Pully/Pocket wheel for Lifting chains...
(OP)
Hello, I'm just wondering, is there such thing as an Idler wheel/sprocket/gear thing for a lifting chain?
Similar to these: http://www.pewagchain.com/Products/Forderketten/He...
I've talked to these guys about their sprocket, but they're saying I have to use their chains, because their chains are calibrated, and it cannot be use with lifting chain because the tolerance is too high...
I'm basically trying pull a load at 90/360 degree, similar to a pulley, the "rope" has to be a lifting chain..

It needs to match the geometry of the chain fairly well.
I can't remember seeing any wildcats for sale separately.

if it is this
what you're seeking: It can be manuf. as per your spec (LxW, power transmission or fixation feature, etc.). This is a sample, used for a round link lifting chain.
Pls. contact the supplier of your chain and have them make you an offer or else point you towards a suitable manufacturer.
However, technically: Yes, the chain needs to be of good = sufficient quality, calibrated and calculated to suit the requirements during movement. If the chain is fixed at both ends, a take-up feature needs to be included into the system.

Here's my quick sketch..

does anyone see anything wrong with using the lifting chains this way? the pocketwheels are free spinning
because from my research, these wildcat/pocketwheels are ment to be pull like a hoist, and in my system, they're just idler wheel..

If you'd prefer to work with stuff that's been standardized and is available from many manufacturers, consider roller chain. Do respect the load ratings, of course.

I went with lifting chain because of its heavy duty nature & there are some studies with numbers on temperature effects on it's WLL.
Also, it was specified by the customer so I'm stuck..
Does anyone see any problem with this design to be used as the idler?
