What is Gravity Roller Conveyor? A gravity roller conveyor moves loads down the conveyor without the use of motor power sources, usually using an incline and gravity or by being pushed by other conveyed items. This conveyor is used primarily to transport cartons, cases, packages and/or pallets over shorter distances. Gravity conveyor is among the most common pieces of equipment found in many warehouses.
Roller conveyors are used in all areas of the warehouse. They are especially ideal for use on shipping docks and in warehouse pick & pack operations.
Gravity Roller Conveyors can be used when conveying loads with flat, smooth bottomed surfaces, as well as most items with an uneven bottom surface such as drums, pallets, cans, molds, etc.
Using appropriate diameter roller sizes, roller spacing, and width between frames, many types of loads can be conveyed. Typically, gravity roller conveyor has a capacity of up to 3,000 lbs.
While available in any length you need, gravity roller conveyors are typically sold in 5- or 10-foot sections. The most common overall widths are 12", 18", 24", 30" and 36", which are considered industry standard. Several different roller sizes and types are also available for custom applications.

There are many different styles of conveyor to choose from. The first question you need to ask yourself would be if you want a gravity or powered conveyor solution.
Gravity conveyor consists of either roller or skatewheel types. Powered conveyor options are more complicated because of the vast variety of options. Some examples of powered conveyor include accumulation conveyor, belt conveyor, lineshaft conveyor, sliderbed conveyor, telescoping conveyors and trash conveyor.
Powered conveyor systems are usually either belt driven, belt over roller driven or chain driven.
Roller conveyors are a form of conveyor that uses gravity or manual pushes instead of electrical power sources to move objects from one place to another. Using rotating rollers that are spaced evenly apart, loads or objects can be moved down the line with a simple push or by letting gravity do the work. Both gravity roller conveyor and skatewheel conveyor are examples of roller conveyors.
The rollers on gravity conveyor are the only part of the gravity conveyor system that actually moves. The rollers (or wheels) rotate when an object is swept over them, causing more rollers (or wheels) to rotate when they come in contact with the moving object. After the load has finished passing over each roller, the rollers stop rotating and won't begin to spin again until the next load comes along.
A gravity roller is a long cylinder shaped roller that spans across the entire width of the conveyor section. Several rollers with the same diameter are placed next to each other at even intervals so the load smoothly slides over the surface of the conveyor.
A wheel conveyor consists of several small skatewheels evenly mounted on shafts across the width of the conveyor frame. This is also known as skatewheel conveyor and is often used for moving lighter weight objects with smooth bottoms.
