We are looking to modernize several elevators - all 11 stops. Existing machines are geared, Hollister-Whitney, basement traction - most in machine rooms on the roof in sidemount configuration, two in a basement machine room.
Any recommendations on geared vs gearless for the mod? Are gearless even a viable option given the existing basement/sidemount machines?
Thanks for any thoughts.

Thanks for the input. In this thread it appears everyone is recommending gearless: http://www.vatortrader.com/forums/ubbthreads.php?ubb=showflat&Number=23822Most consultants we've spoke with seem to suggest the trend is gearless. If that's the case, wondering if in 20-25 years we would wish we had gone gearless - if for example it becomes harder to find good support for geared, higher maintenance costs, etc. We've had issues with a machine not being maintained properly leading to very costly repair. Maybe that just means we need better quality service - but wondering if gearless is more foolproof and if that's a legitimate benefit.

Ya, we did a geared to gearless mod on 4 basement traction cars last year. They turned out really nice. They had old Dover geared machines and we put in SC400 German machines. Thyssen discontinued the GD series geared machines so we’re really pushing geared to gearless. Usually it’s a Torin machine but I’ve also seen Imperial on one job. From a service standpoint though, I sure prefer the gearless machine.
