Remcon can build multiple different styles of conveyors, depending on what would work best for each application. Below you will find a list of the different types of conveyors Remcon offers and a brief description of each type, with links to specific pages for each type of conveyor. Please don't hesitate to contact us if you have any questions or need help deciding which type of conveyor might work for your application.
Chain / Chain Belt Conveyors
|
Chain conveyors use heavy chain mounted to both sides of a belt to pull the belt around the conveyor. The belt is supported laterally by steel cross members bolted to the underside of the belt and attached to the chain. This includes drag chain, roller chain, combo rubber/pvc roller chain belts, and steel pan roller chain belt conveyors.

Heavy-Duty Roller Conveyors
Slider Bed Conveyors
|
Slider bed conveyors employ a rubber or PVC belt which is driven around the conveyor by the friction of the belt on the drive pulley. The belt slides on steel slats, instead of idler rollers, making for fewer moving parts to wear out and replace. Remcon's simple but versatile slider bed conveyor design often allows this type of conveyor to be used in place of other more complicated or more expensive types of conveyors.

Highlights & Benefits of Remcon Conveyors
Below are some of the special features that apply to most, if not all Remcon conveyors. Many more special features pertaining to each specific conveyor or conveyor type can be found the page for each type of conveyor.
CLEAT OPTIONS
Conveyors, (as well as pulley diameters) are designed to accept various cleat designs, such as chevron or regular style cleats, up to 2” high (or even taller, on some conveyors). If it is decided to add cleats after the conveyors are installed, heavy-duty rubber bolt-on cleats may be added easily without modifying the conveyor.
COMMON COMPONENTS
Remcon conveyors are all built from components widely distributed throughout the USA, providing quick and easy service if needed from just about anywhere in the country.
CONVEYOR ALIGNMENT
Remcon conveyors are shop fabricated in the longest sections practical (up to 40 ft.). Adjoining sections are aligned accurately with each other in the shop as they are fabricated. The entire conveyor is aligned again (and leveled) during installation, to prevent the belt from wandering and wearing into the side of the conveyor.
SELF-CLEANING RETURN PANS
Remcon conveyors are designed with pans to support the return belt instead of idler rolls. This design has been used by Remcon successfully since 1978.
The return belt pans offer several advantages:
DRIVE METHOD – Parallel gear, shaft mounted, torque arm reducers (Dodge Torque Arm II)
Remcon's preferred conveyor drive method uses a Dodge Torque Arm II reducer driven via separate motor, v-belts and sheaves. These reducers have been used almost exclusively in sand, rock, gravel, mining, etc., industries, for many years, and are well proven. Remcon has used them since 1990, with good success. The new generation has been engineered throughout with features designed to improve performance, extend service life, and reduce maintenance. Remcon's normal configuration of these reducers being driven by a separate motor by v-belts using different combinations of sheave allows for additional speed reduction.
The advantages of using the Dodge Torque Arm II, shaft mount reducer with v-belt drive are as follows:

