Can I have the 182 and 282 close to each other. But, out of the range of the boom. Will the magnets attract each other?? Or do I have to have them a safe distance apart? If so, what is that distance. My space is limited, I would guess maybe a foot apart is ample. Thanks.
I have a 182 Magnetic Crane!!! This is an Electro-Magnetic crane!!! The magnet doesn't work unless you have it turned on!!! The magnets are not very strong!!! It is very unlikley the magnets would attract each other unless the booms were positioned so the magnets were right next to each other!!! If the magnets are more than an inch from each other you should not have any problems!!!
Cool, thank you very much. I will position them accordingly.
How do you wire up a 282 crane?? It has 2 attachment nuts underneath the controller. Do those go to transformer?? Which one goes to ground? Man, I wish I have the instructions. Thanks.
Tip for users of postwar era model 282 Portal Gantry cranes:
I have replaced several magnets over the years, and found that some of them seemed to require more voltage than others. (I don't know, but I suspect that some of the currently available "replacements" are actually designed for the 18 volts put out by modern TMCC hookups.) In any event, when run at about 14 volts, these electro-magnets have insufficient attractive strength. If run at higher voltages the magnets work fine but the motor runs too fast; i.e., the boom swings far too rapidly.
I tried Bob "lionelsoni" Nelson's trick of wiring a few diodes in series with the motor (only) in order to slow down the motors while keeping the electro-magnet nicely powered. Great improvement!
The only caveat is that you must leave the voltage to the motor high enough for the clutch mechanism to operate with sufficient "oomph" to engage-and-hold properly. A little experimention may be required to find the optimum number of diodes to use. (I used three in each direction, for six total.)

The link below may help a little. Most of the time it doesn't matter which wire you hook up from the transformer to the 282-200 controller. As a general rule, one of the two taps on an accessory and/or controller may be insulated from its metal body by a little fiber (or rubber) washer -- sometimes two of them, or a fiber insert. The "hot" wire should go to the insulated one. The "common" wire should go to the uninsulated one. This "convention" needs to be adhered to in "common ground" wiring schemes, for sure.
The tricky parts of the 282 are the connections of the five wire cable at the controller end and again at the accessory end. If these are right, the controller does the rest.
It may take some practice to master the coordination of the boom swing and the up-and-down motion of the magnet. Learn to do it smoothly and you will likely amaze your friends, because at first they won't be able to do it without overshooting. Don't leave the magnet powered-on any longer than necessary, as they will overheat and burn out.

Ok, thank you very much. I will be using a Z transformer for my 182 and 282 cranes, so voltage is not a problem. I ahve about 24 volts to play with. Thanks.
At 14 volts my 182 works great. Magnet not as strong but does the job. Thanks.
My 282, I am not sure if it is a 282 or 282R. My 282 has a silver magnet housing and gray smoke stack, but does not say 282R on the cab. I heard that all 282R have a silver magnet housing. And that both could have either a black or gray smoke stack. I do not have a box, so I am not sure if it is a 282 or 282R. Anyone know how to check this? Maybe the cab was replace with another. What are the motor differences between the two? I heard they are mechanically different. Oh yeah, and I am trying to wire this up. There are 2 attachment nuts on the bottom of the controller, which one goes to ground/and which goes to power? I will attach this to a Z transformer. So i would guess one wire goes to A and one to U for ground. I wonder what the typical volts needed to operate this 282? Thanks.
