holeless hydraulic vs. cylinder

greenspun.com : LUSENET : Elevator Problem Discussion : One Thread

In a new 60 bed nursing home application , 2 elevators serving 3 floors of 17,500 sf each, 13' floor to floor - is there a reason NOT to use the cheaper holeless elevator rather than a cylinder model? - Schlindler is the brand we are considering

-- William Ware (bware@msconst.com), November 12, 2002


Assuming that hydraulic elevators are suitable for the application and that the other specifications (as to size, speed, etc.) are suitable and that the holeless design does not involve telescoping sections, the answer is "NO".

Holeless hydraulic elevator

William, I agree with Mr. Brannon's comments. I would like to add that you may want to ask Schindler if their equipment is non-proprietary?

Proprietary equipment may be less money to install, but how much will it cost you when only one or maybe two companies can work on it?

Timesaving installation. Energy efficiency. Environmental protection. Design flexibility. Enhanced safety systems.

Space Saving, Energy-Efficient, Clean The Gen2 system requires no machine room - the mechanism is at the top of the shaft. Lightweight, flexible, polyurethane steel belts permit the use of an energy-efficient machine.

Better for Architects, Builders and Owners The Gen2 system liberates architects to design buildings without the need for a machine room. Builders benefit from a rapid, controlled installation process that minimizes external trade interference. And owners enjoy an economical transportation system with more rentable space.

Clean, Efficient, Better for the Environment The Gen2 hoist stays clean as the belts and the gearless machine (which has permanently sealed bearings) require no oil.
