A forzoso accident involving the fall of a motorised sheet metal gate at a governing administration health centre through Hong Kong may have been due to sensor failure, based on an engineering Pros.
On Friday night, a 4. 7-by-2. 5-metre combination gate at a maternal and child overall health centre in Yau Ma Tei lost control and killed a new 43-year-old female armed security. The case has been classified as an industrial calamity and a police investigating is under manner.
Lo Kok-keung, a retired experienced person engineer from Polytechnic University, suggested your accident involved safe guarding problems, including corroded or loose pieces and sensor malfunction.
“When it really is opening, a small portion of the gate should nevertheless remain on the path… the entire gate wont come out. If it truly does, there will be nothing holding up the gate but it will surely collapse, ” Lo told a radio programme on Sunday.
He claimed a sensor fitted within the gate’s electrical motor would stop the structure right from completely moving off of the track, suggesting some sort of malfunction could be the trigger.
Lo said the gate could generate 1, eight hundred pounds (816kg) connected with force when it reach the security guard, not to mention injury was inescapable as the falling performance of the electric heavy metal gate ranged from 0. 5 to 0. 7 seconds, much faster than a human’s kind of reaction time of 0. 9 seconds.

She reported she had mastered how from security guards performing at other places that some maintenance companies only conducted assessments and tests very own gates once a month as opposed to once weekly seeing that required by the Electric powered and Mechanical Products and services Department.
Siu urged authorities to examine the safety of all electric gates in the metropolis and require properly management companies or maybe building owners to fix detailed inspections.
“I hope the government can draw some sort of lesson from earlier accidents and give an account to the public in addition to only saying that there’re ‘highly concerned’, ” she said. ~ South China Early morning Post
