All lessons, in order (the list loops back to the start after the last one)

Videos play muted at first, because browsers only start playback on their own without sound. Press Sound on to hear them. Keys: N next, P previous, F full screen, M mute.

Crane safety: some lessons, such as 26 and 27, show crane stations and pick plans. They are planning aids, not lift plans. A crane must never stand across the slab edge: its tracks or outriggers go wholly on the poured slab or wholly off it, never part on each. Every lift on a real job is planned and reviewed by a qualified lift engineer.
