Shoutout to the load chart for telling me my counterweight math was off by 2,800 lbs
I was about to swing a rooftop AC unit over a crew in Sacramento when a new guy pointed at the chart and asked if I counted the jib. Spent 20 minutes rechecking and turns out I had been guessing at counterweight deductions for a while now. Anyone got a trick for double checking that stuff fast on site?
The new guy saved your butt and probably a few others on that crew too. Nothing like getting called out by the rookie who just finished his cert class last month. Your counterweight math being off by 2,800 lbs is not a small oops, that is a "someone goes home in a box" kind of oops. Here is a trick that works for me: before you even look at the chart, write down every single piece of the lift on a notepad. Boom length, jib, block, rigging, load weight, and the counterweight you think you have. Then work the chart from the bottom up instead of top down. Forces you to actually see each deduction instead of skipping the ones you forgot about. Also keep a grease pencil right on the counterweight stack with the actual weights written on it so you are not relying on memory. Takes two minutes and beats spending twenty minutes rechecking after the fact.
