Conveyors are at the heart of most material handling solutions

A good conveyor does more than just move material from one place to another. It can be a source of increased efficiency, creating both time and money. Whether you need conveyors for accumulation, product transfers, production line, or packaging, from aluminum to z-frame, WEPCO’s custom-engineered solutions create efficiency.

Conveyor Basics:

GRAVITY Conveyors

GRAVITY Conveyors

GRAVITY conveyors are the indispensable workhorses of warehousing and manufacturing. Instead of motor power, they use slope to move material. They are low cost, flexible, easy to install, and don’t require electricity. Available in roller or skatewheel form, gravity conveyors are often part of an integrated material handling system.

ROLLER Gravity ConveyorsROLLER gravity conveyors can carry heavier items than skatewheel conveyors, and are ideal for conveying uneven, open, smooth or rimmed-bottom packages; wood, fiber or plastic containers; and long, narrow packaged materials. They are not recommended for conveying soft bottom cartons or bags. Roller gravity conveyors can be used for both temporary (lightweight) and permanent (medium- and heavy-duty) installations. The load weight determines the slope for gravity movement. Curves, spurs, switches and gates make them versatile.

SKATEWHEEL gravity conveyors

SKATEWHEEL gravity conveyors are more economical than roller conveyors. They work at less of a decline angle than gravity rollers and flow more easily, especially over longer lengths. They move items with flat, smooth bottoms, and work best with evenly loaded cartons and totes. The denser the skatewheel pattern, the greater the range of cartons that can be handled. Their light weight makes them ideal for temporary conveyor lines.

BELT Conveyors

BELT Conveyors BELT conveyors move loads on belt surfaces traveling over either a metal slider bed or rollers. They are an economical way to convey nearly anything while maintaining separation of items on horizontal, inclined, or declined paths. They are widely used in manufacturing and distribution applications for products that cannot be conveyed over rollers – irregular bottom surfaces, small items that would fall in between rollers, or bags that might sag between rollers. Belt conveyors transport light- and medium-weight loads between operations, levels, departments, even buildings. Three things are considered in deciding which belt conveyor to use: the product’s physical characteristics, the operation to be performed, and the environmental conditions of the facility.

SLIDER Bed Belt Conveyors SLIDER bed belt conveyors are made of a sheet metal frame with rollers at either end. The belt slides across the smooth metal surface, making a quiet, inexpensive, easily-installed conveyor. Suitable for light- to medium-weight loads, it is one of the most popular conveyor types for small items, cartons, totes, parts, and oddly-shaped items (not recommended for bulk or granular materials.) Because it maintains product spacing and orientation, it is also good for sorting, inspection, progressive assembly, and packing.

ROLLER Bed Belt Conveyors ROLLER bed belt conveyors have channel frames which use a ‘bed’ of rollers to support the surface of the belt. The reduced friction allows it to carry heavier unit loads and provide greater capacity than slider bed conveyors. Because it can maintain its belt tracking alignment better than a slider bed, it can be used with pushers, sorters, and plows. Like the slider bed conveyors, it maintains product spacing and orientation and is good for progressive assembly, sorting, packing, and inspection. It can also be used in pallet handling applications when pallet runners are inconsistent. The wire mesh belt option can carry hot or cold parts from ovens or freezers and allow for drying.


POWER ROLLER Conveyors POWER ROLLER conveyors are used when higher capacity is called for, and to avoid belt tracking problems while diverging or converging packages. They are used for transporting flat-bottomed items. Power roller conveyors can be driven by chain, belt, or lineshaft. Chain drives work well for higher speed applications and certain environmental conditions such as oily manufacturing processes. Belt drive excels for higher speed applications and where merging positive product flow is required. Lineshaft power is economical, easily modified, works well for quiet handling and complex operations, and can be used with pop-up diverts, curves, spurs, and transfers with no additional drives or motors.

ACCUMULATION Conveyors ACCUMULATION conveyors organize transported materials for further handling processes. The drive pressure on the product can be adjusted or eliminated, allowing packages to be distributed in fixed or dynamic spacing intervals and accumulated on multiple conveyors prior to the next operation – sorting, loading, palletizing, etc. Precise controls can be mechanical or electrical, contacting or non-contacting.


  • MOTORIZED accumulation conveyors — work from electrical controls and are used in curves, inclines and declines. Each zone is powered by a motorized roller which drives the remaining rollers by o-rings.
  • MINIMUM PRESSURE accumulation conveyors — allow products to touch each other lightly while being accumulated. They remove enough power from the tread roller to stop a moving package without causing product-damaging back pressure.
  • ZERO PRESSURE accumulation conveyors — have sensors at regular intervals that remove pressure from the preceding zone so products do not touch each other while being conveyed.
