A Critical Review of the Code of Practice on the Design and Construction of Lifts and Escalators (2021 Edition): Enhancing Safety and Technological Adaptation
The inclusion of software-based safety systems challenges traditional inspection methods. Authorities must now assess code compliance not just through physical inspection, but through verification of software validation documents.
Complying with the Code of Practice (2021 edition) requires integrating statutory clauses into every design stage, coordinating multidisciplinary inputs, performing rigorous testing and maintaining complete documentation. Following the structured workflow, checklists and mitigation strategies above reduces risk, streamlines approvals and improves safety and reliability for lifts and escalators.
The revision provides more detailed requirements for safety components, including braking systems, skirt deflectors, and emergency stop systems, significantly reducing entrapment and injury risks.
The code requires that lifts and escalators be equipped with various safety features, including: A Critical Review of the Code of Practice
It is highly recommended that all stakeholders in the lift and escalator industry download the relevant circulars, review the amendments, and ensure full compliance with the 2021 Edition for all new projects.

Prior to public handover, a certified independent inspector must conduct full-load drop tests and structural verifications.
The code covers two primary system categories: traction/hydraulic lifts and passenger escalators/moving walks. Code of Practice (805) or TK Elevator
When tendering for Otis, Schindler, Mitsubishi, or TK Elevator, attach the as a contractual requirement. Many standard products are built to EN 81-20 or -50; the Hong Kong code adds local demands (e.g., higher emergency battery capacity due to unstable mains).

The code sets out rigorous physical and mechanical requirements for all new installations: Standard Requirement Lift Passenger Weight Each passenger is calculated at a standard weight of Lift Interior Height Clear height inside the lift cage must be at least Escalator Speed 0.5 to 0.65 m/s (up to 1.0 m/s for deep systems like subways). Escalator Inclination Standard angle of (35° allowed for rises

In regions prone to earth movements, lifts must feature seismic triggers that safely park the car at the nearest available floor to prevent derailment within the shaft. Inspection, Testing, and Compliance Lifecycle
The 2021 Edition marks a major step forward from the older 2012 and 2019 editions. While past updates focused on minor part revisions, the current version harmonizes local engineering practices with the international standard framework. Key Milestones and Timelines
