ČSN EN 81-22 ed. 2 1.1 This document specifies the safety rules for the construction and installation of permanently installed new electric lifts, with traction or positive drive, serving defined landings levels, having a vehicle designed to convey passengers or passengers and loads, suspended by ropes or chains and travelling in a vertical plan along guide rails that are inclined at an angle of between 15° and 75° in relation to the horizontal. 1.2 In addition to the requirements of this document, supplementary requirements should be considered in special cases (potentially explosive atmosphere, extreme climate conditions, seismic conditions, transporting dangerous goods, etc.). 1.3 This document does not cover: a) lifts with drives other than those stated in 1.1; b) installation of electric lifts in existing buildings to the extent that space does not permit; c) important modifications (see Annex E) to a lift installed before this document is brought into application; d) lifting appliances, such as paternosters, mine lifts, theatrical lifts, appliances with automatic caging, skips, lifts and hoists for building and public works sites, ships' hoists, platforms for exploration or drilling at sea, construction and maintenance appliances; e) safety during transport, installation, repairs, and dismantling of lifts; f) lifts with rated speed <= 0,15 m/s. However, this document can usefully be taken as a basis. Noise is not dealt with in this document because it is not relevant to the safe use of the lift. Vibrations are dealt with for electric parts only. Direct effects on human bodies are not considered as harmful. 1.4 This document does not specify the additional requirements necessary for the use of lifts in case of fire. 1.5 Taking into account the state of the art, the scope of the present standard is limited as follows: - inclination: a variation in inclination is permitted for the travel path; - travel path: confined within the vertical plane; - maximum capacity of the car: 7 500 kg (100 passengers); - maximum rated speed (v): 4 m/s. Both characteristics (capacity and speed) are linked by the relation given in the following Figure 1. |
