Precautions and safety specifications for operating stainless steel lever hoist

1、 Equipment inspection and maintenance

Daily inspection

Load chain and hook: Before operation, check whether the load chain is intact, without cracks, deformations, or corrosion; The hook should have a safety lock to avoid the risk of detachment (refer to Jiali Machinery product description).

Braking system: Confirm the sensitivity and reliability of the brake, and verify the automatic inertia brake during no-load and load tests (ASME B30.21 standard).

Handle and operating mechanism: Check if the handle can rotate 360 ° without any obstruction to ensure flexible operation (refer to Ingersoll Rand design).

Stainless steel material maintenance

Anti corrosion treatment: Regularly clean the surface of the equipment to avoid corrosion caused by salt spray, chemicals, or humid environments. Anti rust lubricants can be used to maintain seals and bearings (refer to OSHA equipment maintenance requirements).

Coating protection: If Ni-P alloy coating is used, the integrity of the coating should be checked regularly (refer to anti-corrosion research literature).

Load Testing

After new equipment or maintenance, a 1.5 times rated load test is required to ensure the reliability of the braking system (ASME B30.21 standard).

2、 Operating standards

Load limit

Overloading is strictly prohibited. It is necessary to confirm that the rated load (such as the 6-ton model) matches the actual load (refer to TXK product parameters).

The load should be evenly distributed to avoid equipment overload caused by skewing.

operating environment

Avoid using in corrosive or humid environments. If necessary, choose stainless steel material and strengthen protection (refer to Ingersoll Rand anti-corrosion design).

Explosion proof models (refer to Qingdao Welldone explosion-proof products) should be used in flammable and explosive environments.

Handle operation

Keep the handle dry during operation to avoid slipping. When rotating the handle 360 °, ensure that there are no obstacles around (ASME B30.21 standard).

3、 Security measures

brake system

Automatic inertia braking should brake smoothly when the load drops to avoid impact caused by rapid descent (refer to Jiali Machinery brake design).

Regularly check the wear of brake pads and replace them in a timely manner.

Emergency Management

If any abnormalities are encountered during operation (such as abnormal noise or jamming), immediately stop and inspect to avoid forced operation (OSHA safety regulations).

In emergency situations, manual release devices must follow the manufacturer's operating instructions.

Corrosion prevention and protection

Stainless steel components need to be cleaned regularly to avoid chemical substances from adhering (refer to anti-corrosion research literature).

Confirm the operating temperature range of the equipment in high or low temperature environments (refer to ASME environmental adaptability requirements).

4、 Compliance with regulations and standards

OSHA/ANSI standards

Compliant with OSHA 1910.179 (bridge crane), ASME B30.21 (lever hoist safety standard) and other specifications.

The equipment needs to have CE, ISO and other certifications (refer to TXK product certification).

Record and Inspection

Regularly record equipment inspection, maintenance, and testing data and retain it for at least one year (OSHA record keeping requirements).

Establish equipment files to record the results of each maintenance and inspection.

5、 Special environmental precautions

Explosion proof requirements

When used in flammable and explosive environments, explosion-proof models must be selected and electrical components must comply with explosion-proof standards (refer to Qingdao Welldone products).

High/low temperature environment

Under extreme temperatures, it is necessary to confirm the temperature resistance of equipment materials to avoid aging of plastic or rubber components (refer to ASME environmental adaptability clauses).

6、 Example of Operation Process

Before operation

Check the appearance of the equipment, load chain, hook, and braking system.

Confirm that the load does not exceed the rated value and the working environment is free of corrosive substances.

in operation

Slowly operate the handle to avoid impact caused by rapid lifting.

Ensure that the brake is fully locked when the load is hovering.

After operation

Clean the surface of the equipment and apply rust inhibitor.

Store the equipment in a dry and ventilated place, avoiding humid environments.
