Step 1: Go to the third level (the junkyard area)

Step 2: The moment you start turn left, lift up the plaform and jump across to the main area.(Where one of the 3 engines is located)

Step 3: Stand at the edge of the island facing where you have to go to progress in the level, you should see a ray of light into the sky.

Step 4: You should be able to target this ray of light and lift it using your force grab.
