I am attaching the new calculations done for the RICH winch load, the load calculation with the stiffening frame is included (page 274). In addition I have attached the BTHLD you did with us last time and the drawings for the stiffening tool which has the lifting
connections. The new distance between the swivels is 75".<br>
