Re: Ice removal device

I haven't done any calcs on the 2" tube yet. I would guess the tension on both straps together would be half or a little less than half of the intended load. +or- 1/4 of the intended load on each of the ratchet straps. Looking at it now it does look a little weak on the main mast just below the bottom of the 45 degree brace. Making the brace longer so that the bottom of it makes contact right at the receiver would take care of this weak spot, but it would make me need to lengthen the top 2'-3" boom to about 3' long to clear the ice block which complicates things... The shorter lever in this case is better I think.

I could add an eye under the end of the boom tip that would make using a snatch block easy. This would double the capacity of the winch (but would not do anything for the capacity of the structure).

I used this snatch block theory on the elevator in my barn. It is a 12' wide by 8' deep flatbed elevator that I use to pull snowmobiles to the second floor. I use a 4000 pound capacity Warn 120 volt winch and have a snatch block to "double" the capacity/safety factor. It is slow but it lifts two Polaris 500's (at the same time) 13' from one floor to the other in 2 1/2 minutes.

For all of you Elevator inspectors out there it is not really an elevator. I call it "a vertical reciprocating conveyor".
