We offer two types of expandable gravity conveyors: Skatewheels and rollers. The Skatewheels are suited for rigid boxes, whereas the rollers can better accomodate slightly soft packaging, thin-skinned boxes, or slightly odd shapes.
In each case, when fully expanded, the minimum box/product size if about 400mm in the direction of travel, as standard. However, we can provide shorter pitches on request, permitting box sizess down to 180mm.
As standard, the units are supplied with 127x38mm castors featuring combined wheel/swivel brakes. However, we can provide them with a larger 150mm castor if you prefer. (this makes it much easier to maneuver)
The units are available in three widths: 450mm, 600mm and 750mm. They can be made in any length you require. In addition, smaller units can be 'daisy chained' together to form longer lengths.
Whether skatewheel or roller, the conveyor is 'self tracking', so that packages will follow the line of the conveyor no matter how much it is curved, and will not fall off.
The conveyors have adjustable, telescopic legs to give a working height (to the top of the roller or skatewheel) of between 720mm and 1000mm. (this is slightly higher if the 150mm castor wheels are used).
The more economical of our two flexible conveyor solutions. The Skatewheels are suitable for rigid packages of 350mm length or greater (fully expanded). The skatewheels come in either blue nylon for light duty applications, or heavier-duty zink-plated steel that can give a loading capability of up to 300Kg per meter !
This is better suited for slightly 'floppy' packages, or thin-skinned boxes, or non-standard shapes. The full-width rollers give a more consistent support across the width of the package.
It is slightly lighter-duty than the skatewheel conveyor, with a maximum load of 220Kg per meter.
In other regards, it is the same as the skatewheel conveyor, with the same accessories options.
As a rough guide, the conveyors expand to approximately three times their collapsed length.Example lengths:
