It consist of a continuous chain running on or in an overhead track, with the loads on carrier suspended from the track and moved by the chain. A chain carries running trolleys on a suspended rail, and is driven by one or more motor-reduction units. Equally-spaced hooks on this chain are used to suspend the loads. An overhead conveyor can advance either by steps or
continuously in a given plane or in the volume. Wire Rope drive is also possible.
Overhead Chain Conveyors can move isolated fragile loads that should not come into contact with the ground for reasons of hygiene and/or deterioration of the product being transported (thus avoiding reject). Overhead chain conveyors provide easy access to the transported item from underneath. This versatile conveyor releases valuable floor space for production, processing machines, and workin- progress. In addition, overhead chain conveyors can be used to accumulate, transport, and sort products.
Advantages
Disadvantages
In service, the trolley wheels and chains begin to wear over time. Points of wear include the bearing races within each wheel, and the joints between chain linkages. After a relatively short period of time, such as one year, the trolley and chains must be replaced to avoid the entire conveyor system binding and bringing the conveyor to a sudden halt. This frequent replacement can be an enormous expense for companies, especially if the trolley and linkages support very heavy objects, or if the conveyor system is lengthy.
Therefore, it is very advantageous for companies to prolong the life of their overhead conveyors by regularly applying a lubricant thereto, as it is less costly than replacing the conveyor. This is especially true for the more expensive heavy-duty chains and trolleys.
However, it is important to avoid having lubricant drip from the overhead conveyor onto the objects being conveyed. For example, in poultry processing plants, the conveyor system is used to carry a bird to and from the numerous work-stations as the bird is processed. Because the conveyed material is a food product, an essential performance criteria is that the conveyor and bird are kept clean of oil and other types of contamination.
Situation in Environment
An overhead conveyor may operate at high temperatures (for example, thoseof an oven). Sensing devices may be required to resist temperatures of 250°C(resisting detection).The electrical equipment of the conveyor is generally incorporated in acommon cabinet. Except for the cabinet seal, ventilation, and (if necessary)heating, no recommendations are necessary.
Examples of Use
• Laundering or cleaning clothes
• Treating the surface of parts (e.g., soaking, painting, varnishing) in iron
and steel industry, metallurgy, joinery
• Handling and assembling of sub-assemblies for automobile industry
• Assembling and testing household appliances or data processing
stations in the electronics industry
• Safety stocking of diverse parts
• Cooking food products (e.g., ham or poultry)
• Storing and deep freezing butchered meats
Lastest trends/ types of overhead chain conveyor
The invention relates to a mono- or twin-rail overhead chain conveyor, in particular for transporting heavy loads such as motor vehicle parts, having a chain track in the form of an I-shaped profile with running gear which can move along said track and having roller blocks for mounting rollers which are supported on the chain track, said roller blocks being connected to a traction means for pulling the running gear and said running gear being designed for a mono-rail overhead chain conveyor in the form of loading running gear and for a twin-rail overhead chain conveyor in the form of towing running gear which interacts with loading running gear movable on a load rail running below the chain track.
Mono- and twin-rail overhead chain conveyors are continuous conveyors in which the conveyed material is always transported underneath a single-stranded traction means, i.e. suspended. The conveying process is positive here, with the conveying track being disposable anywhere within the area and with curves being possible in both the horizontal and vertical planes.
As a general principle, steel chains in the form of bolt-linked and flat-linked chains are used as the traction means. Steel ropes or textile ropes are only possible for lightweight mono-rail overhead chain conveyors, so that positive drives are automatically assured as a rule.

In addition, overhead chain conveyors can be used to accumulate, transport, and sort products.
Advantages
Compact – Small track cross-section and small radius horizontal and vertical curves allow installation in confined areas and take fullest advantage of available space.
Economical – Most systems can be powered by one drive, including curves and inclines. Fewer drives mean lower operating and maintenance costs.
Safer – Tubular, enclosed track design reduces the chances of injury because the moving chain is inaccessible to casual contact.

This recurrent spare can be an enormous expenditure for businesses, particularly if the trolley and connections support very heavy substances, or if the conveyor systems suppliers.
Halo,I'm Helena Julio from Ecuador,I want to talk good about Le_Meridian Funding Service on this topic.Le_Meridian Funding Service gives me financial support when all bank in my city turned down my request to grant me a loan of 500,000.00 USD, I tried all i could to get a loan from my banks here in Ecuador but they all turned me down because my credit was low but with god grace I came to know about Le_Meridian so I decided to give a try to apply for the loan. with God willing they grant me loan of 500,000.00 USD the loan request that my banks here in Ecuador has turned me down for, it was really awesome doing business with them and my business is going well now.
