Beam clamps and anchors

What's in the lesson

1. Does the clamp fit?. The beam seen end-on: a 2 ton beam clamp grips the bottom flange; its jaws hook over both flange edges and the screw pulls them tight.
2. No side pull. The same clamp, but the load sits off to the side, so the hoist chain leans.
3. Trolleys and end stops. A 2 ton push trolley on a monorail beam: four wheels ride on the bottom flange, a chain hoist hangs under it and you move it by pushing the load.
4. Snatch block anchors. A snatch block hangs from a 3/4 in shoulder eye bolt (WLL 7,200 lb in line) in a column bracket.
5. Putting it together. A 3/4 in shoulder eye bolt (WLL 7,200 lb in line; Crosby: 65 % at 30°) holds a snatch block.

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.
