I figured I start this thread because I've had a few but today took the cake. I'd like to hear of everybody's as well. I'm not talking about that car that cut you off and you smoked the tires moments but the real true pucker moment in your career. The one you will never forget. Here is mine. Today I had to deliver a 9K JLG 45' shooting boom forklift. The machine weight is roughly 24-25K. I took it to downtown where they are building a new hotel for the new Horseshoe Casino they just opened here. The site did have three entry points but they are raising beams into place with heavy cranes so two of them are blocked. The only entrance is down a gravel slope of about 2%. It rained here last night. The gravel was wet. I turned into the place to find another semi unloading windows in the entrance. Son of a beech! The customer meets me and says " We are going to have to unload here, you won't be able to get in." I was hesitant but said whatever. So, I set my tractor brakes, engage the PTO, throw a chock in front of my front drive. I begin to slid my wheels forward on the Landoll. Now mind you the JLG is backed on with the counter weight facing the cab of my truck, which is pointed downhill, on wet gravel. I balance my weight on the wagon and start to raise the deck when the truck starts sliding. Not just a ehh, it moved, but rather a holy f*#king **** this is bad news! My initial reaction was to reverse the process that started the forward momentum but didn't have time seeing how it was just about to jump the chock. I hopped into the cab and set the trailer brakes as it jumped the chock. The whole truck slid about a good ten feet. Had I not stopped it, it would have made news because people would have been hurt. Needless to say, I waited for the semi to unload his windows and proceeded to flat, and level ground to unload. I won't ever make that mistake again! What mistake you ask? The mistake of being impatient and rushing so I can get done and go home. Puckered me up so tight I won't crap for days. Here is a link of the same forklift I was referring to. http://www.jlg.com/en-US/Model.html...&ModelId=cd5d5b2f-b2df-4e3a-b431-1d6c64f3aee4 By the way, I wish every construction site looked like the one on the web page. I have yet to see a site all clean and open like that!
