Conveyor rollers that get past the customer

[Earl Weiss]

In the cases I am talking about I have customers with two rollers between their front and back tire so when the roller behind the front tried to push them over the exit trap door and return the roller it cant because the second roller IN FRONT of the rear wheel does not give it enough play. The car is reasting on the trap door with the front roller unable to dissappear and the rear wheel preventing the car from moving forward.

I think it is inexperienced customers and not consciensciojus enougfh attendants to stop the problem at the front of the tunnel/

It may be partly that, but to an extent it is unavoidable.

If you have a roller behind the front whell pulling and one or more safety rollers behind the rear tire, some cars will lose th roller under the front wheel due to underinflated tires, misalignment, driver error, dragging brakes etc.

The issue is that the car should roll past the door by momentum / gravity. All of the above can inhibit this as well as floor (if you have an older wash ww\it a worn floor on the passenger side stell plating there will reduce the rolling resistance.) and conveyor pitch . The simplest assist to keep the whel rolling past the front trap door is the roll off plate. The above conditions would have to be severe, plus if there is no rail at this point (does there need to be? ) rail friction will not be an issue. You always can have some numb nuts who hits the brakes at this point, but otherwise it will tend to keep the vehicle rolling past the door.
