The elevator guys have been very busy and our elevator is waiting on parts, so they’ve just been doing half days. Today was the installation of most of the wiring and top of cab electronics. There will be another day of actually connecting the installed wires.
Here’s a shot of the elevator traveling cable. This goes from the elevator controller to the top of the cab, so it has to be hung in a big loop to allow the bottom end of it to move with the cab.
After some web searching Martin was able to find the manufacturers web page for this particular traveling cable. This one has 24 conductors and is manufactured by Shentai in Taiwan.
This printed circuit board is a bit of a surprise. The doors actually on the cab are called “Gate doors” and we’re getting automatic ones. We thought that these and the shaft doors were going to be manual.
This is Nationwide Lifts’ controller for those automatic doors.
This printed circuit board is where the traveling cable hooks to all the stuff mounted on the cab. The traveling cable is terminated into the terminal blocks at the top and only 20 of the 24 conductors seem to be used. Martin will ask the elevator guys about this when they’re up next.
All the other terminal blocks hook up to things like the top of cab lights, the gate switches on each of the gate doors, and so on.
This stepper motor drivers (we have 2) are what actually control the gate door stepper motors. They are controlled by the Nationwide Lifts controller.
One more bit of safety gear mounted to the cab - the slack cable detector. There one of these on each side. The little black wheel at the right touches the elevator cable and is pushed in. If the cable goes slack the wheel pops out and the elevator controller activates the emergency brakes.
If you look at the printed circuit board at the top that the traveling cable is terminated to, you can see a terminal block at the middle right labeled “slack”. That’s where this is connected.
