    Leaf Spring Design

    @desertfox 1. These comes with feed back unit to track from Station 1 to Station 2. Condition the unit has to be in contact with pallet below 2. The unit is lifted on to module using CAM mechanism. 4 wheels will not be in contact with ground when this happens (for brief amount of time)...
