CraneSmart load cell

I feel obligated to mention this, as I have recently talked about the CraneSmart system. To my surprise, a load I was picking the other day that indicated 14,000 lbs (including the 300 lb load block so the load was 13,700) when taken to the crap metal dealer with their for sure accurate scales indicated the load weighed 15,600 lbs. So.... almost a ton off and the wrong weigh (pun intended). This was with a 3 part line, so if my math is correct it was under reading by about 12%.

Thinking back, this accounts to the many times I have picked things that weighed less then I was told, they didn't really but my CS system was reading low, not good, if anything I want it reading high.

The good thing is the unit is easily resettable, all it takes is picking a load of a known weight, and pushing a few buttons. It has been over 4 years since I put this unit in operation, without doing a re calibration, my bad it turns out. My junkyard neighbor has a big electric motor with a built in lifting eye, it probably weighs 1500 to 2000 lbs, I plan to borrow it and run it over to the scrap dealer along with the winters worth of beer cans and get a good accurate weigh in. Then I'll make a note of the weight and after re-setting the CS I'll put the motor back where I got it from in his junkyard, right across the fence from my crane shed. So, future checks of it's accuracy will be real quick and easy. ANY LMI can probably benefit from an occasional re-calibration, my faith in the CS is still high as is my customer satisfaction, they have great after the sale service reps, who as nicely as possible called me a dumb [pick a different word] for not checking it on at least a semi annual basis!
 
That's crazy! The last time I rented a crane was to make picks at 150 ft radius. I was talking via radio with the CO about the weight. The first pick I thought was 1200 hundred lbs......he said 3200...... I came down......we then picked it up with our toro mini loader....off the ground. Our dingo would never lift 3200! He said he thought the lmi had seemed way off. CO said he would take it to get recalibrated. I'm glad you brought that up CG :)
