The pit frame for scale installation has been designed for stable and safe mounting of platform scales in the floor. It enables flush installation of the scale with the floor level, significantly improving the transport and weighing of goods using pallet trucks and transport carts. The frame structure ensures proper positioning of the scale and increases everyday working comfort in warehouses, production halls, and logistics centers. The recessed installation minimizes the risk of mechanical damage to the device and improves the ergonomics of the weighing station. The frame is intended for 4-load-cell scales and is made of durable materials ensuring many years of operation even in demanding industrial environments. Its compact dimensions allow convenient integration with facility infrastructure.
