Excavator stuck in bottomless mud.
Easy to say it never should have been in there, but what a pleasure to watch someone with that kind of skill: there was one way to get it out, and he did exactly what he needed to do. Having watched other videos of excavators stuck in that type of mucky clay, this operator may not have been an extrication expert, but he eventually found a combination of maneuvers that got him out. The coarse rock mixture was a good idea, but better for him to have used an even coarser mix, or boulders of a small size. In Australia, where I am, I've seen them use a technique of laying a boulder path over a river, and then driving the excavator on top of it, in order to repair a railway bridge that had been flood damaged. It's all in knowing how to handle your machine skillfully and properly assessing the challenges the environment poses to operating it in certain conditions. Most B series cats are gems to operate. I will have to assume its a 322 or 325 as you seemed to have covered the numbers. As for the cat excavators we run or used to run 215 c,225 c,b,235b,245c,303c,307c,312b,c,322b,325b,345b .I have to say that they were or still are great machines. I don't recall ever being stuck and believe me we have mud here. I have owned or still own many of these machines and do believe I do know what I am talking about. It's always good when you can get yourself out. I have been stuck many times. Even in Cat D6 LGP. I worked on a job (in NYC) where they completely sunk a Komatsu 1000. They had to drive 120 foot sheeting around the entire worksite.(approx 200×300) Then bring in huge pumps to keep up with the water coming in from the East River. Then they bought in another Komatsu 1000 to dig up it's sister. The mechanics came in and disassembled it. A crane loaded it onto flatbeds, and they took it away. Belleview Hospital almost fell into the hole. We had to core drill 260 feet into the mantle every 3 feet along the hospital wall, and attach the hospital to the grouted drill shafts. See, it could always be worse. LOL There is a 15 story building there now. IUOE Local 15
