Corner post elevators - any comments?greenspun.com : LUSENET : Elevator Problem Discussion : One Thread
I am an architect in NYC working on a building design in which a new hydraulic elevator will be installed in an addition to an existing building. The shaft will abut the existing exterior building wall, meaning that one of the four shaft walls will be the brick exterior wall. A corner post elevator has been selected for functional reasons, but I got an estimate from a Dover rep of more than $100,000 (furnished and installed) for a 4-stop, 3-front and 2-side openings, 9'-6"x7'-6" shaft size. This seems high to me, but I haven't been able to get competitive pricing yet. A few questions: Does $100,000 seem like a reasonable estimate? What problems might I encounter trying to attach the rails to both the existing building wall and the new shaft walls? The structural engineer does not expect lateral movement. What, exactly, is the rail attachment detail for corner post elevators? Are there any other concerns I should be aware of in spec'ing the corner post? Thanks -- I appreciate the help.

Have you looked at the possibility of using a roped hydraulic cantalevered car. These units are much less expensive than a cornerpost and you can even save more by not having to drill a hole in an existing building. There are at least 4 or 5 manufacturers and dozens of installers that can handle that project. The last one we did that was 4 front 1 side was in the $ 60,000 range in PA.

Can you give me the names of manufacturers of this type of car? I'd like to get some more information to see if it would work for my project. Thanks for the response.

Shindler came out with a cantilevered car about a year ago it is called a 321A. Need to know what kind of Project!

Im courious,does these hydro roped cars have safties and a govner?
i guess my question is you got more moving parts and got to have safties plus a overhead, ropes ect and its cheaper?how fast does it travel in f.p.m. and its max wieght.

100K seems a reasonable price to me in NYC. Corner post construction is very costly as everything is special and "one off". If you could configure the hoistway to be front and rear instead, it would help greatly.
A roped cantilevered hydraulic is more of a part of the problem than a part of the solution. The very name gives you a clue.
