How to Use a Clevis Grab Hook
Inspection Before Use
Before you start any job, you need to know how to use a clevis grab hook the right way. Inspection is your first step. You want to make sure your clevis grab hooks are safe and ready for action. Here’s what you should look for every time:
- Check all new, repaired, or modified hooks before you use them. This keeps you in line with ASME B30.10 standards.
- Watch for worn or damaged slings. If you see missing or unreadable tags, stop and replace them.
- Look for bent or deformed hardware. If the throat opening is spread more than 5%, the hook can’t safely hold its rated load.
- Search for cracks, nicks, gouges, or any sign of wear. If you spot these, remove the hook from service.
- Inspect hooks used in frequent load cycles with special methods like Magnetic Particle or Dye Penetrant testing.
- Never use hooks that have been welded, heated, or bent for repairs.
You should inspect your clevis grab hooks often. If you use them every day, check them daily or weekly. For normal jobs, a monthly inspection works. For heavy-duty work, inspect them weekly or monthly. Always do a full inspection at least once a year. If you find anything wrong, take the hook out of service right away.
Tip: Clean your chains before inspection. Dirt can hide damage and make it hard to spot problems.
Proper Attachment Steps
Knowing the proper way to use a grab hook makes your job safer and easier. Here’s a step-by-step guide on how to use a clevis grab hook for load securement:
- Choose the right hook for your job. Clevis grab hooks are perfect for chain shortening and load securement. Make sure you pick the right size and type.
- Select the correct chain. Powerful Machinery’s clevis grab hooks work best with Grade 43 chains. Always match the chain grade and size to the hook.
- Position the hook so the load sits in the bowl or saddle, not on the tip. This helps prevent bending or damage.
- Attach the chain by sliding the last link into the hook’s opening. The clevis pin and bolt system on Powerful Machinery hooks gives you a secure fit.
- Check the angle of your hitch. Use vertical, choker, or basket hitches depending on your load.
Note: Different chain grades have different working load limits. Grade 70 chains can handle about 20% more than Grade 43. Higher grades like 80, 100, or 120 offer even more strength and resistance to wear.
Here’s a quick table to help you match your clevis grab hook to the right chain:
| Chain Grade | Hook Throat Diameter | Clevis Pin Diameter |
|---|---|---|
| 43 | Match with size | Match with size |
| 70 | Match with size | Match with size |
| 80 | Match with size | Match with size |
| 100 | Match with size | Match with size |
Always follow the manufacturer’s guidelines for maximum load capacity. Powerful Machinery’s clevis grab hooks are tested to meet strict standards, so you can trust them for tough jobs.
Load Handling and Chain Shortening
