trolley hoist wheels
(OP)
I am looking for a set of wheels for a trolley hoist. The hoist will be supporting a 2000lb capaicty winch with a 700 lb load (not a huge load). I was looking for the most reliable type of wheel, ie. angled wheels on angle iron, dual (upper and lower) wheels on an i-beam etc. Advice from anyone with experience in this field would be much appreciated. Thank you.






RE: trolley hoist wheels
There are two types of wheel configurations, one for "flat" running on W shapes and one is for "beveled" use on S shapes. Whenever possible I use S shapes for trolleys, the wheels seem to stay centered better. On W shapes the trolley will wander around a bit.
This is a very inexpensive trolley:

If this is for VERY frequent use you might look for hardened running surfaces, but I can't see a one ton unit requiring that.

OSHA also requires that even a 1-Ton hoist be so labelled and tested.
McMaster-Carr has some info & several manual trolleys, pages 1403-1404:

E.g.:
- Your concern about trolley durability suggests that the hoist must not only lift and lower a load, but carry it some distance, and the operation will be repeated many times. You might therefore want a powered trolley in consideration of speed and operator fatigue.
- If you already bought a wire rope hoist, you need a powered trolley anyway, because tugging a w/r hoist to move the trolley does bad things to the wire.

I have made drawings of a small number of cranes. I am too precise and therefore too slow to do it profitably, even at a modest wage, so I don't get to do it anymore. Which is my odd way of saying that the small crane business is pretty competitive, and homebrewing won't save you much in the long run, even if nothing goes wrong.

This company has some lightweight, easy-to-set-up 'work station bridge cranes' as well as gantry cranes which may be useful outdoors: http://www.spanco.com/
I prefer the 'flat rolling' wheels on patent rail: h

Crane manufacturers already have designs, you just give the size of layout, capacity, etc.
Your terminology confused everyone -- the 12 foot span is the bridge beam which will carry the hoist on an underslung trolley. The bridge beam rides on 2 end trucks which can be either underslung or toprunning on the runway beams.
