When evaluating the quality of lever chain hoists (i.e. lever chain hoists), a comprehensive evaluation should be conducted from six core dimensions: structural integrity, functional performance, safety devices, key component quality, environmental adaptability, and operational standardization. The following is a specific analysis:

1、 Structural integrity

Appearance inspection: Check whether the equipment has obvious deformations, cracks, or defects, which may affect the overall strength and stability of the equipment.

Surface treatment: Observe whether the surface treatment is uniform, whether there is oxidation, rust, etc., which can affect the durability and service life of the equipment.

2、 Functional performance

Load bearing capacity: Test the stability and balance of the equipment under different loads to ensure that it can withstand the rated load without deformation or damage.

Operational performance: Check whether the equipment's starting, stopping, walking, lifting and other actions are smooth, without any jamming or abnormal noise.

Operational flexibility: Evaluate the operability and response speed of the equipment to ensure that operators can easily control its movements.

3、 Safety device

Limit protection: Check whether the equipment is equipped with effective limit devices, such as rising limit devices, falling limit devices, etc., to prevent the equipment from exceeding the safe range during operation.

Braking system: Test whether the braking system of the equipment is sensitive and reliable, and can quickly stop the operation of the equipment in emergency situations.

Electrical safety: Check whether the electrical system of the equipment meets safety standards, such as whether the grounding and neutral connections are good, whether the electrical components are aging or damaged, etc.

4、 Quality of key components

Wire rope: Check whether the wire rope has broken wires, twists, wear or bending corrosion, which can affect the load-bearing capacity and service life of the wire rope.

Chain: Evaluate the degree of wear and connection of the chain to ensure that it will not break or fall off during operation.

Gears and bearings: Check the wear of gears and bearings to ensure they can operate smoothly and reduce noise and vibration.

Motor: Test the performance and stability of the motor to ensure that it can provide sufficient power to drive the equipment to operate.

5、 Environmental adaptability

Temperature adaptability: Test the operation of the equipment under different temperature conditions to ensure that it can work normally under extreme temperatures.

Humidity adaptability: Evaluate the corrosion resistance of equipment in humid environments to ensure that it will not be damaged due to high humidity.

Adaptability to air pressure and wind speed: For outdoor equipment, it is necessary to test its stability under different air pressure and wind speed conditions to ensure that it will not tip over or be damaged due to excessive wind.

6、 Operational standardization

Operator Qualification: Ensure that operators have the corresponding qualifications and training experience, are proficient in operating equipment, and comply with safety operating procedures.

Operation records: Check the operation and maintenance records of the equipment to understand its usage and maintenance status, in order to promptly identify potential problems and take measures to repair them.
