Drive assembly work, cable spool, 11/15/07
Work continues on assembling the modules of the Drive Assembly into one functioning unit. Not only are the modules being brought together, but the two electric motors and gearbox are being installed as well. In addition, the spool of cable that will bring the cars up and down the track will be brought up into the Machine Room via fork lift. At this point it is still a long way from “powering up” the new Drive.

The Source of Power
This motor — still dusty from its trip on the truck — along with the special gearbox, will be the source of power for the whole thing.
All the parts must fit perfectly, and it’s not easy!
Tools of the Trade
Hand-operated winches, like this little “come along,” and chains are indispensable tools in getting things moved and placed.
“Hey Leonard, it’s about time YOU got in one of these pictures!” That’s what they said anyway. So I consented to have my picture taken. What did they do? They focused on the guy popping up behind me like Kilroy!
You see the slot on the left-hand frame. There’s another directly opposite. As they bolt these two pieces together — slowly, carefully — there’ll be a dowel that fits in the double slot, guaranteeing an exact fit.
One of the many reasons for an exact fit everywhere is because the output shaft coupling from the Gearbox must connect precisely to the coupling on the Drive Shaft that turns the Bullwheels that move the Haul Cable and, thus, the two cars.
Eventually, these two parts dovetailed perfectly.
Now for the Cable!
The spool of cable weighs over a ton. There’s a thousand feet of cable. You can roll it, but that’s about all. It will make the fork lift trip up to the Machine Room, just the way the rest of the equipment has.
It’s in situations like these, where I deploy my telephoto zoom, bringing a higher level of interest and drama to the proceedings. The 4/3rds sensor on the Olympus E series of cameras means lighter weight and portability, obviating the necessity for a tripod or monopod — thank goodness!
The cable comes to rest on the Machine Room floor, where it will stay until near the end of the project, when 300 of the 1,000 feet will be used for each the Haul Cable and the Safety Cable that will connect the two cars.
This powder blue motor is on standby in case there is a malfunction with the regular Motor.
Coming Along Nicely
The Motor and Gearbox module is in place waiting for more tweaking. The last component of the Drive Assembly — the large Reversing Sheave — sits on the Machine Room floor on its side, waiting to be fit into the rest of the puzzle.
