You chose a chain block 5 ton × 10 meter because the job demands high capacity with long reach, yet safety depends on much more than the headline numbers. You need to read the nameplate correctly, confirm the chain grade and number of falls, check prooftest data, and size hooks and trolleys so nothing binds overhead. This technical guide walks you through every checkpoint—standard compliance, load chain configuration, headroom, handpull, and routine inspection—so your 5 t, 10 m manual hoist runs smoothly from day one.

1) Decode the Nameplate on a Chain Block 5 Ton × 10 Meter

Look for these mandatory fields (per EN 13157 / ASME B30.16):

l WLL (Working Load Limit): 5 t

l Rated lift (H): 10 m

l Falls of load chain: typically 2 for a 5 t model

l Load chain grade & diameter: e.g., G80, 10 mm

l Proof test info and serial number

l Standard references (EN 13157, ASME B30.16, or equivalent)

If any of these are missing or unreadable, tag the hoist “out of service” until you verify the paperwork.

2) Load Chain Configuration: Grade, Diameter, and Falls

Most 5 t manual blocks reach capacity using two falls of Grade 80 (or Grade 100) chain. The double fall halves the tension per strand and lets you keep a manageable 10 mm diameter. Always confirm that the hook, pocket wheel, and suspension frame are rated for the combined load path.

Typical Chain Data (Reference Values)

Tip: The chain stamp should show “8” or “G80” (or higher). If you read G70, that chain is for tiedown, not lifting.

3) Brakes and Overload Protection

A 5 t × 10 m hand chain block normally uses a Westontype mechanical load brake with double pawls to hold the load if a pawl or spring fails. Many modern units also add a torquelimiting overload clutch that slips before structural parts yield. Test the brake engagement at ~125 % WLL during commissioning (per your local code) and log the result.

4) Headroom, Hook Throat, and Trolley Fit

A long lift does not guarantee enough headroom. Measure:

l Headroom (Hmin): distance from the top hook saddle to the bottom hook saddle at fully raised position.

l Hook throat opening: must be ≥ 4 × chain diameter to avoid pinch.

l Master link / suspension eye width: must fit your crane hook including safety latch.

l Trolley beam range: ensure the push or geared trolley spans your beam flange width and wheel profile.

Quick Geometry Table (Typical for 5 t Models)

*Adjust the hand chain loop length so operators pull without stooping or climbing.

5) HandPull and Ergonomics

Manual standards (e.g., EN 13157) limit the maximum handpull to keep operations ergonomic. A wellbuilt chain block 5 ton × 10 meter should keep required handpull near < 350 N at full load, with smooth, repeatable travel per pull. During acceptance, measure the pull with a spring scale to confirm it meets the data sheet.

6) Environmental Fit: Coating or Stainless?

l General indoor use: blackoxide or phosphate G80 chain works well.

l Outdoor or coastal yards: zincnickel coated G80 chain delays red rust and reduces cleaning intervals.

l Food / chemical / washdown zones: 304 or 316 stainless load chain and hooks avoid paint flakes and resist aggressive cleaning chemicals.

Choose the chain material for the environment and verify that braking surfaces and pawl components also suit the same conditions.

7) Routine Inspection—5 Minutes That Save Hours

Before each shift:

1. Tag check: WLL, lift, serial number clear and legible.

2. Chain condition: no twist, no nicks, no visible stretch; pitch uniform.

3. Hooks: latch closes and springs back; no throat spread, no cracks at saddle.

4. Hand chain path: clean, freerunning, no kinks.

5. Brake click test: raise a few centimeters, release; load stays locked.

Periodic inspection (e.g., quarterly or semiannually) should include a prooftest to 1.5 × WLL (or as your code specifies), a teardown of the brake pack, and a dimensional check of the hook and chain.

8) Documentation You Should Keep with Every 5 t × 10 m Hoist

l Declaration of conformity / test certificate to EN 13157 / ASME B30.16

l Prooftest report showing load, duration, and unit serial number

l Maintenance log (inspections, replaced parts, brake adjustments)

l Traceability IDs for load chain (heat/batch number) and hooks

Without this paperwork, audits stall and site rules may block the hoist from service.

Image Guide

1. Load chain closeup: confirm “8” or “G80” stamp every few links.

2. Brake pack opened: double pawls and friction discs clean and intact.

3. Hook gauge check: caliper across hook throat to verify no spread.

4. Trolley fitment: 5 t block mounted on a geared trolley with correct beam spacing.

FAQ (Focused on 5 t × 10 m Models)

Q: Can I run a singlefall chain on a 5 t block?
Most manual blocks hit 5 t with two falls; singlefall designs typically need a thicker chain or different gearing. Always follow the manufacturer’s configuration.

Q: How often do I prooftest a chain block 5 ton × 10 meter?
Follow your jurisdiction’s rule (commonly annually or after any suspected overload) and the manufacturer’s instructions—typically 1.5 × WLL for hoists.

Q: Can I lift personnel?
ASME B30.16 and EN 13157 do not allow manual chain blocks for lifting people unless the hoist is specially designed and certified for manriding.

Q: What about extreme temperatures?
Above 200 °C, derate as per the data sheet. Below −20 °C, confirm lowtemperature impact toughness for hooks and chains.

Conclusion

Verify the nameplate, confirm twofall Grade 80 (or higher) load chain, check the brake and overload clutch, size the hooks and trolley correctly, and run the fiveminute inspection before every lift—do that and your chain block 5 ton × 10 meter will deliver safe, predictable performance shift after shift.
