SLIDER BED CONVEYORSSlider 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.

Conveyor Orientation Options
Remcon can build slider bed conveyors in many different orientations, depending on the layout requirements, etc. We also can build two separate conveyors that run in series, to simplify installation, separate clumps better, or to be able to use two different types of conveyors (e.g. a roller chain feeding a slider bed, etc.). Other options may also be available, depending on the application.
All of these orientation options can be installed both in-ground (in a pit) or above ground.
Contact us to discuss what layout options would work best for your situation.

SLAT BED DESIGN
The conveyor bed, which the belt slides on, is constructed of slats, rather than solid steel. A solid bed traps both small debris and moisture underneath the belt. The debris causes increased friction and wear on both the belt and the bed. The moisture, which can include sticky liquid from containers, causes suction and drag on the belt. The slat design allows this debris and moisture to escape from between the belt and the bed, falling between the top and return belts, off the edges of the return belt, and into the return pan, thus preventing these problems.
REPLACEABLE BED SLATS
The bed slats on Remcon conveyors are designed to be easily replaceable if they do eventually wear out or get damaged.
BELT EDGE SEAL
The edges of the belt are sealed by raised (troughed) side bed slats to prevent glass and metal debris from working under the belt edge and causing premature belt wear.
SELF-CLEANING RETURN PANS
Remcon conveyors are designed with a pan that fully encloses the return belt for safety and to collect debris that clings to the belt. The debris is pulled to Clean-Out Openings along the length of the conveyor or a to a collection area at the in-feed end of the conveyor, making for a clean, safe floor area under the conveyor (for complete description see below).
CLEAN-OUT AREAS
Debris that falls off the return side of the belt is contained in return pans to prevent material spillage. Depending on where on the conveyor the debris falls off and what type of conveyor it is, the conveyor "self cleans" the debris to different clean-out locations:
REMCON BELT TAKE-UPS
Remcon’s cantilevered, telescoping tube style take-ups with manual screw adjustment offer the following advantages:
BELT TRACKING
Adjustment for centering conveyor belt is provided on both ends of conveyor.
DRIVE METHOD – PARALLEL GEAR, SHAFT-MOUNTED, TORQUE ARM GEAR REDUCERS (DODGE TORQUE ARM II)
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 re-engineered throughout with features designed to improve performance, extend service life, and reduce maintenance. Remcon normally configures these reducers to be driven by a separate motor by v-belts, using different combinations of sheaves for additional speed reduction.

CLEAN-OUT AREAS
Debris that falls off the return side of the belt is contained in return pans to prevent material spillage. Depending on where on the conveyor the debris falls off and what type of conveyor it is, the conveyor "self cleans" the debris to different clean-out locations:
- For inclined conveyors – Debris that falls off the return belt slides down the enclosed return pan (or is dragged down by cleats) to the bottom of the incline to a guarded clean-out area, preventing the unsafe build-up of material underneath the inclined portion of the conveyor.
- For horizontal conveyors – Debris that falls off the return belt in the horizontal section is dragged towards the tail end of the conveyor by cleats (or a wiper cleat, if there are no other cleats) to a clean-out area at the tail end of the conveyor, preventing the unsafe build-up of material underneath the horizontal portion of the conveyor (or in a pit, etc.).
- For longer horizontal conveyors – Debris that falls off the return belt is dragged towards the tail of the conveyor by wiper cleats. Openings in the pan bottom spaced along the length of the conveyor allow this debris to fall out of the return pan into a removable clean-out tray. This prevents the material from dragging through the entire length of the return pan, causing wear or excessive build-up.
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).
BELT TRACKING
Adjustment for centering conveyor belt is provided on both ends of conveyor.
DRIVE METHOD – PARALLEL GEAR, SHAFT-MOUNTED, TORQUE ARM GEAR REDUCERS (DODGE TORQUE ARM II)
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 re-engineered throughout with features designed to improve performance, extend service life, and reduce maintenance. Remcon normally configures these reducers to be driven by a separate motor by v-belts, using different combinations of sheaves 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 and reconnect.
- Ease of adjustment – Rather than moving the entire gearbox and motor to adjust the chain tension, adjusting the Dodge Torque Arm II reducer only requires opening the hinged door on the belt guard, loosening the 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, if it jams (see following item). They are inexpensive and easy to replace. V-belt sheaves last much longer than drive chain sprockets and drive chain.
- Jamming Protection – The need for mechanical shear pins is eliminated. The motor drives the reducer by v-belt(s). If the conveyor jams, the v-belt slips, preventing the jam from causing damage to the conveyor. 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 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 past 12 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 jamming 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. But this can be accomplished easily and safely without power when using a shaft-mounted 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 a drive chain & sprockets.
