I am going to start putting up bins for other farmers. I need to buy 6 tripod jacks and 1 roof jack. Any suggestions where to buy new or used would be appreciated. I live in central PA
Re: bin jacks
Here are some ideas from the web:
One doesn't hear of them being for sale very often. They are not that hard to build. There are several descriptions of them on the web. Search on some of these topics:
grain bin jacks
grain bin jacks manual
The bin jacks are mostly tripods. The roof jack I'm familiar with was two box irons, one insude the other (maybe pipe would work) with a X structure on top and bottom. A cable, pulley and winch arrangement to lift the center.
