The lever chain hoist needs to take targeted preventive measures at different stages of use, which can be divided into four stages: before use, during use, after use, and long-term disuse:

1、 Preventive measures before use

Equipment inspection

Appearance inspection: Confirm that the crane casing has no cracks, deformations, or severe wear, and that key components such as hooks, chains, and brakes are not damaged.

Function test: Manually operate the lever to check if the chain is smooth and if the brake can effectively brake, ensuring no jamming or abnormal noise.

Safety device verification: Test safety functions such as limiters and overload protection devices to ensure their sensitivity and reliability.

Lubrication maintenance: Apply lubricating oil to moving parts such as chains and gears to reduce friction and wear.

Environmental Assessment

Site conditions: Ensure that the working ground is flat and solid, free of obstacles or loose objects, and avoid the crane tipping over.

Space restrictions: Check that there are no obstacles such as high-voltage lines or pipelines above the work area, and no personnel or equipment below.

Weather factors: Suspend operations in adverse weather conditions such as strong winds, thunderstorms, and high temperatures to prevent equipment damage or accidents.

Personnel preparation

Qualification confirmation: Operators must hold a certificate and be familiar with the crane operation procedures and emergency measures.

Safety training: Regularly organize safety training to strengthen operators' understanding of equipment performance, hazards, and protective measures.

Personal protection: Operators are required to wear protective equipment such as safety helmets, anti slip shoes, gloves, and safety belts during high-risk operations.

2、 Preventive measures during use

Standard operation

Load control: Strictly adhere to the rated load, prohibit overloading, and avoid chain breakage or equipment overturning.

Operating posture: Maintain body balance, avoid sudden force or pulling of the lever, and prevent equipment from losing control.

Signal communication: When multiple people are working, clarify the command signal to ensure consistency between operation and command.

real-time monitoring

Equipment status: During operation, closely monitor the operation of components such as chains, brakes, and hooks. If any abnormalities are found, immediately stop the machine for inspection.

Load state: Ensure stable load, avoid shaking or tilting, and prevent collision with surrounding objects or personnel.

Environmental changes: In case of sudden weather changes or changes in site conditions, immediately stop work and take safety measures.

emergency response

Fault response: Develop emergency plans and clarify the shutdown, evacuation, and reporting procedures in the event of a fault.

Emergency braking: When the risk of equipment loss of control or load falling is detected, immediately press the emergency braking button to cut off the power supply.

Personnel rescue: If personnel are trapped or injured, initiate rescue procedures, contact professional rescue teams, and protect the scene.

3、 Preventive measures after use

Equipment cleaning

Cleaning and maintenance: Remove oil, dust, and debris from the surface of the equipment to prevent corrosion or wear.

Chain storage: Organize the chains neatly to avoid entanglement or knotting, and extend their service life.

Component fixation: Check whether the connections of each component are firm to prevent loosening or detachment.

regular maintenance

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

Component replacement: Timely replace severely worn components such as chains, hooks, brake pads, etc. to ensure equipment safety.

Functional testing: Regularly conduct comprehensive functional testing to verify whether the device performance meets the standards.

Record and archive

Usage record: Detailed record of equipment usage time, load, operator and other information for easy traceability and analysis.

Maintenance records: Record maintenance time, content, replacement parts, and other information to provide a basis for equipment management.

Fault record: Record the phenomena, causes, and handling measures of equipment faults, summarize experiences and lessons learned, and improve preventive measures.

4、 Long term shutdown prevention measures

Equipment sealing

Clean and dry: After cleaning the equipment, store it in a dry and ventilated room to avoid moisture or corrosion.

Component protection: Apply rust proof oil to components such as chains and hooks to prevent rusting or corrosion.

Fixed storage: Fix the equipment on a dedicated bracket or ground to prevent tipping or collision.

regular inspection

Startup testing: Before restarting after long-term disuse, conduct a comprehensive inspection and functional testing to ensure the normal operation of the device.

Component replacement: Replace aging or damaged components in a timely manner to avoid working with defects.

Lubrication maintenance: Supplement lubricating oil to moving parts to reduce wear during startup.

personnel training

Retraining and assessment: Retrain and assess personnel who have not operated equipment for a long time to ensure they are familiar with operating procedures and safety requirements.

Emergency drill: Organize emergency drills to improve the ability of operators to respond to emergencies.
