The Code of Practice on the Design and Construction of Lifts and Escalators (2021 Edition) represents a significant revision of the regulatory standards governing vertical transportation systems. Published by the Electrical and Mechanical Services Department (EMSD) — [Assuming Hong Kong context as this is the standard title used there] — the Code came into effect to enhance public safety, align with international technological advancements, and incorporate lessons learned from incident data over the preceding years.
| Category | Equipment Covered | | :--- | :--- | | | Standard electric lifts, hydraulic lifts (with rated speed up to 1.0 m/s), service lifts, fireman's lifts, and stairlifts. | | Escalators | All standard escalators. | | Other Systems | Pallet-type and belt-type moving walks, as well as powered vertical lifting platforms for wheelchair users and people with ambulant disabilities. | | | Other Systems | Pallet-type and belt-type
– This is likely from the Buildings Department of Hong Kong (or a similar jurisdiction, such as Singapore or the UK). The 2021 edition is often a Hong Kong Code of Practice.
: Must be highly visible, easily accessible at both terminals, and protected against accidental activation. ⚡ Electrical, Fire, and Emergency Standards an MRL system
Escalators demand rigorous dynamic engineering due to continuous passenger loading and constant motion. The 2021 Code of Practice provides exhaustive clauses targeting high-traffic wear and public entrapment risks. Inclination and Geometry The angle of inclination for escalators cannot exceed 30∘30 raised to the composed with power for standard rises, though it may extend to 35∘35 raised to the composed with power
