A hoist for transferring the ends of power lines between supports at different locations including a pair of hoist mechanisms each having a respective tension line receiving drum and which are simultaneously operable with a single crank arm. Each drum has a respective ratchet mechanism that can be selectively set such that upon pivotable movement of the single crank arm between a first and second positions the ratchet mechanisms (i) simultaneously rotate both the drums in a take up direction for simultaneously winding said tensions lines onto the drums, (ii) simultaneously enable rotation of the drums in a release direction for simultaneously unwinding the tensions lines from the drums, or (iii) rotate one drum in a take-up direction for winding the respective tension line on the one drum while simultaneously enabling rotating the other drum in a release direction for unwinding the tension line from the other drum.
