4B drop forged chain is used to convey granular material using 2 principle alternative technologies: en-masse conveying and drag conveying.
4B forged chain allows for many different flight variations to be used in order to convey different materials in the most effective way. These include: T Flights, U Flights, O Flights and double O Flights.
Due to 4B\'s excellent material selection and heat treatment processes, 4B forged chain links have a superior range of tensile results, often much higher than other manufacturers in the market.
The flagship of 4B’s chain range is the Bolt n Go System. This revolutionary new method for flight installation and chain assembly uses hollow pins and bolts instead of welding, providing significant benefits! Welding of chain flights is eliminated, Maintenance and Flight Replacement can be done without the need to slacken or remove the chain from the conveyor.The chain links are securely connected by a bolt and locknut instead of less reliable pin and circlip , where the circlip is prone to coming loose or breakage.
4B offers a full range of accessories including: Sprockets, Trailers, Nylon flights for scraper chains, flight sleeves and Round link chain.
4B offer a free design service for both new and existing chain conveyors and technical support from a team of specialised Engineers.
