I need to build an adjustable retainer like the attached picture. I can't find someone to supply a 6' section of 25# crane rail. All I can seem to find is 30' pieces. I was wondering if anyone had suggestions on an alternative to crane rail?
Perhaps stating the obvious, but have you looked hard enough?
Any facility that uses those, must have old rails lying around in abundance.
Of course, 25# is a very small section, you'll probably find bigger rails more easily.
The crude actual shape (and its problems with weld certifications and wheel fit on the upper surface) for a backyard rough-shaped bundle of flat bar are not recommended for a crane rail actually carrying loads.
It keeps a thin coil from falling over as the cart moves to the mandrel. The one shown is from the manufacturer (20 year old line). I agree I'd prefer to go to the manufacturer and ask for an improved design but management says we need to design something. First time it has happened but we had a thin coil fall over and and do some damage. I believe management jumped the gun on adding more keepers. Operator claims the keepers were in place but we don't think that is the case. Cart may have traveled to fast as well. I feel it comes down to discipline and making sure the set up is correct. Adding some reminder signs also. If anything adding something to verify the keepers are in place is a better route.
