For the protection and placement methods of completed electric hoists (especially explosion-proof electric hoists), the following are some key points, summarized and summarized based on the relevant figures and information in the reference article:

1. Precautions for placement

Stability: The explosion-proof electric hoist should be placed on a stable ground to avoid tilting or shaking, which may cause accidents.

Drying: It should not be placed in a damp place to avoid moisture affecting the normal operation of the equipment.

Ventilation: It needs to be placed in a well ventilated location to eliminate exhaust gases. If there is any odor during use, it is necessary to check in a timely manner to ensure the normal use of the equipment.

Easy to operate: The placement position also needs to ensure that the staff can operate the equipment conveniently, avoiding negligence and safety accidents during operation. Therefore, it is recommended to place the explosion-proof electric hoist closer to the workplace.

2. Usage and maintenance requirements

Running in and testing: Newly installed electric hoists should undergo running in and testing, including dynamic load tests with 10% rated load and excess load, as well as static load tests with 25% additional constant load.

Lubrication requirements: Ensure that the equipment has sufficient lubricating oil, and the lubricating oil should be clean and free of impurities and dirt. For different lubrication points, such as reducers, steel wire ropes, hook pulley bearings, etc., it is necessary to apply or add lubricants regularly.

Safe operation: Operators should receive training and guidance in advance and comply with relevant usage regulations. Avoid diagonal lifting or use as a horizontal towing tool, and do not allow lifting of buried objects.

3. Protection and storage methods

Avoid prolonged load suspension: After using the explosion-proof electric hoist, it is prohibited to suspend it in the air for a long time to prevent irreversible deformation of the parts.

Designated storage location: After use, it should be stopped at the designated location and the hook should be raised to a height of more than 2 meters above the ground.

Dry and ventilated environment: If it is determined that the explosion-proof electric hoist will not be used for a short period of time, it is necessary to store it in a dry and ventilated room.

Comprehensive inspection and cleaning: After use, a comprehensive inspection should be conducted to remove foreign objects and impurities, ensuring that the inside of the gourd is clean and tidy.

4. Protection in humid environments

Timely protection: After using in a humid environment for a period of time, wipe off moisture in a timely manner to prevent water from entering the interior of the electric hoist.

Pay attention to usage time: Avoid prolonged use in humid environments to reduce damage from moisture to the equipment.

Tool handling: In high humidity conditions, tools such as a hair dryer can be used to dry the surface of the equipment.
