The production of conveyor rain covers involves multiple processes, including material selection, feeding, roll forming, shearing, curving, adjustment, and packaging.

Rain Cover Installation and Precautions

The structural framework used to secure the conveyor covers consists of connecting angle steel or Z-beams; the length of this framework must match the total installation length of the conveyor covers. The connecting angle steel or Z-beams are to be welded onto the channel steel or smaller angle steel members located on both sides of the conveyor frame. If supporting angle steel is required, these supports must first be welded to the sides of the conveyor frame, after which the connecting angle steel or Z-beams are welded onto the supporting angle steel.

Among the four types of conveyor rain covers, both the fixed covers and the hinged (openable) covers are fabricated from galvanized corrugated steel sheets or color-coated steel sheets. Typically, for every ten cover positions, a configuration of nine fixed covers and one hinged cover is adopted; alternatively, the two types of covers may be arranged in an alternating pattern. During installation, the hinged cover is positioned to overlap the two adjacent fixed covers on its left and right sides, with an overlap length equivalent to one or two corrugation pitches. It is crucial to ensure that the hinged side of the cover is positioned on the non-access side of the conveyor, while the side featuring the latch mechanism is positioned on the access side.

Secure the rain covers to the connecting angle steel or Z-beams using self-tapping screws, ensuring a minimum of four fastening points per cover sheet.

The “break-point” cover is utilized exclusively at the convex curve points (inflection points) of the conveyor, whereas the “belt-misalignment switch” cover is specifically designed to enclose the belt-misalignment switch. Both of these specialized covers are installed so as to overlap the underlying fixed covers.

Additionally, an “inspection-type” rain cover may be installed at intervals—typically every ten cover sheets—to facilitate maintenance procedures and visual inspections.
