We've run into stuff like that with customers using our Sonoran MicroBearing cables(which are heavy), and it usually works out well if you use cable-ties to fasten the cables to the rack/stand legs. This holds the cable to the rack, and in a good position(hopefully) to not interfere with any normal operation of your spring supported stand.
Actually, it sounds almost like a LP12 tonearm cable-dressing situation, and the cable needs to be securely fastened to the stationary part of the stand, while allowing a certain amount of "free-play" in the cable that leads to the equipment, so that it doesn't interfere with the spring suspension movement of the equipment platform. FWIW, if you get this right on a Linn LP12, then it sounds good, and if you don't, it doesn't. It could have similar effects on your platform.
