VEVOR Black Industrial Machinery Mover Skate Dolly, 13,200 LBS/6T, Carbon Steel, 4 PU Wheels, 360 Rotation Non-Slip Cap

Good quality.

VERY UNSTABLE - Wheels will easily spin, but they constantly get stuck in an unstable position. Easily tips even when the load is centered. Be very careful if you do try using these. Heavy Duty.

I just got this today and it looks like it will handle the machines I am moving in my shop. I was disappointed that one of the nuts for the handle was not the same as the others and had the wrong threads, but I was able to find one in the shop, so it was a minor annoyance. The handle comes in two pieces that attach with metal straps rather than being one piece and that is worrisome. It is rated at 3 tons so I would expect a beefier handle. I have a feeling I will be making a new handle out of better material.

THIS THING MOVES TRAILERS AND HEAVY EQUIPMENT LIKE AIR. GREAT PURCHASE.

I was really surprised that this helped move a VERY heavy safe into the garage. My only complaint is it turns on its own, wish the bar/handle locked in place. Otherwise it's great

It's substantial and good quality but it’s missing a piece.

These devices are utterly ineffective. Be prepared for your equipment to plummet. The wheel pivots are too close together, failing to establish a stable triangle formation beyond the load. When the wheels turn, it's inevitable that everything will topple. I even tried using four of them with just half the recommended load, and they all ended up bending!What's frustrating is that their product images cleverly suggest a wider triangle configuration outside the turntable, giving the false impression of stability. However, these contraptions do nothing but tip over. I can't fathom how anyone could design, test, and decide to market these.The handle is positioned in such a way that pulling it causes the wheels to move behind the center of gravity, resulting in inevitable tipping. They are nothing but useless junk. Do not waste your hard-earned money. I regretfully spent $400 on four of these, and they're essentially just scrap metal now. This is coming from someone who rarely writes reviews, if that tells you anything.

If you have to move anything heavy, these are a must have for smooth floors. Moved a 19ton bus with 4 of these around my shop.
