Load cell scale electronic weighing for crane etc.
THE RIGHT SYSTEM WHEN YOUR PROFITS DEPEND ON ACCURATE READINGS.
IT IS A KELBA KT 12000 LOAD CELL. DESIGNED FOR USE IN A CRANE STRING OR TO READ ANY SUSPENDED WEIGHT UP TO 12 TONNES EACH e.g. A BAG LIFTER.
IT HAS TWO 36MM DIAMETER HOLES AND IS DESIGNED TO ACCEPT 35MM SHACKLE PINSTHE CELL WORKS IN TENSION - NOT BY BENDING (AS WITH SHEAR BEAM TYPE LOAD CELLS).THE 12000 KG IS A SAFE LOAD FOR WEIGHING. ACCORDING TO THE MANUFACTURER THEY WILL ACCEPT 36000 KG EACH. A READER/INDICATOR IS NEEDED TO DISPLAY THE WEIGHT, AND IS NOT INCLUDED IN THIS SALE. INDICATORS ARE NOT NECESARILY PROHIBITIVELY EXPENSIVE. THERE ARE OPTIONS AVAILABLE DEPENDING ON WHAT YOU WANT THE READERS TO DO.THE ACCURACY RESOLUTION OF THIS CELL WILL BE FAR BETTER THAN ANY HYDRAULIC GAUGE OR SPRING BALANCE SYSTEM.
IT IS THEORETICALLY POSSIBLE TO READ TO A ACCURACY OF WITHIN 1 KG DEPENDING ON THE SETUP AND THE DEADWEIGHT IN THE SYSTEM. RESOLUTION IS MORE A FACTOR OF THE INDICATOR THAN OF THE CELL. One kilogram is not very realistic because most loads wont sit still long enough to allow the reading to be taken. Ten kg is probably more realistic with big loads, especially if on a mobile machine or crane. For example wind, load swinging or the vibration from a running motor will make a fine tolerance reading almost impossible. I am not guaranteeing what resolution can be achieved . That is totally dependent on factors beyond my control.
IT IS IN USED CONDITION BUT WAS ONLY USED ONCE TO LIFT ONE LOAD AND DEEMED THE WRONG TYPE FOR THE PROJECT AT THE TIME.
IDEAL FOR WEIGHING PRODUCT SUCH AS CONCRETE INGREDIENTS, GRAVEL, SAND, MULCH, COMPOST, STOCKFEED, FERTILIZER BAGS, TANKS OF LIQUID ETC. ETC.. ALMOST ANYTHING THAT CAN BE SUSPENDED.ACCORDING TO THE FACTORY SPEC. SHEET THEY ARE ACCEPTABLE FOR EXPLOSIVE ENVIRONMENTS PROVIDED INSTALLATION IS CORRECT.
