The link and flightassembly is made easier by attaching the flight to the chain link using astandard bolt and nut, with a high case hardness and high tensile hollow pin.Traditional chain systems have used pins and circlips. The problem with thissystem is that during any maintenance repairs on the chain, the whole chainwould have to be lifted out of the conveyor to conduct repairs. This results inlarge down time in production and high maintenance costs.Image of Bolt ‘n’ Go assemblyWith the Bolt ‘n’ Go system, to conduct repairs such as to change flights or pinscan be done inside the conveyor, without even taking the tension out of thechain. Instead of welded flights, we are using bolt on flights, and again thesecan easily be changed without any fuss.

With the Bolt ‘n’ Go system, the pins, chainand flights are secured using a secured lock nut, which securely holds thesystem together in a consistent manner, but also facilitating easy and saferemoval when required.One of the first installations to use this system was in November of 2006 atCHS, Superior, WI. The facility handles several commodities which includewheat and soybeans at the rate of around 1.0 million tons per annum. Theyhave several drag conveyors which use drop forged chain, with the traditionalpin and circlip assembly. While this has proved a reliable assemble method forthem, it has proved time consuming when changing out bent or broken chainflights.

TheBolt ‘n’ Go chain is very easy and fast to install and maintain, as you eliminatethe need to separate the chain each time while installing a new flight. Also thereis no need to slacken of the chain or re-tension while changing flights. Thisalone will save untold hours on the routine maintenance of these conveyors” Hegoes onto to say “the Bolt ‘n’ Go system has been in service for well over 12months, is running great and no problems”.

The system uses heavy duty Nylon flights,which bolt straight through the pins, with no need to bolt on or slide overexisting steel flights. The Nylon flights also have excellent wear, strength andresistance capabilities.The Bolt ‘n’ Go pin / bolt assembly system can also be used with the traditionalwelded flight system, to replace the traditional pin and circlip arrangement. Thislike the Bolt ‘n’ Go flight system is very easy to change over to for themaintenance team on site.
