Q: What is elevator unintended car movement protection device? What technical and certification requirements apply for exports to different overseas markets? A: UCMP is a mandatory safety component emphasized by global elevator safety regulators in recent years, designed to prevent passenger clamping and falling risks caused by accidental car sliding while doors are open. Technical parameters and certification rules differ greatly across regional markets.

  1. Working principle of UCMP devices When the elevator stops at a floor and landing/car doors are open, once the control system detects unintended car movement, the UCMP device activates braking immediately to lock the car and avoid hazards. The complete system consists of signal sensors, logic control units and mechanical brake actuators.
  2. Mandatory requirements by regions European Union: In accordance with new EN 81-20/50 standards, all new and renovated elevators must be equipped with UCMP with independent braking capacity, covered by CE type certification for safety components. Southeast Asia: Indonesia, Malaysia and Singapore have updated building codes to enforce UCMP installation and accept test reports complying with EN standards. Central Asian Russian-speaking regions: The EAC certification system requires full UCMP functions, which must be verified during complete elevator type tests. Middle East: SASO audits refer to EN standards, focusing on brake response time and trigger reliability.
  3. Key production & supply tips for foreign trade exports UCMP can be exported independently as safety components or bundled with traction braking systems. Complete type test reports shall be provided with clear parameters including brake response time, applicable load and speed range. Products complying with the latest EN standards are recommended for EU shipments to avoid customs clearance obstacles.
