characterized in that it comprises: at least one housing compartment (1) transversely extending between the two supporting frames (2, 3); said at least one housing compartment (1) being provided with at least one housing seat for accommodating said at least one power supply board (7) of said power supply system.

In an aspect, a wear plate for use with a conveyor system is provided. The wear plate has a plate mount, having a fastener retainer having a retention hole extending through the wear plate, and a retainer support being defined by at least one cut in the wear plate adjacent to and at least partially defining the fastener retainer, the retainer support connecting the fastener retainer to a main portion of the wear plate and enabling the fastener support to be depressed relative to a top surface of the wear plate.

Conveyor apparatus, systems and methods are provided. Some embodiments include pivot assemblies for folding a conveyor frame between transport and operational configurations. In some embodiments, one or more frame sections of the conveyor frame are sized to be received in a shipping container.

A conversion bracket for converting a conveyor frame to accommodate a conveyor belt. The bracket includes a base, a plurality of shaft holders extending from a first end of the base and a plurality of wearstrip receptacles extending from a second end of the base. The bracket attaches to a shaft of a conveyor frame by inserting the shaft into the shaft holders. Wearstrips are inserted into the wearstrip receptacles, which are oriented and configured so that the inserted wearstrips rest on the tops of the shaft.

A conveyor idler replacement system in one example with an H-frame (support frame). The system including a base with a first vertical strut extending from the base, a second vertical strut extending substantially vertically from the base; each of the first vertical strut and second vertical strut comprising a first idler frame bracket on a first longitudinal side of the H-frame; a first idler frame extending between the first idler frame bracket on the first vertical strut and the first idler frame bracket on the second vertical strut; at least one idler attached to the first idler frame, the idler configured to rotate, configured to support a conveyor belt. Including a system for lifting the belt and replacing idler frames.

Embodiments of the inventive concept provide an article transfer apparatus and an article transfer method which can temporarily load a container, and which can vary its size according to necessity, so an interference with surrounding structures do not occur while varying the size. The inventive concept provides an article transfer apparatus at which an OHT transfers a container. The article transfer apparatus includes: a top support unit fixed to a top space within a semiconductor fab; a bottom support unit positioned spaced apart below the top support unit and on which the container is mounted; a link unit coupled between the top support unit and the bottom support unit and which can be folded; a folding driving unit connecting the top support unit and the link unit, and configured so when not driven a space that the container can be mounted on is formed by the link unit being spread, and when driven the bottom support unit closely contacts the top support unit by folding the link unit, and wherein the folding driving unit is positioned to not go beyond a top portion of the support unit.

The application relates to a device and to an assembly line for producing a supporting structure for a passenger transport system, such as an escalator, which have a sequential arrangement of semi- or fully automatically operating and mutually cooperating assembly stations and a sequential order of assembly steps. Each of the assembly stations can include at least one holding device and at least a welding robot as well as, optionally, at least one handling robot. The assembly stations are configured in such a way that intermediate products can be produced efficiently by respective assembly steps. Each can be coordinated with a subsequent assembly station, so that the intermediate products can be passed sequentially with optimized short cycle times from assembly station to assembly station, to be able to provide a finished, load-bearing supporting structure at the end of the sequence.
