Now, let’s help you get an answer to the question ‘what is a conveyor belt?’


A conveyor belt is the carrying medium of a belt conveyor system, one of the many types of conveyor systems available today. Each conveyor system requires different modules in order to function properly and do the tasks required by the belts. The different tasks can range depending on the weight required, the speed required, and the throughput of products on the conveyor system. A conveyor system consists of two or more pulleys (referred to as drums), with an endless loop of carrying medium – the conveyor belt – that rotates around them creating a pull effect for the goods it’s carrying. One or more of the pulleys will be powered moving the belt and the material on the belt forward and along the system.

Structure of a Conveyor Belt

Belts consist of one or more layers of material. It’s common for belts to have three layers: a top cover, a carcass, and a bottom cover. However, there are situations where more layers are needed depending on the goods being moved on the conveyor system. The purpose of the carcass is to provide strength and shape to the conveyor system and is often a woven or metal fabric having a warp & weft. 


The warp refers to longitudinal cords and defines the running properties of the belt due to it being responsible for the level of resistance and elasticity of the belt. The weft represents the whole set of transversal cables allowing the belt to be resistant to cuts, tears, and impacts while also being highly flexible to ensure the system doesn’t break easily.

The lower strength

The most common carcass materials to be used are steel, polyester, nylon, cotton, and aramid while the covers are usually various rubber or plastic compounds specified by the use of the belt. If the conveyor system is carrying heavy goods, steel conveyors can be used due to their high strength and increased durability. The steel conveyor belts are made of steel cords compared to the lower class strength ones that use polyester, nylon, and cotton. The lower strength the material used or conveyor system installed will reduce the amount of energy consumed for operation while also increasing the product life and enhance productivity. A fundamental part of a conveyor system to ensure the smooth running is a Drive Arrangement, which comprises of Gear Boxes, Drive Motors, and associated couplings. On top of this, there are several parts that can be used or are needed for a functioning conveyor system.


Scrapes are used to clean the belt, chutes control the discharge direction, and Skirts are for containing the discharge on the receiving belt, Take Up assembly for “tensioning” the belt and Technological Structures like Stringer, Short Post, Drive Frames, and Pulley Frames make up the balance items to give you a full operating belt conveying system. Within the food industry, you will see conveyors in a blue material. This means they are washable, also known as wash-downable, in order to comply with hygiene laws for food.


A conveyor belt is a critical component in various industrial applications, facilitating the efficient transport of loose materials and heavy-duty items across different stages of production and distribution centres. At LAC Logistics Solutions, we offer a wide selection of belt conveyors designed to meet exact requirements, including medium duty belt conveyors, incline belt conveyors, and portable conveyors. Our products feature robust construction using materials like stainless steel, mild steel, and high-quality rubber conveyor belts, ensuring durability and reliability.

History of Conveyor Belts

Conveyor belts have been used since the 19th century. It was in 1892 where Thomas Robins began a series of inventions that led to the development of a conveyor system being used to carry coal, ores, and other products.


Henry Ford introduced conveyor-belt assembly lines at Ford Motor Company factory which introduced the possibility of mass production and batch production.


There are two main industrial classes of belt conveyors; general material handling and bulk material handling. Depending on what your conveyor belt system will be doing will decide what type of belt you will need to carry your goods.

This involves moving materials, products, items across short distances within the confines of a building or between a building and a transportation vehicle like they do at a Hermes national sorting hub. These belts are used for moving smaller sized and lower weight items such as moving boxes along inside a factory.
This is where the conveyor system needs to handle large volumes of raw goods, sharp heavy materials, dry materials, or metals. Examples of bulk materials are minerals, ores, coal, sand, stone, and chemicals, grains, flour, and sugar. This makes bulk material handling conveyorS useful for industries that produce bulk materials such as food and drink, tobacco, metals, painted goods, animal food, agriculture, ceramics, and chemicals.


