1. the structure is simple, low power transmission link, simple installation and convenient;
2. the unique rectangular lever, steel is good, becomes invisible;
3. using a rubber trunnion bearing, anti-corrosion, moisture-proof, anti-vibration;
4. resistance to lateral forces, anti horizontal component, effectively reducing the belt deviation and blanking partial load on the system accuracy;
5. two load cells by partial load is small, smooth, high precision;
6. 17A weighing wide area, four sets of rollers so that the impact on the belt weighing a minimum;
7. 17B double roller, weighing shorter zone for feeding short distance belt conveyor.
