These clamp-on pallet forks were straining with an 1800 lbs even though they’re rated at 4000 lbs. Not only were they straining with a lesser load, but they bounced as if they were made with spring steel. Overall, this product caused me to spill a pallet full of $9000 flooring. I’ve been driving forklifts and tractors since I was a young kid, so it should have been easy, but no matter how easy and slow I went with these forks, it bounced profusely. Vevor removed my first review and decided to make me 3 bogus offers that doesn’t begin to cover the loss in flooring. Two partial refund offers and then one full refund was offered. They won’t even let me upload photos! Stay away!
