Title: A Critical Review of the Code of Practice on the Design and Construction of Lifts and Escalators (2021 Edition): Enhancing Safety and Technological Adaptation

Abstract

The vertical transportation industry serves as the circulatory system of modern urban infrastructure. As buildings grow taller and public reliance on mechanized transport increases, the regulatory frameworks governing safety must evolve. This paper provides a comprehensive analysis of the Code of Practice on the Design and Construction of Lifts and Escalators – 2021 Edition. It examines the key revisions introduced in this edition, specifically focusing on the integration of modern safety standards, the accommodation of new technologies, and the alignment with international best practices (such as EN 81 and EN 115). The analysis reveals that the 2021 Code represents a significant paradigm shift from prescriptive requirements to performance-based safety outcomes, aiming to reduce risk while facilitating innovation in smart building environments. The Code of Practice on the Design and

3. Key Revisions and Innovations in the 2021 Code

The 2021 Edition introduces several critical changes designed to align the industry with current technological realities.

2. Introduction and Objectives

Step 1: Cross-Reference with Building (Planning) Regulations

The Code of Practice on lifts interacts with other building codes. For example, the number of lifts required depends on building occupancy (from the Buildings Department), but the design and construction details—car speed, door dwell time, emergency power—come from the 2021 code of practice.

What is the Scope of the 2021 Code?

Unlike general building codes that focus on structural integrity, this specific code of practice dives deep into the electromechanical heart of buildings. It covers:

• Passenger and goods lifts (traction and hydraulic)
• Escalators and moving walks
• Safety components (governors, safety gears, buffers)
• Machine-room-less (MRL) lift designs
• Electrical installations and control systems
• Firefighting lifts (a key section updated for high-rise safety)

The 2021 edition explicitly aligns with the latest BS EN 81 series standards but adds local amendments for Hong Kong’s dense urban environment, typhoon conditions, and power supply reliability.
