These have actual working grease fittings, so they wont 'gall' the axles when pulling heavy loads. I'm using a 50-foot synthetic line on these to prevent the 'cable-pattern-burn' that happens with steel cable over pullys, which will damage synthetic rope after you use steel cable on these. I'm pulling the synthetic rope over these fine pully blocks, and pull the end with chain or cable . I love these monsters!
I got this today and by noon I was using them at 100+% of there rated load.
Wow, is this thing a powerhouse! I've used it to pull down trees & clear property with my winch, I broke a 30k lb capacity snatch strap while this pulley block is completely unscathed. It just keeps working flawlessly. I am very impressed! This was money well spent.
I love how easy this single pulley/snatch block is to use even with gloves on. Very well built rolls well even in freezing conditions / wet conditions. Has a very nice durable finish large circlip and greaseable bearing with fitting. Would recommend for professional or private use.
Got this for pulling my Silverado 2500 Duramax out if it ever got stuck and luckily haven't used it for that but have used for many other things from pulling an engine out of a boat and putting the new one in to loading disabled vehicles on trailers. This has worked with both synthetic and steel cable great.