Conveyors can be used across various industries but are extremely popular within the distribution and warehouse space as well as in the manufacturing and production industry. They are installed in places like Hermes national sorting hub and have seen massive success from installing an automated conveyor system into their national hub due to the increased throughput the systems can handle. Due to conveyor systems being adaptive, they are able to be used in most industries due to the variation of weight, length, and items they can carry.


Conveyor belt systems aren’t just used for big products and carrying heavy materials though. If you’ve ever been to the Japanese food chain YoSushi you will have most likely grabbed one of your plates off them as they interwind round the restaurants seating plan. These type of conveyors use a rubber material to convey irregular items with small surface areas which stop the goods or plates falling between sections. Belt conveyor technology is used in moving people in public places such as the moving isles between terminals at an airport, escalators in a shopping centre, transporting skiers up a slope, or moving your items down the line at the checkout in your local supermarket. You’ll find in some cases there are extremely long belt conveyors installed to transport items and goods. Dubai International Airport has the longest conveyor system in the world for their baggage handling system which is a mixture of different belts and features for a baggage handling system at a combined length of 39 miles.

Why Do People Use Conveyor Belts?

Conveyor systems can be used for a variety of reasons but are mainly used for labour cost-saving while increasing throughput on a section of the production or transportation process which of course means they can get more products manufactured or sorted and sent out to customers in a quicker and more efficient manner. Due to reduced labour being needed to carry out the task, the conveyor systems usually reduce the space required to move items, allowing the process to run in a smaller section of the facility and freeing up working space.


Belt conveyors are the most commonly used power conveyors because they are the most versatile and the least expensive while being able to carry a variety of shaped objects, large or small, light and heavy, jigged edges or square boxes. You can hire conveyor belts for a certain amount of time, with this process being popular within the house building and landscaping industry where they are timed projects in a specific area where it wouldn’t make sense to install a whole conveyor system.

Variation of Uses

To make sure items can go round the system in the correct way, belt conveyors can be manufactured with curved sections which use tapered rollers and curved belting which can have additional pieces such as guards, gates, convergers, RFID scanners, and more to ensure easy access to different sections and no damage of goods. A reason why these type of systems are popular in the logistics, postal sorting, and warehouse industries. Belt conveyors can be used to transport items through elevation, another reason why companies and industries use them. 


If you’ve ever flown into an airport it’s usual to go through baggage collection on arrival. Have you noticed what the luggage goes round on and how it gets fed into visible sight? Sometimes you might see the luggage come down from an elevation on a declined conveyor belt. Another example of elevated conveyors being handy is within handling raw materials. Elevated conveyor systems come in handy when moving coal, grains, sand, gold, sulfur, and many more raw materials. They can be transported over gentle slopes or gentle curvatures and this is where a toughed belt conveyor would be used.

Belt Conveyor Safety

Any type of conveyor system carries safety risks if not properly identified, accounted for, and the safety guidelines and rules are adhered to. Depending on where the conveyor system is used depends on what health and safety measures need to be taken. For example, if you’re moving heavy-duty goods on an incline that goes through a process of going through different sections you’re going to have stricter rules and make adjustments to ensure the products stay on the conveyor system compared to small food plates going round on a sushi belt conveyor as mentioned earlier.


Conveyors used in industrial settings include tripping mechanisms such as trip cords along the sides of the conveyor with safety start-stop buttons to ensure operators can shut down the conveyor with immediate effect if a problem arises. To make sure you’re purchasing a conveyor belt system from a company that is responsible and takes health and safety as a paramount feature of their business service, make sure they have accreditations such as ISO 9001:2015 and have a SafeContractor approved status.


There are a range of systems that can be used and installed into a conveyor system and to safeguard them from risks and hurting an operator of the system and can allow a system to slow down or stop a system if a belt loses structure alignment. These include belt switches, speed switches, a belt rip switch, and emergency stops.


Our comprehensive range of belt conveyors includes standard belt conveyors, flat belts, modular belts, and specialised incline conveyors, all customisable with various motor options and drive units such as powered pulleys and drum drives. We also provide variable speed controllers to manage the maximum speed and direction of conveyor systems, making them adaptable for different quantities of materials and incline angles.
