scope:
This standard 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 strait path along guide rails that are inclined at an angle of between 15° and 75° in relation to the horizontal. In addition to the requirements of this standard, supplementary requirements shall be considered in special cases (potentially explosive atmosphere, extreme climate conditions, seismic conditions, transporting dangerous goods, etc.). The scope of this standard has been deliberately limited in view of the current state of the art to such moving devices as the following: inclination : a variation in inclination is allowed for the guideway; travel path : confined within the vertical plane; maximum capacity of the car : 7 500 Kg (100 passengers); maximum rated speed (v): 4 m/s. These both characteristics (capacity and speed) are linked by the relation given in the following Figure 1. For the applications requiring superior specifications or those do not fall within the fixed limits or for lifts with curved path, a risk analysis shall determine at least the measures needed to reach the safety level fixed by the lift Directive. The standard applies to all the constituent components of the including: running tracks, guides, safety gear operating device, counter-rails, but excludes the supporting structures, civil engineering structures and anchorages that are dealt with by other regulations.