SELF-CLEANING RETURN PANS
Remcon conveyors are designed with pans to support the return belt instead of idler rolls. This design has been used by Remcon successfully since 1978.
The return belt pans offer several advantages:
- Reduced maintenance – The need for idler rollers and the maintenance that they require (greasing, tracking, cleaning) is eliminated, because the return belt and cleats slide in the smooth, one-piece return pan.
- Safety – The return belt and cleats are completely guarded by the return pan. Because the pan is an integral part of the conveyor, a serious safety problem is eliminated. There are no pans that must be removed for cleaning. This eliminates the possibility of workers failing to close or re-install the pans, which would expose dangerous pinch points. It also eliminates the problem of removing pans that have become filled with a heavy load of debris.
- Cleanliness – All carryover from the head pulley, plus any debris that falls off anywhere along the return belt is captured in the return pan and dragged to clean-out openings along the length of the conveyor or a collection area at the in-feed end of the conveyor. Belts with chevron cleats only, and smooth belts are to have heavy-duty, rubber cleaner cleats that drag debris out of the return pan. On sorting conveyors, these cleats are low profile and widely spaced (10 to 40 feet) to prevent interference with sorting.
- Cleats without notches – No return rollers are needed, eliminating the need for disks that have to line up with notches in belt cleats, eliminating the risk of damage if one of these disks slips out of alignment with the notches. It also eliminates any leakage caused by material sliding down the carrying belt through the notches.
- Versatility – Return pans offer more options for adding cleats (see “Cleat Options” above)
- Ease of belt maintenance and installation – Because the belt is supported by the pan the full length of the conveyor (rather than sagging between rollers on return roller conveyors), no tools are required to pull the ends of the belt together when connecting the belt. Pulley removal and installation is much easier, also.
DRIVE METHOD – Parallel gear, shaft mounted, torque arm reducers (Dodge Torque Arm II)
Remcon's preferred conveyor drive method uses a Dodge Torque Arm II reducer driven via separate motor, v-belts and sheaves. These reducers have been used almost exclusively in sand, rock, gravel, mining, etc., industries, for many years, and are well proven. Remcon has used them since 1990, with good success. The new generation has been engineered throughout with features designed to improve performance, extend service life, and reduce maintenance. Remcon's normal configuration of these reducers being driven by a separate motor by v-belts using different combinations of sheave allows for additional speed reduction.
The advantages of using the Dodge Torque Arm II, shaft mount reducer with v-belt drive are as follows:
- Low maintenance – There are no chains to oil, tension, or shorten & reconnect.
- Ease of adjustment – Rather than moving the entire gearbox and motor to adjust the chain tension, the Dodge Torque Arm II reducer only requires loosening two lock nuts, and turning the turnbuckle by hand.
- Fewer wear parts – There are no sprockets or chain to wear out. Although V belts will wear out, they commonly do not wear out until they are protecting the conveyor from jamming (see following item) are inexpensive, and easy to replace. V-belt sheaves last much longer than chain sprockets and chain.
- Jamming Protection – They eliminate the need for mechanical shear pins. The motor drives the reducer by a V-belt(s). If the conveyor jams, the v-belt slips, preventing damage from the jamming. As the v-belt is slipping, it typically makes a loud squealing noise that draws attention to the problem. If the conveyor is not turned off, the v-belt will eventually be ruined, and there will be nothing driving the jammed conveyor. The cost of replacing the v-belt is typically $20.00 or less. Replacing the belt involves opening the hinged belt guard door, loosening the turnbuckle and slipping the new belt on. If the conveyor is prone to jamming (for example wrong product, or too much product), the v-belt can be kept looser than normal to minimize the potential for damage. In the years that we have used these reducers, we are unaware of any Remcon conveyor, equipped with these reducers that suffered damage resulting from jamming. As additional back-up protection, an electronic shear pin may be added to the electrical system.
- Parallel gears – The gears are parallel, rather than right angle. Parallel gears are more efficient and produce less friction.
- Operating and maintenance convenience – When working on a conveyor, such as doing maintenance, un-jamming product or diagnosing problems, there is often a need to move the belt a short distance either forward or backward. This is impossible electrically, since the power should be locked out at this time. This can be accomplished easily and safely without power however, with a shaft mount reducer, by turning the spokes on the input sheave by hand.
- Excellent availability – Unlike other reducers, the Dodge Torque Arm II reducers are so commonly used in other industries that they are quite often in stock at many local dealers, and are almost always available somewhere in the country. Other brands (Link, Browning, etc.,) may also be substituted without modification.
- Separate motor – The motor is mounted separately from the reducer, and is connected only by v-belts. Therefore, any brand of motor can be used, and a motor breakdown does not affect the reducer, or vice-versa.
- Ease of changing reduction ratios – Reduction ratios of up to 5 to 1 are easily obtained from the motor-to-reducer v-belts and sheaves. These ratios are easily changed by swapping out sheaves, which is more difficult and expensive with chain & sprockets.
REMCON BELT TAKE-UPS
Remcon’s cantilevered, telescoping tube style take-ups with manual screw adjustment offer the following advantages:
- Cleaning Access – The take-up frame is positioned to provide access to the area between the upper & lower belts, for ease of cleaning and inspecting the tail pulley.
- Replaceable Parts – Remcon take-ups are comprised of separate, individual components that can be easily replaced as they wear out. The bearings bolt on separately and are the commonly available pillow block style. The threaded working parts of the take-up are separate and easily removed, and are commonly available from local fastener or hardware stores.
- Take-up Travel – Generous length of take-up travel (10” on the shorter conveyors, up to 18” on the longest). On Slider Bed style conveyors, the belt will be cut so that the majority of the take-up travel is used to make the belt looser, for ease of belt installation, repair and replacement. Since good quality belts with polyester carcasses have virtually no stretch after initial tensioning (and in some cases will even shrink slightly), not as much take-up travel is needed for making the belt tighter as the belt is used.
- Ease of Adjustment – Belt tracking and tension adjustments are made with one wrench, with no need to loosen and re-tighten the bearing attachment bolts. The moving parts of the take-up have generous amounts of clearance, to prevent binding in the frame or against the bearings (side load) as the take-up moves through its full range.
- Versatility – Remcon take-ups will accommodate almost any brand of pillow block style bearings (the most common style of bearing).
