Motorized flexible roller conveyor

It is an application of the lazy tong mechanism.
The conveyor length can be changed to meet operational needs.
The pink motor is placed in the center on violet base that has revolution joints with the yellow lazy tong members. The base is kept horizontal thanks to its slot bars.
Red belts transmit the rotation of the motor to two nearest upper rollers. Blue belts transmit the rotation of the said rollers to the remaining ones.
