ISO 4190-1:2010 pdf free download – Lift (Elevator) installation一 Part 1: Class I, II, III and VI lifts.
Minimum depth: 2d2 + distance between the wells.
In the case of an odd number of lifts, i is rounded up to the next even number.
4.4.2.2.4 Height
The minimum height of the common machine room shall be equal to the height of the machine room having the greatest height.
Machine room heights are subject to existing national regulations.
4.5 Dimensions of machine room for hydraulic lifts
4.5.1 Individual lifts
The dimensions of the machine room shall be as indicated in Tables 3 and 4. Machine room heights are
subject to existing national regulations.
4.5.2 Duplex group lifts
For both lifts, a common machine room is recommended.
The floor area shall be as follows.
a) Duplex group lifts having the same rated load: the minimum floor area of the common machine room shall be equal to the sum of the minimum area required for machine rooms placed behind the well of individual lifts.
b) Duplex group lifts having different rated loads: the minimum floor area of the common machine room shall be equal to the sum of the minimum areas required for machine rooms placed behind the well of individual lifts plus the difference between the well area of the two lifts.
4.6 Arrangement of machine room
4.6.1 Individual or common arrangement
4.6.1.1 This part of ISO 4190 is based on a configuration of a machine room above the well. For electric lifts, the lateral extension of the machine room with respect to the well (or common well) can be taken on either the right or the left of the well (see Figure 3).
4.6.1.3 The machine room should have adequate ventilation.
4.6.2 Arrangement for individual lifts and multiple lifts side by side with common machine room
4.6.2.1 For electric lifts, the rear wall of the machine room shall be in line with the corresponding well wall (or of the deepest well) and one of the lateral walls shall be in line with the corresponding well wall (or of the common well).
The depth extension of the machine room, with respect to the well, shall be taken on the landing side.
4.6.2.2 For duplex group hydraulic lifts, the common machine room is preferably placed behind the well in the lower part of the building.
4.6.3 Arrangement for lifts face to face with a common machine room (for electric lifts only)
It is recommended that any depth extension not be greater than 0,5 m from the rear walls of the wells and be at the same level as the slab supporting the machinery.
