Rolling conveyers are operated manually, by gravity, or as a powered conveyer using belt or chain to drive the rollers. The simple design and operation of these conveyors keeps maintenance costs to a minimum and makes them relatively cheap to buy. Depending on what they are going to be used to convey, a set of steel, plastic, or rubber coated rollers, with a shaft and bearings through the centre, are slotted into a metal frame.
Although often fixed on legs at regular intervals along the length of the frame, they can also be slotted into a purpose built housing as part of a manufacturing set-up. Width of rollers and frame, and length of frame, is often determined by the type of materials, packages or baggage which is to be conveyed or transported along the track.
Unless ordered for a specific job, they are often bought in sections of around six foot in length. These short sections are then easily manhandled around manufacturing facility or warehouse, to make up a rolling conveyer of any length required. With the addition of curved corner sections using tapered rollers, the conveyor can be utilised in a number of different configurations for the movement of products from one area to another.
All that is required to change the conveyor from manual operation to gravity feed is the feed end raising, or the receiving end lowering. The amount of incline required will depend on the material and weight of the objects or packages to be moved. As a general rule, the lighter the object the greater the incline.
Gravity roller conveyors are also very popular in warehouses and pay and collect retail businesses as part of a stock shelving system. Lengths of rollers are set slightly raised at the rear and adjustable dividers are employed to accommodate the different widths of boxes or goods stored within the system. As the front item is removed, those remaining move forward to fill the space. Loading the shelving can be achieved from the rear or from the front, depending on the configuration of the shelving.
Rolling conveyers are as at home as part of a fully automated manufacturing system as they are being used in factory, warehouse, airport, docks or parcel sorting depot. Mobile rolling conveyers are often employed in docks or airports to facilitate quick and easy off-loading of goods and passenger luggage, where cargo doors of ships and aircraft are at varying heights from the ground.
Available off the shelf in a range of widths and lengths, or purpose built for a range of different applications, rolling conveyers provide the perfect cost effective solution for the easy movement of manufactured and stored goods, baggage and freight handling needs across a wide range of industries.
