intended for the transport of persons or persons and goods. It applies to traction lifts, positive drive lifts and
hydraulic lifts that:
— serve specific levels; and
— have a rated speed exceeding 0,15 m/s; and
— have an enclosed car; and
— move along guide rails inclined not more than 15° to the vertical; and
— are indoor or weather-protected.
This document also applies to the electrical equipment of these lifts including the lighting and socket outlets
in the well.
This document specifies safety rules related to:
— persons to be safeguarded:
— users, including passengers, maintenance and inspection personnel;
— persons at the landings and outside of the well, or any machinery space and pulley room, who can be
affected by the lift.
— property to be safeguarded:
— loads in the car;
— components of the lift installation;
— building in which the lift is installed
This document does not specify additional requirements for:
— lifts serving buildings with requirements for seismic conditions;
— lifts serving buildings with requirements for accessibility;
— lifts exposed to vandalism;
— lifts which can be used for firefighting and evacuation purposes under firefighters control;
— lifts which can be used to support faster evacuation of persons with disabilities;
— the behaviour of the lift when the control system of the lift receives a recall signal(s) in the event of fire
in a building.

— on the car roof, where it is not possible to alert via inside the car as per 4.2.6.4.3.1 c); and
— in the pit or underneath the car, where an access door to the pit is not provided.
The alert initiation device(s) shall:
a) be connected to a two-way communication system in accordance with EN 81-28:2025; or
b) activate an acoustic device with a sound level of 80 dB(A) at 1,00 m distance, located on the car roof or at
a landing. The acoustic device shall be powered by the emergency supply as per 4.10.11.
NOTE National or local regulation can require a).
4.2.1.5 Forces
4.2.1.5.1 The vertical force beneath each guide rail shall be calculated considering the relevant forces
amoungamong the following ones: the force due to the mass of the guide rails, loads due to components fixed
or linked to the guide(s) and/or any additional reaction, occurring during emergency stopping (e.g. load on
traction sheave due to rebound when machine on rails), the reaction at the moment of operation of the safety
gear and any push through force exerted by the guide rails clips (see 4.7.2.3.5).
NOTE freelyFreely hanging rails do not contact the pit floor during normal operation, but there are spot cases where
forces can be transmitted to the pit floor (i.e. during guide rail installation and during a safety device actuation on the
guide rails).
4.2.1.5.2 The vertical force beneath the car buffer supports shall be calculated as four times the static load
imposed by the mass of the fully loaded car, evenly distributed between the total number of car buffers [see
Formula (1)0]:
𝐹=4⋅𝑔 ⋅(𝑃+𝑄) (1)
n
where
F is the total vertical force in newtons;
gn is the standard acceleration of free fall, [9,81 (m/s )];
P is the mass of the empty car and components supported by the car, i.e. part of the travelling cable, compensation
means (if any), etc. in kilograms;
Q is the rated load, in kilograms.
4.2.1.5.3 The vertical force beneath the counterweight buffer supports shall be calculated as four times the
static load imposed by the mass of the counterweight, evenly distributed between the total number of
counterweight buffers [see 0]:
𝐹=4⋅𝑔 ⋅(𝑃+𝑞⋅𝑄) (2)
n
where
F is the total vertical force in newtons;

P is the mass of the empty car and components supported by the car, i.e. part of the travelling cable, compensation
means (if any), etc. in kilograms;
Q is the rated load, in kilograms;
q is the balance factor indicating the amount of counterbalance of the rated load by the counterweight.
4.2.1.5.4 For hydraulic lifts, the vertical force beneath each jack shall be calculated as the loads and forces
(in newtons) imposed to it.
4.2.1.5.5 For lifts equipped with a device as per 4.6.50 or 4.4.2.2.10 d) 1), the fixed stops shall be able to
withstand the vertical force imposed on the stops by the device as calculated by:
a) Formula (3)0 for devices provided with energy accumulation type buffers;
3⋅𝑔 ⋅(𝑃+𝑄)
