Winches: Ratios and Reality
When comparing winches, itís important to understand how input and output interface. The winch handle is a rotary lever that is the first stage of power amplification. The ratio of drum radius-to-handle length is the first force multiplier. An 8-inch handle and a 2-inch radius drum, therefore, deliver a 4-to-1 boost in pulling power and a 4-to-1 decrease in line-hauling speed.
