phase and 644 ft-lbs of torque for the same 500 pound evenly loaded TS-04 ((

trated in Figure 26) . The graph in Figure 24 shows the torque requirements to lift the same 500
pound total load on the TS-04 at the final push phase is about 20% less than that of the 50 inch
tire at the higher load second pull phase! The length of the device makes a substantial difference,
as well as the total weight.
