I know I've asked some rather bizarre and esoteric questions at Coasterbuzz. Here are some more.

I need to know how a Ferris wheel is controlled--how it's started, stopped, advanced, turned on and off (not the motor mechanisms on the actual wheel itself, but rather operator control). I need a description of the typical control panel and how to use it.
Of course I'm sure there are many different designs for Ferris wheel controls and their operation. I just need something typical, preferably from an older model that might have run, say, between the 's and 's. I'm guessing much of the basics of operation are fairly universal.
Please, and pre-emptively, thank you. :)
If we are talking what the typical Ferris Wheel that most people think of , that's the Eli #5 or #16 Wheel, or just a "Big Eli". Until recently these wheels had but two controls. They have a clutch and a brake. These are both hand controls, utilizing a rachet and pall locking mechanism that would lock the controls into position. The operator squeezes a release lever on the top of the control lever to move either one into the desired position. It takes a fair amount of skill to operate a cable drive Eli, especially the #16 wheel, so much so that a good Eli man was paid more than the average ride jockey.
I found this discription of how a #16 wheel is handled. It's the recollections of former Mountain Park employee Jay Ducharme during the last seasons of it's operation.
I was quite nervous when Roger Fortin trained me on the big wheel. I never considered myself good with math, and this ride required some on-the-fly computation. The wheel was powered by a small motor attached to an ingenious butterfly clutch system. The clutch had two curved shoes, much like old car brakes, that squeezed against a drum (like a tire rim). The drum engaged a steel cable (about 3/4 of an inch in diameter) that looped around the rim of the wheel. Along that one side, each sweep (the piece of steel that extends out from the central hub) had two flared angle irons at their ends, through which the cable passed. The operator stood in front of the clutch mechanism, next to a long hip-high lever. The lever had a squeeze-trigger that allowed it to move forward or back to engage or disengage the clutch and activate the brake. A push-button switch would send power to the motor.
All this is important to note because the ride operator, unlike with so many modern "automatic" rides, had complete control of the wheel and had to be constantly alert. All of the seats were numbered. So if two young kids sat in seat number 1, for example, I would have to mentally note their combined estimated weight. Then I would engage the clutch and swing them around to the top of the ride until seat 9 (directly opposite seat 1) was next to me. Then from the queue line, I'd try to find one large guest or two more small guests and ask them to sit in seat number 9. I'd have to do this to balance the wheel. Since the only thing turning the ride was a relatively thin cable running around one side of a steel rim and through a small clutch, an out-of-balance wheel would cause the cable to slip in the rim, and the wheel wouldn't be able to turn all the way around. It was especially bad if the ride was wet. Obviously, the ride could accept some variation. But if it was loaded it too heavily in one area, there was trouble.

As they came from Eli Bridge, there was no lock out. When a wheel was installed at a park ordinarily a power cut out switch was installed that had fuses/circuit breakers in it and had lockout capability. With the portables that had a industrial gasolene engine for power, I used to see the carns chain up both the clutch and brake levers when the ride was not in use, but often as not it was left sitting there with just the brake set.
Yes once the wheel was loaded you just engaged the clutch all the way and let her go, no deadman control in those days. I've seen operations where they had one person running two or more rides where the op would go off and leave a wheel running with a load on it and go load up another ride and start it up, and then the op would come back and start unloading the wheel. Never get away with that these days.
I got the chance to operate Strickers Eli on several occasions but the Clutch engaged as the brake was applied. You simply engaged it at different levels according to how fast you wanted it to turn. It took a fair bit of skill to slow it and stop it in proper position and some moderate skill just getting people in and out of it and most importantly. KEEPING IT BALANCED. Those cables in rubber lined cable tracks won't hold if its unbalanced and then you have a ROLL BACK!.
Everything done right and guest riding properly. There were never any problems. However, I still say, This is one of the most dangerous ride in existence. The newer hang under ones are much more stable. The eli type is not hard to dump someone forward or backward and expecially at loading time or by someone rocking the tub. They ain't that stable people. Pass the fulcrum and over she goes. Im surprised at how few accidents there really are.
Yeah, It was single lever with a hand clasp that had to be squeezed to get the lever to move. Forward was engaging the flywheel. Back toward you was brake. You pulled it to you to slow it and you started slowing it about where the car you wanted to load/unload was just past the top. By 3/4 down you were full brake and hopefully it stopped where you intended :) If it was a little short, You could just bump it forward a bit, but if you passed the platform that you had to raise to catch the car bottom, We'll you sent em around again! :)
Now what was really fun and hard for a 13 year old to do was operate the Herschell Kiddy coaster that my first year there didn't have the Pnumatics but the old heavy lever with the thumb button on top. Give em two laps. Ok, you set the brake to let it slide through the station at just the right speed to catch the chain easy the first time and full brake the second.
However if you didn't set it right. It would scream through the station and 3/4 up the hill and BAM the chain dogs would catch and the whole park would know it!. You had a workout on either of those rides.
Now the Scrambler and Tilt were fun to run as you had control at that time you could work the clutch on the tilt and get em sick. The scrambler at that time was Insane at full speed. Now it probably runs on about click five of what used to be 8.. You could also work the riders, Wanna go faster? YEAH!
I wonder what a "Ferris wheel" is called in BE.It's commonly called just "The big wheel" here in the UK, although I suspect most BE speakers would know what a "Ferris wheel" is.
