Terry H Posted December 20, 2019 Share Posted December 20, 2019 (edited) Just got an older Treasure Chest Crane, and the Bridge keeps jumping off the track when it travels form left yo right. It seems that the rear drive wheel gets more traction than the front drive wheel, which golphers the bridge and it jumps off the track. Any suggestions for fixing it?

gumball guy Posted December 21, 2019 Share Posted December 21, 2019 Are the bars that the bridge travels on bent or loose? Sometimes even a slight wide/tight spot can cause it to jump off. If the whole set up seems loose then tighten the screws at each end of the gantry. Once the screws are tight and you can see a wide or tight spot between the two rails then gently squeeze or pull it in or to straighten it out.
