Rigid gravity roller conveyors

The common image of a gravity roller conveyor is a long, straight conveyor running down the side of a factory, with lots of boxes trundling down it. And indeed it is used in this capacity with great success. It is reliable, long-lasting, and inexpensive compared to the equivelant powered conveyor. However, Gravity Roller conveyors can do much more than this.

Gravity Roller Conveyors - with their relatives, the roller table - can form merging and splitting lanes, T-spurs, curves and bends, and be equiped with rollback preventers, roller-brakes, and even pedestrian bridges.

Gravity ball table


Roller ball tables complement gravity conveyors, and consist of a table with a group of upward-facing captive balls, forming a surface that allows packages to glide over it, and also to change direction under human control. This in turn allows the use of 90-degree spurs from a main conveyor line. (these are illustrated in the video below).


CCBA is able to supply complete gravity roller conveyor systems to your requirements, ranging from lightweight packaging units to heavy-duty pallet moving conveyors. We can fit variable-height telescopic legs, as well as screw-feet for fine adjutment, side-guides and end-stops, and the previously mentioned bends, corners, rollback preventers, brakes, and bridges.



We have a little video below showing some recent installations that feature many of these features. (contains commentary and cheesy music, so turn your loudspeaker on if you have one)

Notes and queries: What IS a "gravity roller" conveyor ?

The term is often assumed to mean a slightly inclined roller conveyor, in which packages literally roll down the unit under the influence of gravity. And - of course - this IS a popular configuration. Any unit that inclines by more than 3% WILL - subject to friction - allow packages to start rolling.

This is not always entirely succesful however; bend units in particular can be notoriously fickle, especially with packages of different sizes and weights. The packages will attempt to move sidways onto the outside radius of the bend, and can often jam. The bend CAN be 'cambered' to prevent this, but the camber will only be effective against a specific weight and size of package.

However, frequently these conveyors are NOT inclined, and are used to either accumulate packages, or to allow a human operator to shepherd them along, or even used as workbenches. Utlimately, the primary purpose of a gravity roller conveyor is to avoid the need to physically carry a heavy package along a warehouse floor !

In cases where "gravity" conveyors can't handle the task, an inexpensive option is a powered "lineshaft" roller conveyor. Our sister-company, Central Conveyors Ltd, can offer a wide range of solutions for Powered Roller systems.
