This standard specifies the safety rules for the construction and installation of permanently installed new electric service lifts with traction or positive drive, or hydraulic service lifts defined as lifting equipment serving defined landig levels, having a car, the interior of which is regarded as inaccessible to persons on accunt of its dimensions and means of construcation, suspended by ropes or chains or supported by a ram and movvind and between rigid vertical guide rails or guide rails whose invlination to the vertical does not exceed 150 and driven electrically or hydraulically . this standars covers service lifts with rated load not exceeding 300 kgs and nt intended to move persons. In addition to the requirements of this standard, supplementary requirements shall be considered in special case (potentially explosive atmosphere, extreme climate condition, seismic conditions, transporting dangerous, goods, etc). This standard does nt cover: a-service lifts with drives other than stated in section1.1; b-important modification ( see annex E ) to a service lift installed before this standard is brought into application; c- lifting appliances, such as paternosters, mine lifts, theatrical lifts, appliances with automatic caging, skips and hoists for building and public works sites, ship hoists, platforms for exploration or drilling at sea, construction and maintenance apppliances ; d-installations where the inclinaton the guide rails to the vertical exceed 15 0; e-safety during transport, installation, repairs and disamantling of service lifts; f-the use of glass for the walls of the well, for the car and for the landing doors including the vision panels. However, this standard may usefully be taken as a basis Noise and vibration are not dealt with in this standard because these are not relevant to the safe use of the service lift fire propagation is not dealt with in this standard. To satisfy the condition of inaccessibility to the car, the car dimension shall not exceed: a-for floor area 1.0m2 b-for depth 1.0; c-for height 1.20m the height of 1.20 m shall not be limited if the car comprises several permanent compartments , each of wich satisfies the above requirements. In particular, lifting equipement intended exclusively for the transportation of goods , but having a car with dimensions exceeding any one of the figures above shall not be entered in the category service lifts. This standard covers the safety requirements for service lifts with rated speed up to 1 m/s. NOTE: for service lifts with higher rated speeds additional requirements shall be applied as appropriate in order to maintain the same level of safety
