Mechanical Platform Scale

The steel-yard is made of special steel, zinc plated and is graduated accurately to the full capacity of the machine by means of machine cut notches. This system gives quick and accurate weighment without the need for loose weights. Wear & tear of the notches is minimise to a great extent by a special notch protection bar as illustrated. A quick-tumbler locking device is provided to hold the steel-yard while loading and unloading for minimising wear & tear of knife edges & bearings. Major poise is mounted on roller bearings for smooth movement. The brass polished bracket which carries the brass polished scale, engraved with marking is fixed at an angle to the steel yard for easy reading. The brass polished minor poise moves on it for final reading. Balance box at pillar end of the steel yard is provided for quick zero adjustment. Sensitivity ball incorporated in it for restoring original sensitivity instantly.
