Stainless steel lever hoist application plan

1、 Material and Scene Adaptation Plan

material selection

304 stainless steel: suitable for humid or corrosive environments such as food processing plants, pharmaceutical factories, ocean ports, chemical sites, etc.

201/316 stainless steel: Choose according to air humidity and corrosion strength, such as 201 for arid areas and 316 for high salt spray or chemical environments.

Aluminum alloy material: suitable for high-altitude operations (such as power line construction) or scenes that require anti magnetic environment.

Industry application scenarios

Chemical and marine environment: Made of 316 stainless steel material, regularly treated for corrosion resistance.

Food and pharmaceutical industry: Ensure equipment is clean, wipe off dirt after use, and store in a dry location.

In the field of architecture and engineering, aluminum alloy materials are used in conjunction with magnetic environments to avoid magnetic field interference.

2、 Operating standards and safety plan

Rated load management

Overloading is strictly prohibited, and it is necessary to confirm that the weight of the chain hoist does not exceed the rated lifting capacity.

The lifting chain shall not be used as a lifting belt to avoid twisting, knotting, or single strand use.

Environmental adaptability operation

When used in a tilted or horizontal direction, adjust the zipper direction to conform to the sprocket and prevent it from slipping or getting stuck.

When multiple gourds work together, a dedicated person commands synchronous lifting.

Emergency response process

When using a chain, it is necessary to cushion the heavy object before conducting maintenance.

Immediately stop the machine for inspection upon discovering abnormal hand pulling force to prevent damage to the internal structure.

3、 Maintenance Plan

Daily inspection

Before use: Check whether the external and internal accessories (such as lifting chains, gears, bearings) are intact, and whether the lifting chain is twisted or knotted.

In use: Lubricants should be added to worn parts such as gears and bearings at any time.

After use: Clean the surface dirt, apply anti rust oil, and store in a dry place.

Regular maintenance

Cycle: Daily inspection before each shift, comprehensive inspection every month, and in-depth maintenance by professional personnel every year.

Key components:

Crane chain: Replace immediately if the wear exceeds 10%.

Brake: Adjust the clearance to ensure reliable braking; Friction plate wear exceeds the limit and needs to be replaced.

Gears and bearings: Supplement lubricating grease and promptly inspect in case of abnormal noise.

Electrical system: Check for circuit aging and poor contact, test limiters and emergency stop functions.

Record and Archive

Record each inspection, maintenance, and replacement of components, establish equipment files for easy traceability.

4、 Scrap disposal plan

Scrap standard

The main structure is severely corroded and deformed, and cannot be repaired.

Key components such as hooks and chains are worn out beyond the limit or broken.

The maintenance cost exceeds 50% of the original value, or upgrading is uneconomical.

Reaching the design service life (usually 5-10 years).

Process flow

Application and approval: Submit a scrap application, and after technical and economic evaluation and management approval, revoke the ledger.

Identification and isolation: Scrap equipment must be marked with a "disabled" label and stored separately.

Recycling and cancellation: Entrust professional institutions to recycle and avoid accidents caused by misuse of components; Update equipment ledger and cancel scrapped equipment information.

5、 Special environment and industry adaptation

Chemical Industry and Marine Environment

Use 316 stainless steel material and undergo regular anti-corrosion treatment.

Avoid using in strong magnetic field environments to prevent electrical faults.

Food and Drug Industry

Ensure the equipment is clean, wipe off any dirt after use, and store in a dry location.

Regularly carry out rust prevention treatment to prevent product contamination.

In the field of architecture and engineering

Use aluminum alloy material in conjunction with magnetic environment to avoid magnetic field interference.

When multiple gourds work together, they are commanded by a dedicated person and lifted synchronously.

6、 Training and Continuous Improvement

Operator training

Regularly conduct training on safety operating procedures to ensure that personnel are familiar with equipment performance and emergency response procedures.

The training content includes: safe operation, maintenance techniques, troubleshooting, etc.

Plan evaluation and improvement

Evaluate the plan annually, check the overall condition and maintenance effectiveness of the equipment.

Optimize maintenance plans based on evaluation results and introduce new technologies or materials to enhance equipment performance.
