Platform lift trailer
The platform lowers hydraulically to lay on the ground, you load the safe, secure it, then use the hydraulics to lift it up to regular height.
A friend and I moved a 4000 lb safe he bought (TRTL60) with one and a pallet jack, come-a-long, some rope and pieces of 2x4 and 4x4, and a boat load of 10,000 ratchet straps from Sams club.
We rented it from the local rental place. They use it to haul around scissor lifts. It cost us ?$100 for 24 hours.
10,000 lb ratchet strap to hold the safe onto the pallet jack. Move very slowly and think ahead.
Come-a-long to pull it up on the deck (attach to trailer and pallet jack).
We used a few of
these across the top. Then run a ratchet strap (
from here) from one back corner of the trailer around the front of the safe, through the sling and back to the other back corner. Do the same from one front corner, through the sling and to the other front corner. Do the same thing from back corner, around the opposite side of the safe and back to the same side front corner and vice versa.
Four ratchet straps, two slings, and it isn't going anywhere.
If you want to be even more secure, you can run some stacked 2x4s or 4x4s from the front of the safe at the bottom to the front of the trailer and then run a ratchet strap around from the front of the trailer, around the bottom of the safe and back the the front again. The wood keeps it from shifting forward, the strap from shifting backwards.
We actually left the pallet jack under the safe on the trailer- jacked it up, put some 4x4s underneath around the jack, and then strapped it on.
There are different trailer designs out there, but 2500 lbs should be easy for just about any of them.
We called a rigging company for a quote and they were in the many thousands ?$3K plus? (I don't know how serious they were, they were going to use a crane on each end of the move) to move it 70 miles. We did it for around $200 (already had the lifting slings and a bunch of the ratchet straps). Remember, momentum is your enemy. If something starts to tip, don't be in its way, and don't try to stop it, just watch it go.
