Hello guys, I have problems with my Zippo 2 columns lifting platform 1511 (2 columns 1 motor) First I had problems with the 2 contact switches, which are operated via the “control cable “. After further investigations I could find that on the side without motor the rope completely unmounted and the pulley (as well as small rubber parts) lay on the ground on the motor side also small rubber parts. There I noticed that above the support nut, quasi on the safety nut a metal hanger that has a remarkable amount of play and sits crooked ! Here’s a picture of it: http://www.bilder-upload.eu/thumb/f1a8ec-1413226950.jpg Now I don’t know what this metal hanger is for and how to replace the rubber parts. On the Internet I can read some of the damping strips, sliding rails, sliding piece, rubber carrier nut strip…..usw… but don’t know enough about it. Can someone help me further ??? I would be very pleased as the lifting platform again is needed.
