    6. TWO TYPES OF ELEVATORS 1. Hydraulic 2. Traction

    7. Hydraulic

    8. Hydraulic Elevator (holed) Guide Rails Door Operator Plunger & Cylinder Controller & Pumping Unit Hoistway Door To & From Oil Pipe

    9. Hydraulic Elevators - holed • Rise Limitations: ~ 60 feet • Cost: $35 - $85K • Speeds: 100/125/150 fpm • Advantages: • low cost • no penthouse • no structural load on building • Disadvantages • slow • energy inefficient

    10. Hydraulic Elevator (holeless) Door Operator Guide Rails Plungers & Cylinders Controller & Pumping Unit Hoistway Door To & From Oil Pipe

    11. Hydraulic Elevators - Holeless • Rise Limitations: 20 feet • Cost: $35 - $45K • Speeds: 100/125 fpm • Advantages: • no well hole • minimizes environmental contamination • Disadvantages: • limited travel

    12. Holeless: Roped Hydraulic

    13. Holeless: Roped Hydraulic Elevators • Rise Limitations: 60 feet • Cost: $45k - $75k • Speeds: 100 - 125 - 150 fpm • Advantages: • Eliminates well hole • Same 60’ travel range as “holed” hydro • Existing Building • Disadvantages • More costly than conventional holed hydraulic

    29. Bob Beyer Lecture Key Points • In the next 5 years 75% of all the elevators will be MRL ( Machine room less • MRLs will replace Hydraulic and Geared Traction type elevators • MRL have lower energy costs – up to 60% less than geared. (Only 2-3% of the total buildings electrical load is for the elevators) • Machine rooms must be air-conditioned • In office buildings above 5 floor you should have a dedicated service elevator (4500lbs. minimum size for service elevator) • 1 service elevator for every 2 passenger elevators in a hotel over 15 stories. • In the next 5 years al the signs saying “Do Not Use The Elevator In Case Of Fire” will be gone. Elevators are the safest way out of a building until the fire actually reaches the shafts ( which are two hour rated in high rise)
