2. FCC vs. LHC lifts
As for the LHC it is proposed to have two lifts per access point. But contrary to the LHC the two lifts shall operate next to each other in the same shaft and not in separate shafts as in the LHC. This has several advantages:
Less shafts required
Only one emergency staircase over the entire shaft length between the two lifts needed that are required to evacuate people from the lift cabin in case of a lift breakdown
Redundancy during the compulsory monthly maintenance interventions and annual safety inspections
Redundancy during corrective maintenance interventions and repair works

3. FCC layout vs. Lift layout
The FCC layout foresees 12 access points with 12 access shafts and 4 shafts for the Experiments. Only the 12 access shafts will be equipped with two lifts each.
The main lift parameters are:
Lift capacity: 3 t
Max. n° of people: 38
Lift speed: 4 m/s
Cabin dimension: 2.7*1.9 m

4. Baseline for studies - lifts
2 lifts of 3 t per shaft
A staircase between the lifts
Lift shaft dimensions :
W x L = 2.75 m x 3.75 m
Pit depth (HSG) = 3.55 m
Headroom (HSK) = 6.15 m
Need door in pit with external stairs (EN81-20)
Quotation update in progress

5. FCC lift vs. Shaft layout
The installation of two lifts in one shaft requires a shaft diameter of 12m. There should be still sufficient space (8*4m) for the ‘trémie’ in which the EOT crane can lift material via the shaft from and to the underground areas. On the opposite site of the lifts will be space left in the shaft to install services such as piping, ventilation ducts and cables (similar to how it was done for the LHC).

8. FCC lifts vs. CE
The lifts can be installed as soon as the lift shaft modules and the ventilation system are installed and operational. The shaft tolerances must be +/- 35mm!
The piston effect has also to be taken in consideration:
Single shaft: Shaft Area > 2 x Car Area
Multi shaft: Shaft Area > 1.5 x Car Area

9. Lift cycle vs. People underground
The lift capacity and speed will determine how many people are allowed to work in the underground areas simultaneously. For example:
1 lift cycle for evacuation purposes is about 4 minutes for a ~300m shaft depth
1 minute for entering the lift at the bottom of the shaft
1.25 minutes for lift travel from bottom to top
0.5 minute for exiting the lift on the top
1.25 minutes for lift travel from top to bottom

(2*35 people)
Max. number of evacuated people 1 4 70 2 8
140 3 12
210 16
280 5 20
350
Since both lifts can operate simultaneously it can be assumed that
up to 350 people can be evacuated within 20 minutes from the
underground areas via one access shaft.
Numbers to be validated by HSE!

11. FCC Lift costs
The costs for the lifts depends mainly on the travel height and the speed:
Height
Speed
Capacity
Price (CHF)
150 m
4 m/s
650 kg
400 m
8 m/s
630 kg
 900’000
3000 kg
250 m
1'000'000
Please note that the lift capacity is not such an important factor since this weight is only marginal compared to the total weight of steel wire ropes considering the important travel length.

12. FCC lifts vs. Applicable standards
The lifts will be manufactured according to the following norms:
Elevator Codes EN81-20/50, EN , EN81-73
EMC EN12015 / EN12016
Ride Quality ISO18738
I. Rühl / EN-HE

13. All numbers still need to be confirmed and / or cross checked namely with HSE, CE and lift suppliers.
