Linear Door Operator Recommendations

Looking for recommendations for a linear door operator to replace an Otis 7300. We will be modding these Otis hydro cars with EC controllers. Thank you

We always go with GAL. Have not let us down yet.

We used the Otis Glide door op with MCE controls and are currently installing 3 more with smartrise controllers. Kept the skate and didn’t have to replace door locks, works great.

I would also use GAL. It works great.
I wonder why people still buy smartrise controllers.

I would recommend either the GAL MONXT or the Wittur SGV (AMD and LD-16 similar).

Both of these door operators are European style, which typically have more safety features, such as cabin door interlock (no gate switch, which could get purposefully or inadvertently activated at the wrong time, and no "less reliable" door restrictor, which could become a snag hazard, in the case of the angle-iron variety, or purposefully jammed in the unlocked position by a tech, in the case of the GAL/MAC?Miami Elevator variety, or even worse jam in the locked position, in the case of Adams HatchLatch). With interlock, door cannot be moved ajar. The clutch engages independently from the door movement, reducing a snag hazard due to misaligned doors. The doors can't be split apart at floor level causing door lock faults due to the clutch design.

In your case, I would recommend the Wittur product because it comes with a kit allowing you to retain your existing 6940 hall locks (adapter bracket req. for snubber roller); however you will have to replace the tracks on the cabin side and also the skate. Also, parts are available from multiple sources (KONE, TKE/Vertical Express, and Wittur) Link: https://verticalxpress.com/media/download_files/component_manuals/ld_16_udo_mod.pdf

The second choice would be the GAL MONXT. Unlike the Wittur product, you will need to rehang the doors with GAL hardware and also replace the door skate and the hall locks. This might be acceptable for just a few stops.

Whatever you do, I wouldn't recommend harmonic op. They are just too outdated and don't offer all the safety features of Euro style operators. GAL is the only company that still makes em. They need to stop, lol.
