I bought 2 of them. And man they work awesome. My company install wearhouse equipment, in and around the buildings here in south Florida for 25 years now. God I feel so old when I say that. Lol for the first 20 years I just man handled everything thinking I was still 25. Then I lifted something I shouldn't have. Crushed my l3 and l4 and It paralyzed my left leg from the knee down. After surgery and a long recovery I realized I needed a easier and safer way to install my equipment. I bought 2 600 lbs to see if they were any good and if they would do the heavy lifting with my forklifts. The things I have lifted and moved around just amazed me. After a few days of showing my guys how I wanted safety procedures Implemented while using this equipment. I bought 1 more 600 lbs and 3, 1000 lbs and want to buy 3, 4000 lbs. One for each of my trucks. My guys now fight over who's trucks the magnetics belong in. Really makes are job so much easier. If you work with metal and steel I absolutely recommend the magnetic lifts.
