how much for a whole set of cranesmart system? I do not think is the cost-competitive solutions.Your external cable running down the boom does two things: it keeps the LMI informed as to how much stick you have run out, and it also tells the LMI that you are attempting (or not) to two block your load line. A load sensor in the base of the boom senses the weight, actually the pressure, and combined with how many feet of boom and the angle, converts that into how much load you're picking.
I had two Terex boom trucks with this system, and when you snag that cable on a branch, and do not rewind it properly onto the takeup reel, you can be ALL screwed up! My current Manitex 22101S, bought used, had the factory LMI inoperative. I got it for 4 K cheaper, and then went out and bought a CraneSmart load cell and ATB. Both are wireless, so I was able to do totally away with the original system. The load cell read directly, a much simpler way to go. I make a pick, after I look and see how much boom I have run out(no digital readout, I just look at the boom markings, A,B,C etc), at the boom angle (though that is a CraneSmart option, wireless boom angle display on the same screen as the other info) look at my load chart if need be, and proceed. I love it, it is super accurate and I NEVER have to worry about snagging that damn cable anymore. Expensive, but worth it. Great after the sale service also BTW.
