The Rice Lake Master™ 421 Belt Scale Weigh Frame is a compact, lightweight, and efficient weighing solution for light capacity and low-density materials, especially suited for flat belt conveyors used in food production, granular material handling, and agricultural processes.
Its two BM11 bending beam load cells are hermetically sealed and mounted externally for enhanced durability and environmental protection. The load cells are attached via adjusting plates on the outside of the conveyor stringers, offering a stable base and simple integration without significant modifications. The open design not only makes cleaning hassle-free but also promotes hygiene—ideal for food environments.
With support for belt widths from 12 to 60 inches and a max capacity of 30 tons per hour, the 421 frame provides accurate performance at speeds up to 400 feet per minute (2 m/s). It’s also built to handle inclines up to 10 degrees and is available in both powder-coated mild steel and 304/316 stainless steel, depending on your environment's demands.
