The applicable specifications for lever chain hoist cover ten core areas: equipment selection, manufacturing license, installation and modification, registration of use, personnel qualifications, safe operation, maintenance, safety devices, environmental requirements, and emergency management. The following are specific explanations:

1、 Equipment selection specifications

Select the appropriate model based on the load frequency and environmental conditions (such as corrosiveness, high temperature, dust, etc.) of the usage scenario. For example, in the metallurgical industry, high-temperature resistant and explosion-proof equipment should be selected, and rust prevention treatment should be strengthened in humid environments.

2、 Manufacturing License Requirements

The equipment must be produced by units with corresponding manufacturing qualifications, and the products must be certified by safety technical specifications, accompanied by quality certificates, installation and use instructions, and supervision and inspection certificates.

3、 Installation and renovation specifications

Installation, renovation, and major maintenance must be carried out by certified units and subject to supervision and inspection. After construction, concealed engineering records, quality certificates, and supervision and inspection reports must be provided.

4、 Use registration system

The user unit needs to register the equipment before it is put into use, submit product technical information, installation quality certificates and other documents, and obtain the registration certificate before it can be operated.

5、 Personnel qualification management

Operators must undergo professional training and obtain the "Special Equipment Operator Certificate", be familiar with the equipment structure, principles, and control technology, strictly follow operating procedures, and prohibit unlicensed operations.

6、 Safety operating procedures

Pre operation inspection: Confirm that the brake, hook, wire rope, and safety device are in normal condition, and only start after troubleshooting.

Load limit: Overloading operation is strictly prohibited. When lifting heavy objects close to the rated capacity, a trial lifting must be conducted.

Environmental safety: Ensure that there are no obstacles in the work area, no personnel stay on the lifting route, and avoid working in dangerous areas such as high-voltage lines and pipelines.

Operation specifications: Do not pull or suspend diagonally, suddenly apply force or forcefully pull the lever, and maintain equipment stability during operation.

7、 Maintenance requirements

Daily inspection: Regularly check the wear and tear of components such as brakes, chains, and hooks, and replace damaged parts in a timely manner.

Lubrication and maintenance: Regularly lubricate moving parts such as chains and gears to reduce wear and tear.

Professional maintenance: Develop maintenance plans and have professional personnel conduct comprehensive inspections and maintenance of equipment to ensure that safety devices are sensitive and reliable.

8、 Requirements for safety devices

The equipment should be equipped with safety facilities such as limiters and overload protection devices, and their effectiveness should be regularly verified. For example, when the lifting height exceeds 6 meters, an overspeed protection device needs to be installed.

9、 Environmental adaptability requirements

When used in harsh environments such as high temperature, humidity, and corrosiveness, protective measures (such as anti rust coatings, high-temperature resistant materials, etc.) should be taken, and equipment inspection frequency should be strengthened.

10、 Emergency Management Standards

Develop emergency plans and clarify processes such as shutdown due to malfunctions and personnel rescue. Operators need to be familiar with emergency measures. In case of equipment loss of control or risk of load falling, immediately press the emergency brake button and initiate rescue procedures.
