Hello! We installed a liftgate with engine and it worked well for a few days ... But now I start to lock up every so often when I want to open it. From what I could see, the frame is locked, above. The striking thing is that it doesn't always do it. All you notice is that it goes up crooked. Will that? How do I level it? Thanks in advance

Hello friend, first check the mechanical state of the gears, the clearance of the slides, the end and start sensors, lubricate the moving parts this is essential.

greetings toleto, if the gate goes up crooked it is normal to lock, maybe the counterweights or medium of tension is out of adjustment and requires calibration ,,, that calibration must be done by someone with experience, since if there are springs they generate enough force to break any bone in the body due to levers and tension generated, risk of death or serious injury

I get the impression that one of the cable ties of the counterweight cable was loose or not very firm, in which case you should check the length and tension of both cables that must be equal, you should also check that both counterweights are also equal, you must also verify the lubrication and the bearings of the rail remain running without obstacles or obstacles,
