One of our good customers has a 157’ Trinity built in 2006 with a Marquip passerelle. The passerelle had some basic service problems – mainly the tilt cylinder was leaking down and the main extension cylinder would not bring the passerelle back in without a full tilt up. This is an indication of cylinder by-pass. The vessel was hauled in our yard so the removal of the passerelle was relatively simple since we were not hanging over the water. Also, fortunately this Marquip passerelle could be removed without removing the main base or pivot table. This greatly simplifies the process.
Once the passerelle was on the bench, we could remove the extension to gain access to the cylinder. A simple rebuild and extensive testing for by-pass confirmed all was well.
Reinstallation and testing went smoothly. Another straight forward job on a Marquip passerelle.
