To determine whether the explosion-proof electric hoist is in good operating condition, a comprehensive evaluation can be conducted from the following aspects:

1. Equipment appearance and structure

Appearance inspection: Observe the appearance of the explosion-proof electric hoist for cleanliness, damage, deformation, or corrosion. Especially check whether the explosion-proof shell is intact and whether the sealing is good to prevent explosive gases or dust from entering.

Structural inspection: Check whether the structure of each part of the electric hoist is complete, whether the fasteners are loose, whether the transmission mechanism is flexible, and whether there is no jamming phenomenon.

2. Lubrication condition

Good lubrication: Ensure that the lubrication system of the explosion-proof electric hoist is normal, with sufficient lubricating oil or grease and clean without impurities. For parts that require lubrication, such as chains, bearings, etc., regular inspections and supplementary lubrication should be carried out.

Implement the "five fixed" and "three-level filtration": namely, fixed personnel, fixed quality, fixed quantity, fixed point, regular, and three-level filtration from the oil receiving barrel to the fixed oil storage tank, from the oil storage tank to the oil pot, and from the oil pot to the lubrication part, to ensure the cleanliness of the lubricating oil.

3. Operational performance

Smooth and noise free operation: During start-up and operation, the explosion-proof electric hoist should be stable without vibration or abnormal noise. If there is noise or vibration, it may be a malfunction in the transmission mechanism or bearings and other components.

Good electrical insulation: Check the insulation performance of the electrical system to prevent electrical faults such as leakage or short circuit. At the same time, ensure that the electrical components of the electric hoist meet explosion-proof requirements.

Speed meets requirements: Check whether the operating speed of the electric hoist and the lifting speed of the hook meet the design requirements to ensure operational efficiency and safety.

4. Lifting capacity

Lifting capacity meets the standard: Ensure that the lifting capacity of the explosion-proof electric hoist reaches the output or rated capacity indicated on the nameplate. During normal use, avoid overloading to prevent equipment damage or safety accidents.

5. Safety protection device

Sensitive limit device: Check whether the limit device is sensitive and reliable, ensuring that it can automatically stop running when the hook is raised to the upper limit or lowered to the lower limit, to prevent accidents such as collision or decoupling.

Reliable braking: Ensure that the braking system is working properly and the braking is reliable without slipping. Can quickly brake and stop running in emergency situations.

6. Maintenance and upkeep

Regular maintenance and upkeep: Perform regular maintenance and upkeep work according to the manufacturer's maintenance manual or instructions, including cleaning, lubrication, tightening, inspection, etc. At the same time, record each maintenance and upkeep for future reference.
