    Hi Aleksandar,

    The best book to learn about elevators is Mechanical & Electrical Equipment for Buildings , which is one of the books that is listed by NCARB Handbook and in my opinion crucial to pass PPD. Also, I learned a lot from this link about elevators: https://www.archtoolbox.com/materials-systems/vertical-circulation/elevatortypes.html#:~:text=Machine%2DRoom%2DLess%20Elevators%20are,maintenance%20or%20repairs%20are%20required.

    The last advice I can give would be checking elevator companies’ websites and check their specs for different types of elevators. 

    Hope this helps.

    Hi Elif,

    Thanks for the advice. I haven't checked out the elevator related sections in the "MEEB" book.

    I have the 12th edition, and was unaware that elevators were covered by the book.

    Online, i found a website called "elevatorpedia" which had helpful information (although a bit cumbersome to navigate). Seems like almost all MRL elevators are "gearless traction" (even though both gearless traction and hydraulic MRL elevators exist)

    the archtoolbox.com website seems also like a great resource.

    Elevators are an up and down subject. ooooh!

    THE ONLY SECTION IN MEEB I read was ELEVATORS because I DID NOT UNDERSTAND which one when and why.

    some facts on elevators:

    Machine Room Less - are both geared and gearless traction options.  They are used often when the floor area is at a premium. 

    FYI - there is a type of elevator that I had never had any exposure to called a HOLELESS HYDRAULIC elevator.  It is a low rise elevator for situations where the soil can not support an elevator shaft OR the building site has a high water table (so drilling a hydraulic hole would be dangerous to the environment)

    Hydraulic are basic slow elevators for service and people elevators up to max 6 floors (or 60 feet).

    Gearless traction are faster.

    BANKS OF ELEVATORS do not require as much power as a single elevator  - i.e. there is a POWER REDUCTION FACTOR applied because NOT ALL ELEVATORS operate at once.  This is explained really well in MEEB page 1500. 

    Mark, Archizam
