Today at work there wasnt much to do so when my super seen me standing around he told me to get in the pettibone (big @$$ forklift) and bring the other crew some rebar. When I got to the rebar stockpile I was rather disapointed to see a trailer in front of it. I told that to my boss and he said "Just get the damn steel" Anyway to get the 20ft pieces of rebar over the trailer I had to extent the boom way out and way high. As I was backing up and to the right I realized it was leaning at more than a safe level. "This is scary" I thought. About this time is when the left rear tire blew out. That tire also happened to be the outside down hill tire. Over I went onto cab side. This story gets better.. keep reading. Luckily the boom was far enough out so it hit the ground before the cab did. However on impact, the seat tore away from the floor and at that point the seatbelt served no real purpose. I was in a semi-normal frame of mind so i figured first things first, turn of the engine. It kept running. 2nd, try and get out of the machine. That was also a no-go since the door was on the ground and the side window would only open about 4 inches cause of a tiny pebble I could actually see in the window runner. I was tempted to kick out the front window but that was also impossible since the seat was right in front of it and I had no where to put it. I also kinda figured the boss wouldnt like me kicking out the windshield. So I was stuck till someone found me. Help was a lot longer coming than I thought since all this happened out of site. It was only brought to the attn. of the others when my boss came to see why I was taking so long. All of a sudden there were 10 people to my aid. The pesky pebble was removed and I climbed out. Now since the motor was still running I was told to disconnect the battery but the second I opened the battery box, it fell out and went thru the side window, glanced off the seat and right thru the windshield I didnt want to kick out. Im ok and I didnt get fired. I will post pics as soon as their developed.
