Hitches

What's in the lesson

1. Vertical hitch. A 1/2 in wire rope sling, eye and eye, hangs from the crane hook to a shackle pinned through the motor's own lifting eye.
2. Choker hitch. A 2 in, 2-ply polyester web sling is choked round an 8 ft steel pipe that rests on cribbing.
3. Basket hitch. One purple polyester roundsling (tag: 2,600 lb vertical, 5,200 lb basket) cradles a pipe.
4. Sling angles. A two-leg 1/2 in wire rope bridle: both top eyes on one master link in the crane hook, each bottom eye on a shackle pinned through a lug on the beam.
5. Putting it together. A 2,400 lb gearbox (weight from the maker's manual) sits on a pallet.

How it works

• One idea per page, each built around a simulator you work yourself. The last page puts it all together on one job.
• A narrator reads each step aloud. Mute it or slow it down at the top right, or read it yourself.
• Each step tells you what to do and what to watch. Stuck? Hint, then Show me: the simulator does it, then hands back.
• Practice questions along the way. Pick a wrong answer and you see why it's wrong, then get a new, similar question.
• After the steps, free play: every control unlocked, Reset, and "Give me a challenge".
• Nothing locks. Back and Next always work, and your place is kept in this browser.
• Print the short summary sheet: the rules and key numbers, light on toner.
