door open ......bus ca n still move
-
About an hour ago i took 169('citaro'bendy) from sembawng rd to woodlands.
on the admiraty road the 2nd door open(do not noe y,maybe driver accidently press) . he notice it only after some time. But when the door was open the bus can still move normally.I thought there is a device that prevents the bus from moving more than 5or10km/h if the doors are open????? -
The acceleration lock may have been deactivated when the other doors are closed.Originally posted by bus911:About an hour ago i took 169('citaro'bendy) from sembawng rd to woodlands.

Care to elaborate more on the issue? For example, the door opened when the bus is moving, the service capt only opened one bus or?
If only one door is opened, the explanation could be that the locking device is only activated when all doors are opened. -

it is possible tat the acceleration lock may have been deactivated when the other doors are closed. however it would most likely be an one-off incident of conincidence assuming the locks are not "really" faulty. but given the length of service of the Citaros, the lock system may have started to wear out.
the locking device is activated when any of the doors are open and deactivated when all of the doors are closed. tis is noted by the clicks & gas-release produced by the bus. however there are noted 2 observed exceptions: 1) for Habit ZF series 1147-1176 it appears only the 2 rear doors are under lock. 2) for all Voith series it is possible tat the brake pedal-induced lock (as observed by a click near the driver's seat when the brake is depressed for 3 secs) could interfere with the door-induced lock since both use the same lock system. thus it is possible tat the driver about to leave a bus stop may have released his brake pedal before the door has fully closed and deactivated the lock (noted by gas-release). -
Hey there everyone!
Actually... Even some of the Scania L113s and ELBOs too can move even without closing both the doors. I've even seen one incident before... The service captain opened both doors while slowly down at a fast speed, which to me's really dangerous. Wont any passenger nearly got flown out of the bus? I do wonder...

I heard from one of the drivers I know, that the locking device can be turned off using a "switch" near the door controls. On most buses there are 2 of these switches covered by red caps, but I'm not sure which one turns off the locking device.
On certain Habits the locking device is modified to lock only the exit service doors. IMO it's probably because some of the entrance electronic doors have problems closing; only by accelerating the bus slightly, then the door will close properly.
