Posted on 25 Aug 2011Wheel comes off bus in freak accident
The rear wheel appears to have come detached from this bus that STOMPer Nicholas was on. The STOMPer felt that there was something wrong duringthe ride on SMRT service 854 and when the bus stopped, the wheel was found to be inthis state.
The STOMPer said:
"I was travelling from Yishun when I felt there was something wrong with the rear tyre.
"True enough we stopped off at a bus stop and the tyre was in this position.
"There seems to be no bolts holding it to the bus. The small piece on the ground is one of the bolts.
"If you looked closer, the bolts seem to have popped out."
*Bus is reported to be TIB578H.

sheared hub bolts

Maybe SMRT Buses could consider installing similar coil wires that SBS Transit is using on their fleet on the nuts of the wheel to minimise such incidents.

lucky wheel never come off when bus turning or something jialat....otherwise might be worse case.

The centre line is very very serious case. Involves safety issues.
Like who ok the bus to leave the depot?
BC conducted pre-start inspection before moving out?
How far did the bus travel before enough nuts and bolts came off?
How? Were safety checks compromised?

pls define the center line
BC should hav heard the knockin noise before it came off
seems the travelin speed is slow before it happened.from picture - some bolt holes r bigger than normal so seems its not a 1 day proceeding or some of the nuts were not even there from day 1
i dun work for sbs or smrt so no idea on their daily pre-operation checks

"just someone forgot to torque up the nuts"
There is a whole lot of issues in this "just someone forgot...."
Investigations will always reveal serious lapse in following the SOP.

ok, if the rim bolt holes are bigger than normal . tat is usual case of not torque up
if tat stud on the ground belongs to this bus. it wld be a more serious case than not torque up only -
Yah, from the technical point of view, the damage would not be severe. That is fortunate.
I was viewing from the safety aspect of the incident. How was the vehicle passed after maintenance/repair works?
The famous question, What If ? The bus was travelling full speed on the expressway, with pasengers? The maintenance crew are taking short cuts?
The consequences could be very unfortunate.

even there are mixed bags of equipment for the mechaincs to repair, I suppose this is more to human error than engineering
but gud operators are just as important as gud mechainics
