Appearance inspection

• Check the hook surface for cracks, deformation or wear (pay special attention to the hook mouth, hook neck and threaded part).

• Make sure the anti-unhooking device (such as spring lock) is intact and effective to prevent the sling from accidentally slipping off.

• Check whether the hook rotates flexibly and without sticking.

Labeling and Certification

• Make sure there is a clear load rating mark on the hook and overloading is strictly prohibited.

• Check whether the hook has the manufacturer's certificate of conformity or periodic inspection mark.

Matching parts inspection

• Check whether the connection between the hook and the wire rope, chain or sling is firm (such as whether the nut and pin are tightened).

• Check whether the pulleys, bearings and other parts are well lubricated.

Preparation before lifting

• Select the appropriate hook type (such as single hook, double hook, swivel hook, etc.) according to the weight, shape and center of gravity of the object being hoisted.

• Ensure that the slings (wire ropes, slings, etc.) are hung symmetrically at the center of the hook to avoid unbalanced loading.

• The hook opening should face outward (away from the object being hoisted) to prevent the wire rope from falling out.

Hooking Techniques

• Anti-unhooking measures : Always use anti-unhooking devices; if there is no lock, the sling can be fixed with wire or special clips.

• Avoid shock loads : Lift slowly and avoid sudden acceleration or emergency stops to prevent the hook from being subjected to additional impact force.

• Multi-hook collaborative operation : When using multiple hooks, ensure that the load is evenly distributed and be directed and coordinated by a dedicated person.

Precautions during lifting

• Keep the suspended object stable to avoid swaying or rotation that may cause uneven force on the hook.

• It is prohibited for people to stand under the suspended objects or pass under the hook.

• It is prohibited to use a hook to directly drag objects on the ground (such as pulling at an angle or hard) to avoid damaging the hook mouth.

Avoid hook overload

• The sling should be hung at the bottom of the hook (the center of force), not the tip or side of the hook (which can easily cause deformation).

• Example: If double hooks are used, the angle between the two slings should not exceed 60°, otherwise the load needs to be reduced.

Special scene processing

• High temperature environment : Avoid exposing the hook to high temperature for a long time to prevent the strength of the material from decreasing.

• Corrosive environment : clean promptly after use and apply anti-rust grease.

Signaling and Communication

• Strictly follow the signals from the commander and stop operating immediately when the signals are unclear.

• Use intercoms or hand gestures to communicate clearly and avoid misoperation.

Cleaning and Storage

• Remove debris (such as cement, oil) from the hook to prevent corrosion or jamming.

• Store in a dry environment, away from moisture or chemical corrosion.

Periodic inspection and scrapping standards

• Daily Inspection : Quickly check appearance and flexibility before work.

• In-depth inspection : Measure the hook mouth wear (if it exceeds 10% of the original size, it will be scrapped) or deformation (such as the hook body bending more than 10°) every month.

• Mandatory scrapping : If cracks, severe rust or thread damage occur, the machine must be replaced.
