Someone (Walthers or Model Railroader) had an on-line video demonstration of this thing a couple of years ago. The container has to be turned 90 degrees to get it out between the legs. Not realistic at all, but you can't expect too much from a novelty item. You supposedly had to have metal plates in the top of the containers or it couldn't pick them up because it used magnetism.
There may be more than one version of this puppy, too, so the one the OP has may not be the same as the one in the video.
One of our club members bought the 'non-powered' version - looks very nice. But, it appears that it can only handle 20' containers. Does the powered on have the same limitation?

I think Heljan made a marketing blunder with this. Obviously, if it's being discounted this deeply at Walthers, it's not a big seller and they've got more of them on their shelves than they feel comfortable with.
This is, according to their ads and manuals (available on-line) a DCC device. But, the system is designed to be stand-alone, so they basically provide a complete DCC system with it. That's nice for people who don't have DCC, but it bumps the price way up for others who already have DCC. It has it's own control unit, which probably looks like a throttle/base station combination. When this came out, I looked at the manuals and it looked to me like you could actually run this from any DCC throttle. If so, though, then they could have reduced the base price by a hundred dollars or so, and sold their control unit separately.
Kind of a neat unit, particularly in the videos. It looks like they're using the Faller Car System to provide "ambience" around the unit. It would be interesting to see that really used in an integrated fashion - bringing in trucks for loading/unloading.

Type "heljan container crane" into Google and there will be several pages of discussion about this product.
Sorry, I can't offer any more help than that. At a price of around $750 I'll sure never own one.
