Once the rails and cylinder are installed... and the field wiring is done, a sheave (in layman's terms, a pully) is attached to the top of the cylinder.
Then the cables are run from the top of the rail - down under the cylinder - up and over the top of the cylinder sheave - and back down to deadend at the cylinder base. This is a time-tested method of hoisting the elevator. When the cylinder moves up 1', the Elevette will move 2'.
Guides are attached to the wall so that the piston head will remain plumb as it rises.
