Safety rules for the construction and installation of lifts. Special lifts for the transport of persons and goods. Vertical lifting platforms intended for use by persons with impaired mobility | Status: Current

1 Scope 1.1 This document deals with safety requirements for construction, installation, maintenance and dismantling of electrically powered vertical lifting platforms affixed to a building structure intended for use by persons with impaired mobility:

• — travelling vertically between predefined levels along a guided path whose inclination to the vertical does not exceed 15°;
• — intended for use by persons with or without a wheelchair;
• — supported or sustained by rack and pinion, rope traction drive, traction drive, rope positive drive, chains, toothed belts, screw and nut, guided chain, scissors mechanism or hydraulic jack (direct or indirect);
• — with enclosed liftways;
• — with a rated speed not greater than 0,15 m/s;
• — with carrier not completely enclosed.

1. 1.2 This document deals with all significant hazards relevant to lifting platforms, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4).

Those hazards have been considered for each component that may be incorporated in a complete lift installation and rules have been drawn up accordingly. Components are:

1. a) designed in accordance with the usual engineering practice and calculation codes, including all failure modes;
2. b) of sound mechanical and electric construction.
