    Modular Mini Chain Belt Conveyors

    Image of System. Front orientation. Contains Annotated. Conveyors. Modular Mini Chain Belt Conveyors.
    Build a mini conveyor in any shape you need. These conveyors have curved, straight, incline, and decline runs that you can quickly join together with the included brackets. They're often used in areas with limited floor space and applications that require frequent layout changes. To customize your conveyor, add on components, such as package stops and merge guides, with the built-in T-slots on the side. These conveyors come with guides installed.
    You'll need a drive assembly, an idler assembly, and a belt to complete your conveyor. To determine the belt length you need, multiply your conveyor’s length by 2.1. If you need a belt longer than what’s available, you can connect multiple together. Use a belt installation tool to pull out the pin, then line up two ends and push the pin in with the tool to connect them. You can also shorten a belt using the same tool.
    Maximum run length is 70 ft. with two 90° curves. Adding more curved conveyors will reduce the run length.
