 29b), disposed in at least one row and at regular, repeated distances as seen in the longitudinal direction of the rail (2), and barb-like catch pawls (42) are disposed on the slip contact holder (39) and engage with the punchouts (41) in order to attach thereto.

Abstract

The invention relates to an arrangement for connecting two successive contact line rails, each made of a longitudinal plastic profile and of at least one contact rail extending along the contact line rails, having a contact rail connector connected to the opposing ends of the contact rails of two successive contact line rails, electrically and mechanically connecting the contact rail ends of the contact rails, and having additional elements attached at the opposing rail ends of the contact line rails of two successive contact line rails, covering the contact rail connectors and displaceable relative to the intermediate element in the longitudinal axis thereof. In order to provide an arrangement for compound two successive contact line rails that is simple to produce and allows uncomplicated assembly, the invention proposes that an intermediate element (8a, 8b) is attached at each of the opposing rail ends (7a, 7b) of the contact line rails (1a, 1b) to be connected and the additional elements (11a, 11b) are attached to the intermediate elements (8a, 8b).V
