Exactly what i thought Yuri them door's do get some hammer i had to wire some limit switches on a vessel for up & down the one in particular was warped & bent out of shape by about 140cm the hinge's had to be replaced it took some doing i was not doing the metal work i was one of the electrician's on the control gear for the door's

At first sight I took it for a hull damage but
at second sight I realized that it was a very rusted ramp.
