Chain hoists
Pull the hand chain on a 1 ton hoist and watch the hook rise. See how the pull follows the load, why lever hoists don't get cheater bars, and what to check before every lift.
Open full screen · 5 pages · 7 practice questions · narrated (AI voice) · exam preparation only: always check the tag, the manufacturer's data and your lift plan.
What's in the lesson
- Pull the hand chain. A 1 ton hand chain hoist hangs from a beam clamp on the bottom flange of a shop beam.
- Pull follows the load. The same 1 ton hand chain hoist (rated 2,000 lb, 58 lb of pull at rated).
- Lever hoists and cheater bars. A 1 ton lever hoist (come-along) on the same beam clamp.
- Check it before you lift. Before each lift: the hook (throat, twist, latch), the load chain (wear, twists), and the brake (does it hold a trial lift?).
- Putting it together. A 2,400 lb motor (weight from the nameplate) has to come up 2 ft.
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.
Exam preparation, not a procedure. On the job, check the tag, the manufacturer's data and your lift or work plan.
