Hi. Our DR4B’s chain bar is not functioning correctly. The goliath intake does not go aligned with the floor and the chain bar won’t lift backwards. I don’t think it is a programming problem and is probably due to the motor’s torque insufficiency or some other engineering problem. Can you suggest what the problem is? Or how to fix it?
After a closer look, it’s simply your overall construction that’s causing the issue. I recommend moving the lift motors to the towers, then making sure the system is as frictionless as possible and that nothing sticks out too far, etc.
