We have just installed a conveyor system for a major catering supplies company in their central warehouse. Orders received are rapidly processed, and picked items are handled in plastic boxes. The boxes are moved by the conveyor system to a high-level mezzanine floor via a powered belt and roller line and then onto a long decline gravity roller section. A second line moves boxes down to an intermediate mezzanine floor via a combination of gravity and powered roller and powered belt conveyors. Each line has its own set of controls. The following pictures illustrate the system installed, which on the 'up' line had to be fitted into a very confined space with special attention being given to incline angles and transfers.
