Before I put the 1400 lb counter weight on my National, my arse meter was telling me NO MORE, while the LMI was telling me go further. Now, it's the other way around, still feeling stable with the LMI buzzing..... best $3400.00 I ever spent, though a lot for what amounts to a big chunk of iron.
I had a job 2 days ago, reaching out 77' to the stack, and then setting them right in my face, 20' away. With a good crew, I'll take a second to explain how I need all the stick out to reach the stack, but now with the boom at 75 degrees and working so close, it's a bit touchy so bear with me. In other words working real close is harder then further away, obvious to us but not to the nail benders sometimes. One thing I don't do is constantly retract/extend, and I always try to get the furthest work out of the way first and hopefully when the last truss is set the boom is almost sucked in and I'm ready to hit the road!
