I just took over this job 2 weeks ago. This has been wrote up multiple times by the inspector.
Too add fuel to the fire. I had a shorted brake coil on this unit. I called our companies part house and gave them the controller job number and told them I need a brake coil. She said no problem she has every thing she needs and will call me back once she locates what I need. I asked her to hold up what machine does the file indicate I have. She answered a Isis 2 German machine. I told her this was the wrong machines, they are a Torin ER6. She told me then is has been modded and she needs the new number that went along with the mod. This job is not that old, Tac50-03 controllers I figured no way this job has had a mod done. Turns out the machines were changed out shortly after the job was taken over on maintenance by billable repair. I called the repair supervisor and told him I needed the updated job number. Long story short, the job files were never updated. So I called Torin to get the part number for the coil. You cannot just change out the coil you have to change out the whole main brake, had to have a repair team to come hang the car and put hold backs on the ropes. I retract any previous statements saying anything good about MRLs and anything bad I said about hydros. Wow this has been fun, I made one hell of a splash in my first couple weeks on this new endeavor I've taken on.
In my experience mrl's are good, but when mechanical repairs are required will be a bummer just due to the nature of these units. The product we used was Macpuarsa and I must admit its a pretty good unit and mechanically a damn site better than a monospace. The only drawback from this type of unit is some manufacturers install the controller inside the shaft with an inspection plate on the top floor, which is fine but if your in a apartment complex, with a penthouse on the top, that means no access to the controller for breakdowns or maintenance which is a poor design and has a lack of forethought!!
