Never trust a chain - I worked on a horizontal drilling rig in 2006 using an American Direction Drill "Million 80" unit (read-huge) boring twin 4' diameter holes in solid rock . They were using a 1" high grade chain to hold the head unit onto the transport trailer to help keep it from sliding into the bore pit - by tying additional heavy equipment together like a dozer (buried) as well as a second excavator . I was the "wildcat" tending the drill rig , monitoring it and swinging drill stems on/off . Long story short - after the 14hr point (26hr day total) pulling the new pipe through the bore the chain failed . It backlashed fast enough I never saw it coming , just saw the whole rig jerk and jump into the air , woke up 25' or so away from where I was standing with the whole crew looking at me - holding their cell phones . I thought those a$$holes were taking pics - they were prepared to mass dial 911 - thought I was dead . Chain hit just below both knees , bent both joints backwards around 30* or more and tore out a lot of cartilage , tendon damage and left permanent imprint marks in the bones to match the chain links . Finished out the night's work and got the pipe pulled through - went home at 7am and to bed , really sore and feeling generally numb .
Spent nearly 4yrs off work , 14 months in therapy and 4 knee surgeries - I still work construction but pretty much only light duty work . Whole deal ruined my credit and screwed up my chances at retiring with any decent pension .
No one else will look out for you - this is your responsibility and definitely in your best interest . After all the broken fingers , drilled eyes (60 days off from a piece of lousy dirt) and scars and general joint damage I'm half crippled and wore out . Not a good way to enjoy you're "senior years" - I'll be lucky to ever be able to retire now...
