As nicely stated by N2MG, the gin pole "has to support the entire
weight of the load, plus the pull force."

For a standard gin pole, with only one pulley at the top,
lifting a 300 pound load, the gin pole must support
600 pounds.

The more pulleys you add to reduce the pull force, the less
load on the gin pole, but it can obviously never be less
than the weight of the load.
