Hi there. 3 of these jacks work great to lift 40' long stick built walls with only two people but I don't know if they could handle the weight of a fully assembled bent. Additionally, the ones that I use can at most only lift a 12' tall wall to a near verticle position. 2x4 "pike poles" take it from there. Also I would think that you might have trouble finding enough good attachment points on your bents so that the jack itself doesn't get snagged up in your frame once the action starts. Hope this helps.
