rlf 3 #1 Posted November 19, 2017 Does anyone know the load capacity of the rear and mid quick attach brackets? I am considering using them to mount a sub-frame on which to attach a front end loader. Share this post Link to post Share on other sites
Ed Kennell 35,146 #2 Posted November 19, 2017 I have never seen the load capacity ratings you are looking for, but by measuring the cross sectional area of the weakest points and multiplying the area times 60,000PSI (tensile strength of mild steel), you can calculate the capacity of the brackets. Keep in mind this is where it will break. For a working load limit, use a safety factor of five. The mounting bolts may be the weak link. 4 1 Share this post Link to post Share on other sites
lynnmor 6,700 #3 Posted November 19, 2017 My Quik-Way sub frame was made to use the front and center attachment points and the rear of it was to straddle the axle housings. Mine is modified to clip in the rear attachment that is used for snow plow and tiller usage. I have worked it hard for twenty some years with no failures. 2 1 Share this post Link to post Share on other sites
rlf 3 #4 Posted November 24, 2017 Thanks. Looking at the task, it seemed that the Attach-amatics would be just as and stronger than bolts available or weakening the frame with holes. Time to start cutting and welding. Share this post Link to post Share on other sites
WNYPCRepair 1,875 #5 Posted November 25, 2017 I built my own, but it was copied from a Kwik-Way loader, I believe. @Snowmobileaddict would know better, I copied his build somewhat. Mine uses the mid point, and attaches around the rear axle with square U bolts Share this post Link to post Share on other sites
