Regarding the technical data, operating environment, and appearance requirements of electric chain cranes, as the direct information source is not complete in the provided reference article, I will provide a summary answer based on general knowledge of lifting equipment and possible industry standards, combined with some relevant information.

technical data

Capacity: The capacity of electric chain cranes can range from 1/8 ton (125 kg) to 5 tons (5000 kg), depending on different brands and models.

Lifting height: Standard lifting heights include 10 feet, 15 feet, and 20 feet, but additional lifting heights can also be provided as needed.

Speed: The speed of the crane may include single speed, double speed, or variable frequency control to adapt to different work requirements.

Power supply: Usually electric, it needs to be connected to an appropriate power source for power supply.

Structure: The frame is usually made of lightweight aluminum and is precision machined to ensure accurate alignment of gears and bearings.

Operating environment

Temperature: The crane should be operated within the temperature range specified by the manufacturer to avoid performance degradation caused by overheating or low temperatures.

Humidity: High humidity environments may cause corrosion or short circuits in electrical components, so use under extreme humidity conditions should be avoided.

Dust and dirt prevention: In environments with high levels of dust or pollutants, the crane should be regularly cleaned to maintain its optimal performance.

Safety: When operating a crane, all safety regulations and procedures should be followed to ensure the safety of personnel and equipment.

Appearance related requirements

Coating: The surface of the crane should be coated with a corrosion-resistant and wear-resistant coating to provide long-term protection.

Identification: All necessary warning labels, operating instructions, and safety signs should be clearly visible and comply with relevant standards.

Visual inspection: Before each use, a visual inspection should be conducted to ensure that there are no damaged, worn, or missing components.

Cleaning: Regularly clean the crane to maintain its neat appearance and prevent the accumulation of dust and dirt.
