Channel Stringer Belt Conveyors
Belt conveyors designed with channel stringers are available in 10' and 20' standard sections. Depending on the required belt conveyor length, an additional custom length section will be supplied. A bolted splice plate connection joins and stiffens each joint. Belt conveyor channel stringer sections can be joined to truss sections by special lateral frames for spanning distances that require a truss section, while still enabling channel stringers to be used where the spanned distance does not require a truss. The channel frame belt conveyor design is especially suited to any application where overhead clearance is limited.
Truss Frame Conveyors
Truss frame belt conveyors are available in 24' deep and 42' deep sections. As with the channel frame belt conveyors, a custom-length section may be required to meet customers' required belt conveyor lengths. The truss frame belt conveyors are used in applications where a channel frame conveyor cannot span a distance unsupported.
Slider Bed Belt Conveyors
Heavy, conservative design ensures long life while also minimizing the number of intermediate supports needed for industries using light bulk material densities. Conveyors requiring moderate incline (23 degrees or less) may be supplied with special cleated belts.
U-trough Belt Conveyors
U-trough belt conveyors are used to provide better material containment on the carrying run. They minimize fallback and increase efficiency in inclined applications when used with wood chips to provide more inter-meshing of material.
Flat Slide Belt Conveyors
Flat slide belt conveyors are used when weighing the material is necessary, when the belt serves as a feeder, or when limited overhead clearance requires a flat slide design.
Totally Enclosed Belt Conveyors
Sealed covers and drip pans allow for virtually dust-free material belt conveyance. Corrugated or non-corrugated covers are available. Drip pans are of 14 gauge steel, standard construction.
Custom Engineered Belt Conveyors
If none of the standard belt conveyor designs fit your needs, Orthman will design a custom belt conveyor application for you. By supplying us with specifications and/or drawings illustrating the particular application, we will be able to produce general arrangement drawings for your approval.
Orthman offers several different styles of industrial and food-grade belt cleaners. The standard design is a spring-loaded belt cleaner with either a rubber or UHMW scraper blade. This type of cleaner is the most often used and will provide adequate cleaning in most applications. Motor-driven brush-type cleaners are also available for applications where the scraper-type cleaner does not remove enough material. Please consult with Orthman to determine the type of belt cleaner best suited for your application.
Flanged Inlet Load Hoppers
Load hoppers are available for non-enclosed conveyors. A load hopper guides the incoming flow of material onto the belt and bolts to the top of the belt conveyor structure. If needed, impact idlers or a load section is located under the hopper's discharge point. The chute sides may be inclined or vertical to suit individual applications.
Standard Belt Conveyor Covers
Orthman offers a variety of standard conveyor covers to protect the belt, material and idlers from the weather and other contaminants. Conveyor covers protect the belt from sun damage, in addition to protecting the idler rollers and belt from freezing.
Belt Conveyor Deck Plates
Belt conveyor deck plates are used to prevent material from the carrying run of the belting from falling onto the return run of the belting. Typically, 16 gauge material is used, although thicker material is available if needed. Inclined conveyor decking is designed to shed water and debris, while still protecting the belt and return idlers.
Essential for belt conveyors running in areas where delicate machinery or people may be underneath the conveyors, the fabricated drip pans are designed to keep any material on the carrying (if there are no deck plates) and return runs from falling below the conveyors. For totally enclosed belt conveyors, gaskets will be provided to ensure the drip pans are dust-proof.
