Rick:
The motor shaft is 1/2 inch diameter. You mistook the size of the keyway for the shaft size. The motor develops 1/9 HP which when geared down from it's approximate motor speed of 1600 rpm to the 10 rpm out of the gearbox easily develops the 500 inch-pounds of torque. It's a very hefty motor and gearbox. Nominal current draw by the nameplate is 3.6 amps. I put my clamp-on ammeter on it while raising the tower and it drew just 3.0 amps. So the motor is not overtaxed.
