Sorry for rambling. We did a rental job last Saturday. Lifting a 40,000# culvert at 80' radius. They had cut the street in half to lay the culvert pipe in. Job took 102,000# of counterweights. We hauled them in on a tri axle and a tandem. Backed the crane up to the ditch and backed the first c/w trailer up to the front bumper of the crane. The first c/w lift was 26,000#. The three pieces are bolted together. It is possible to break them into three lifts but not practical. With zero c/w hanging we all but maxed out to lift the 26,000# onto the deck but, we could. The next c/w bundle was on the front of the trailer and was 35,000# at a 60' radius. We were only good for 25,000# with 26,000# hanging. So, we lift the two thing slabs off (10,000#) and set on the back of the trailer. Set the 26,000# slabs on the deck and we could then stack the two thin weights on the 26,000# giving us 36,000# of c/w. We could then lift the remaining 25,000# on the front of the trailer. Grabbed them and set them on the back of the trailer. Set the 36,000# on the deck and grab the two thing slabs and set them on the 25,000# which is on the back of the trailer, then stacked them on the 25,000# setting on the deck. Moved the tri axle out and backed the tandem trailer in with the two 21,000# cheek weights. Had to lift the 60,000# before I could reach the 21,000 cheek weight on the front of the trailer. Set that one on the back of the trailer, set the 60,000# on the deck and finished stacking the two wing weights. Sheesh...dizzy yet? After 2 hours setting the crane up, we set the culvert in 10 minutes. Then break everything back down. I hope the next job allows us to back the trailers beside the crane.
