7 Common Mistakes When Using a Manual Chain Hoist (Over 90% of lifting accidents are caused by improper use)

Manual chain hoists are widely used in construction, manufacturing, warehousing, and maintenance work.
However, field experience shows that more than 90% of manual chain hoist accidents are not caused by product defects, but by incorrect operation.

Below are 7 common and quantifiable mistakes that significantly increase the risk of failure and accidents.

Mistake 1: Overloading the Hoist (≈35% of serious accidents)

Typical behavior:

Using a 3-ton manual chain hoist to lift 4–5 tons
Ignoring dynamic load during lifting

Quantified impact:

Brake system load increases by 25–50%
Chain fatigue life reduced by over 60%
High risk of brake slipping or hook deformation

Even with G80 lifting chain (4:1 safety factor), overloading is strictly prohibited.

Mistake 2: Side Pulling or Non-Vertical Lifting (≈20%)

Typical behavior:

Hoist not positioned directly above the load
Pulling the hand chain at an angle

Quantified impact:

Chain and load wheel wear increases 2–3 times
Higher risk of chain jamming and uneven stress

Manual chain hoists are designed for vertical lifting only.

Mistake 3: Insufficient Suspension Point Strength (≈15%)

Typical behavior:

Hanging the hoist on scaffolding or thin beams
Not checking the WLL of the anchor point

Quantified impact:

Anchor point failure risk increases 3–5 times
Failures are often sudden and without warning

👉 The suspension point must be at least as strong as the hoist itself.

Mistake 4: Twisted or Misaligned Load Chain (≈10%)

Typical behavior:

Load chain twisted 180°
Chain not properly seated in the load wheel

Quantified impact:

Local stress on chain links increases by over 40%
Increased risk of jamming and abnormal wear

Mistake 5: Jerking the Hand Chain (≈8%)

Typical behavior:

Pulling the hand chain violently to lift faster
Applying sudden force repeatedly

Quantified impact:

Impact load on gears increases 1.5–2 times
Accelerated wear of braking components

Mistake 6: Using a Manual Chain Hoist for Continuous Lifting (≈7%)

Typical behavior:

Long, uninterrupted lifting operations
Replacing an electric hoist with a manual hoist

Quantified impact:

Brake overheating
Significant reduction in service life

Manual chain hoists are designed for intermittent lifting, not continuous operation.

Mistake 7: Lack of Inspection and Maintenance (≈5%)

Typical behavior:

Using rusty or dry chains
Ignoring worn hooks or safety latches

Quantified impact:

Increased risk of chain jamming
Reduced braking reliability

How to Use a Ручной цепной подъемник Safely

✔ Never exceed the rated load
✔ Lift vertically at all times
✔ Inspect hooks and chains before use
✔ Lubricate the load chain regularly
