Sort of. It held 120+ safe deposit boxes at a local credit union branch office. It spent a couple weeks under plastic and covered in pallets at that worksite setting in the parking lot without issue. I have it up off the ground on some 6x6 treated timbers, but the same overall arrangement. One benefit to being a commercial safe, all the parts are still available for it. Everything works smooth like new, but should something occur it can be repaired without a huge expense.
When I arrived at the place doing the hauling today, it was apparent it had slipped the owner's mind. When he was considering what to do, another fella stepped out and said "don't let him BS ya any, whatever ya need done we can do. What do ya need?". Owner said "12,000lbs safe hauled 40 miles." and the other fella replied "No problem, point me in the right direction, lets go!". The boss was fumbling to get the words out "uh, that's what my rollbacks are rated at." and shouted for one of the other guys that was washing one of the big trucks. Told him "take the new rig down and see if you can load this guy's safe".
I went on to the site ahead of him as I had a meeting there with other contractors and the owner. The driver showed up in a new F650 rollback a bit later and brought along a helper.
I went out and told them if they could turn it around with the safe doors on the driver's side of their truck it would make unloading a bit better at the destination. They had high confidence at this point and said "no problem".
I went back to the meeting but could see what was going on and they had no issues turning it around. My meeting finished and I went back over to watch and/or assist. I snapped a quick pic of them rigging it up to start the load.
After rigging it up, they winched it up tight to the edge of the bed, but it wouldn't come off the ground to start up the bed (only needed to come up about a half inch to start onto the bed). The guy operating the truck kept the winch pulled tight and tried working the hydraulic extension on the bed to get it to pop up and start up the ramp. All that did was push and drag the truck about 3 feet in each direction, the safe never moved.
As they were stopping to reassess the situation, I got that prybar that was recommended earlier in this thread (THANK YOU) out of my truck and said "maybe this will help". We found a place along the back of the safe it would fit under it. With one of us hanging on the prybar, and the other two pushing on the safe as if trying to knock it over, we were able to get bits of this and that under it enough to get it teetering lengthwise a little bit. Just enough to create a half inch gap under the end of it. We picked up a couple old pieces of 1/2" rebar that was laying around and stuck one end under the leading edge of the safe, and the other end on top of the truck bed. At that point, he winched it up tight again and it bent the rebar as it pulled up to the edge of the bed, but still wouldn't pull up and onto the bed. He started working the hydraulics on the bed again, shoving the truck around like it was nothing. The driver said "I don't think this is going to work, we're going to need..." and just then the safe popped over the edge of the bed. Guy hit the winch and pulled it up the bed. Driver said "That's why I brought him along, he's persistent about these things and gets it done!"
Once up on the truck, the tires sat REALLY low. I'd say there was a good 8" contact patch. When it was loaded, it seemed like it was centered pretty good, but when you stepped back away from it, you could see the entire truck leaning to the right. Turned out the safe was about 3" off center towards the passenger side of his truck. Driver said he could really feel the weight on left hand turns, and the best uphill speed was 55MPH on the interstate with a 70MPH limit. He also said it was the smoothest ride he ever had in that truck.
After getting to the farm, he backed up to the temporary pad I setup for it and tipped the bed, but couldn't tip it enough for it to slide down the bed. He had to pull forward some to get more tilt on the bed. After getting it to the back of the bed, the front of the truck was a couple inches off the ground and the bed hydraulics wouldn't tilt back up to get over the pad I'd made. I asked "do you think my tractor would give enough assist to get it up?" and he said "we can try" so I went to the barn and got it out. Switched from the grapple to my bucket, and when I got over by the truck, he told me to try pushing down on the front of his bed. I did, but all it did was lift the front of my tractor. I told him I only get about 1500lbs in downforce before the front comes up, but I can lift over 2000 so it might be best if I tried lifting at the rear. He agreed and I reposition. It took everything my tractor and his bed hydraulics had, but we got it back up so he could back over the pad. From there it was clear sailing. He set the edge of the safe on the timbers and pulled the bed out from under it with ease. Before dropping it fully, we put some pieces of rebar under one end so it wouldn't be setting tight on the timbers and be easier to get ahold of for the final move to the new building.
At this point I was able to get a couple other pics.
Ignore the leaning shed behind it, that will be coming out this month and replaced with a pavilion to cover everything. There are grapes beside that shed that is pulling it over, they are getting moved too...
