Why Choose CHLC Longitudinal Conveyor Belt Covers?
The Economical Corrugated Cover — The CHLC hood assembly is a ¾ corrugated cover and band with 135° coverage. Because the corrugations run parallel with the belt, the CHLC is a more economical cover system than perpendicular-corrugated designs — corrugated protection at a lower cost.
Open-Side Access, No Lifting — CHLC covers are stationary with a standard 45° opening. The open side lets crews inspect or view the material being conveyed and repair, replace, grease, or inspect the idlers without touching the cover assemblies.
Weather Protection — CHLC covers protect the belt, idlers, and conveyed material from the hot sun, wind, snow, rain, and other damaging weather elements — reducing belt wear and keeping material in spec. Covering a belt also helps operations manage airborne dust in line with OSHA combustible dust guidance.
Galvanized Construction — Standard cover panels are made from 24-gauge, G-90 corrugated galvanized steel, with bands made from 20-gauge, G-90 corrugated galvanized steel. Assemblies come with heavy-duty galvanized steel mounting clip angles and standard zinc-plated hardware. If heavier gauges are required for loading requirements, RPS can meet them.
Sizes & Configuration
Standard CHLC cover assemblies are made for 18″, 20″, 24″, 30″, 36″, 42″, 48″, 54″, 60″, 72″, 84″ and 96″ belt widths — custom sizes are also available. Assemblies accommodate 3′ through 5′ idler spacing, with 4′-0″ as the RPS standard. Because RPS manufactures everything to order, most custom dimensions can be produced for your specific project.
Longitudinal or Perpendicular Corrugations? CHLC vs. CHCS vs. CHCO
All three corrugated series share galvanized G-90 construction — the differences are corrugation direction, coverage, and access. The CHLC runs its corrugations parallel with the belt, making it the economical corrugated option, with 24-gauge cover panels and 20-gauge bands. The CHCS Series runs perpendicular corrugations with 20-gauge covers and bands throughout; both CHLC and CHCS are stationary ¾ covers with 135° coverage and the standard 45° open side for idler access. The CHCO Series steps up to a full 180° corrugated enclosure with hinged, quick-opening access — the pick when maximum coverage and dust containment come first. Prefer smooth steel? See the CH Series (full hinged) or CH75 Series (¾ cover).
Material Options
| Material Option | Typical Applications | Construction |
|---|---|---|
| Galvanized Steel (standard) | Cost-conscious outdoor conveyor protection with open-side idler access. | 24-gauge G-90 corrugated galvanized cover panels, 20-gauge G-90 corrugated galvanized bands; galvanized clip angles, zinc-plated hardware. |
| Aluminum | Weight-sensitive structures and corrosive atmospheres. | Aluminum cover and band material. |
| Stainless Steel | Corrosive environments and maximum service life. | Stainless steel cover and band material. |

What to Send for a Quote
Three numbers get you a fast, accurate quote: your belt width, your idler spacing, and the footage to be covered. Add the site conditions — coastal air, chemical exposure, unusual wind loads — and any color or coating requirements, and our team will confirm material, gauge, and accessories for the application. Because every assembly is fabricated to order, retrofit jobs on existing conveyors are routine: covers are built to your structure, regardless of who made the conveyor.

CHLC Series Frequently Asked Questions
What is a longitudinal conveyor belt cover?
A longitudinal cover runs its corrugations parallel with the belt. The CHLC hood assembly is a ¾ corrugated cover and band with 135° coverage, and the parallel corrugations make it a more economical cover system.
How is the CHLC different from the CHCS series?
Corrugation direction and gauge. The CHLC runs corrugations parallel with the belt, with 24-gauge cover panels and 20-gauge bands, making it the more economical system. The CHCS runs perpendicular corrugations with 20-gauge covers and bands throughout. Both are stationary ¾ covers with 135° coverage and a standard 45° opening for idler access.
What belt widths does the CHLC series fit?
Standard CHLC cover assemblies are made for 18″, 20″, 24″, 30″, 36″, 42″, 48″, 54″, 60″, 72″, 84″ and 96″ belt widths. Custom sizes are available, and heavier gauges can be supplied where loading requirements demand them.
What idler spacing do CHLC covers accommodate?
Assemblies are made to accommodate 3′ through 5′ idler spacing, with 4′-0″ as the RPS standard.
What material options are available?
Standard cover panels are 24-gauge, G-90 corrugated galvanized steel with 20-gauge, G-90 corrugated galvanized bands, heavy-duty galvanized mounting clip angles, and zinc-plated hardware. Optional cover and band materials include aluminum and stainless steel.
Are CHLC covers BABA compliant?
Yes — RPS conveyor covers are fabricated at our Elgin, Illinois facility and are BABA compliant for federally funded projects. Material sourcing can change, so contact RPS directly to confirm current sourcing for your order.
