Skid steers with forks are a bomb alright. A bomb waiting to happen that is. I had a guy with a skid steer about the same size as the one I have drop a 2500 lb pallet of ceramic tile by standing the skid steer on its nose one time He was unloading it from the upper deck of our step deck trailer when it happened. I told him the pallet was too heavy but he could lift it with no problem it was only when he lowered it when the problem occurred. What he should have done was to let the pallet rub against the side of the trailer while lowering it but he just backed up and started to let it down once he was at the critical point he found his self looking straight down.
I can carry an empty 20 ft container with my backhoe, but the one coming in is packed floor to ceiling front to back and probably has upwards of 15k of stuff packed in it.
You are correct about pulling it off side ways by turning it and cribbing up under one end And I have enough 6x6 by 4 ft blocks to block up a house. A lot is going to depend on the attitude of the driver when he arrives
