You're calculating it backwards. The slope is the angle of the ramp to level ground, and is usually about 10° to 20° for trailer ramps. The 50° was just an example for winching a truck up a steep, muddy slope.
Total weight = 3400
Winch pull = 10*3400/60 = 567
Ground factor = (pavement) 3400 * 4% = 136
Winch load = 567 + 136 = 703
Total weight = 3400
Winch pull = 20*3400/60 = 1134
Ground factor = (pavement) 3400 * 4% = 136
Winch load = 1134 + 136 = 1270
