gin pole

noun, originally and chiefly U.S., a pole, beam, etc., used for hoisting, typically fitted with a rope and pulley at one end and held steady at an angle by ropes (“gin, n.1.” OED)

“It goes two- three hundred feet high, down to the gin pole. So these big logs, they’re hooked at one end and when that thing takes off, the big cables, everything comes flying up in the air.”

“Everything goes by whistle ’cause nobody can see nobody, eh. And get down to the gin poles … the big engines down there on big bobsleds. And everything else was done by whistle ’cause you can’t see in the bush.”
