The significant changes incorporated in this revision (Subsection 5A) include the following:
a) Definitions of various terms relating to energy dissipation and accumulation types, compensation means, hydraulic and electric systems, and safety mechanisms have been included to enhance clarity in performance measurement, seismic considerations, and maintenance aspects of lifts.
b) Introduction of double-deck lift systems, with two cabins arranged one above the other, optimizing shaft use and improving efficiency in high-traffic areas.
c) New provisions for two independent lift cabins in a single shaft solution address up-peak and inter-floor traffic demands.

d) Provisions of destination control systems (DCS) for call assignments, improving passenger flow and operational efficiency have been included.
e) Provisions for fireman’s lifts, including specific requirements for fire-rated doors [in 7.2.1.1(d)] and speed criteria (in 11.8) to ensure quick and safe evacuation.
f) Introduction of passenger evacuation strategies (in 11.8.1 and 11.8.2) for both independent and joined cabin systems, enhancing safety during emergencies.
g) Inclusion of hidden car operating panel for Fireman Control or special operations, improving safety and operational flexibility (in 11.7.1 and 11.7.2).
h) Updated guidelines for compensation rope systems, with specific measures for high-speed lifts to maintain required traction, in 11.7.2.
j) Expanded requirements for machine room levels based on lift speed and shaft dimensions.
