residential swing hardwares
for a project i need to specify hardware for a residential indoor swing. please guide me with regards to the kind of hardware i need to call out that would connect the swing to the structure
check out our whitepaper library.
how strong would you make it for your child? how heavy is the person that will use it? osha asks for a safety factor of 10 for lifting personnel.
richard a. cornelius, p.e.
build it for a child,no a group of kids.
a kid can bust a rock.if you design with this in mind a 400lb fat man will be no problem.
37ed, you got it right. my kids tested a tonka ready mix truck. they saw an ad that the tonka people drove a real truck off a cliff and threw the toy truck off, too. they threw their truck off a 60 ft. high bridge to the rock below. then were upset when the plastic truck broke.
go to a couple of "private' i.e. expensive, school playgrounds and measure the fittings. they will have a strength about 10-15 times what they need.
richard a. cornelius, p.e.
consider strength but don't ignore durability. from childhood experience--man, that's been a while--whatever you use needs to contain a bearing surface that's intended to be used in this or some similar application. don't just put the end link of a chain in a u-bolt no matter how big they are. sooner or later it will fail and by default, there will be someone in the swing when it does. get a connector with a bearing in it that's intended to allow motion with minimal friction and wear.
