Escalators & moving walks EN115-1
EN115-1 2008 philosophy:
 The purpose of this standard is to define safety requirements for
escalators and moving walks in order to safeguard people and
objects against risks of accidents during installation, operation,
maintenance and inspection work.
 Escalator acc. EN 115 definition: continuously moving stairway
used for raising and lowering passengers.
It is not recommended to use escalators as regular staircases or
emergency exits.
 The same safety requirements for all types of escalators
(commercial and public use).

Escalators & moving walks EN115-1
EN115-1 2008 clause 3, terms and definitions:
Nominal speed: Speed in direction of the moving step, pallets or belt
under no load conditions
Rated speed: Speed to move the escalator / moving walk under
rated load conditions
Rated load:
Load at which the equipment is designed to move
passengers (capacity)
Structural load: Load at which the escalator / moving walk supporting
structure is designed
Brake load:
Load at which the brake system is designed to stop
the escalator / moving walk
Clear definition of electrical safety systems / devices; safety circuits
/fail safe circuits
