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 2021 edition of the Code of Practice on the Design and Construction of Lifts and Escalators serves as the primary regulatory benchmark for vertical transportation safety and engineering. This document provides the technical specifications required to ensure that all lifting equipment is designed, installed, and maintained to prevent accidents and ensure operational longevity.
The primary objective of the 2021 update was to harmonize local engineering standards with international safety protocols, specifically addressing advancements in digital monitoring and energy efficiency. For developers, architects, and engineers, adhering to this code is not merely a suggestion but a legal necessity to obtain building occupation permits and safety certificates. Key sections of the 2021 Code of Practice include:
General Design RequirementsThe code outlines the structural integrity required for lift wells and machine rooms. It specifies the load-bearing capacities for floors and the necessary clearances to prevent crushing hazards during maintenance. It also emphasizes the fire-rated integrity of landing doors to prevent the spread of smoke and flame between floors.
Safety Components and ProtectionA significant portion of the document focuses on safety gear and overspeed governors. The 2021 edition introduces stricter testing protocols for braking systems and buffers. It also details the requirements for Unintended Car Movement Protection (UCMP), which prevents the lift from moving away from the landing with the doors open.
Escalator and Passenger Conveyor StandardsFor escalators, the code specifies the exact angles of inclination, skirt deflector requirements to prevent limb entrapment, and the sensitivity of emergency stop buttons. It also mandates specific lighting levels at the comb plates to ensure passenger safety during entry and exit.
Electrical and Control SystemsModern lifts rely heavily on complex software and circuitry. The code sets standards for electromagnetic compatibility (EMC) to ensure that lift controls do not interfere with other building systems. It also covers emergency communication systems, requiring a dedicated power supply that remains functional during a building-wide blackout.
Maintenance and Inspection AccessTo protect lift technicians, the 2021 code mandates improved access to the car top and pit. It requires permanent lighting in the shaft and specific dimensions for "refuge spaces"—areas where a technician can safely stand if the car moves unexpectedly.
For professionals looking to download the "Code of Practice on the Design and Construction of Lifts and Escalators - 2021 Edition - PDF," it is typically hosted on the official portals of national building authorities or electrical and mechanical services departments. Accessing the official PDF ensures you are working with the most accurate diagrams, torque specifications, and legal definitions currently in force.

Code of Practice on the Design and Construction of Lifts and Escalators (2021 Edition) , commonly referred to as the Design Code , is a critical regulatory document published by the Electrical and Mechanical Services Department (EMSD) of the Hong Kong Government. Effective from October 1, 2022
, this edition succeeds the 2019 version to incorporate the latest international safety standards and technological advancements in vertical transportation. 機電工程署 Purpose and Legal Framework The Design Code is issued under the authority of the Lifts and Escalators Ordinance (Cap. 618)
. Its primary objective is to define the technical details, methods, and safety rules required to protect persons and objects from accidents associated with the installation and operation of these systems. While it serves as a technical manual for manufacturers and contractors, compliance is also a statutory duty for "Responsible Persons" (RPs), such as building owners and property management companies. CIBSE Hong Kong Region Key Enhancements in the 2021 Edition
The 2021 edition focuses on harmonizing local requirements with EN standards
(European Standards), which are globally recognized benchmarks for engineering excellence. Notable advancements include: CIBSE Hong Kong Region Improved Accessibility:
Enhanced "barrier-free" design requirements ensure that new installations are more usable for persons with disabilities, the elderly, and people with physical limitations like pregnant women. Operational Safety:
The code mandates stricter safeguards for both passengers and maintenance workers. For instance, it specifies precise horizontal distances between lift cage thresholds and landing thresholds (not more than 50mm) to prevent tripping during loading. Escalator Safety:
Following significant public incidents, the 2021 framework further tightens requirements for drive chains and braking systems. All drive chains in escalators with a vertical rise greater than 15 meters must now be replaced at intervals not exceeding six years. Emergency Devices: Updated acceptance criteria for the factor of safety
Failure of emergency devices—including alarms, lighting, and ventilation—must be attended to by contractors within 4 hours, reflecting the code’s emphasis on rapid response and passenger comfort. Buildings Department Design and Construction Standards
The Code outlines rigorous physical specifications for equipment to ensure structural integrity: Lift Cages:
Walls must extend from floor to roof and be capable of withstanding specific thrusts (e.g., 30kg distributed over 500mm²) without permanent deformation. Vision Panels:
For safety and transparency, solid lift cage gates must include eye-level vision panels made of shatter-resistant material. Security Mechanisms:
It is impossible to start or run a lift cage unless all gates are both closed and mechanically/electrically locked. Impact on the Industry
By aligning with the latest international standards, the 2021 Design Code facilitates the supply of compatible components from global manufacturers, fostering competition and efficiency in the Hong Kong market. It works alongside the Code of Practice for Lift Works and Escalator Works Works Code
