When using a chain hoist in underground environments, the following key issues need to be noted to ensure the safety, efficiency, and reliability of the operation:

1、 Preparation before operation

Professional training: Operators must undergo professional training and hold relevant certificates, familiarize themselves with the operating procedures of chain hoists and the special requirements of underground operations.

Equipment inspection: Before operation, a comprehensive inspection of the chain hoist must be carried out to ensure that the power supply, controller, chain and other components are intact, without rust or looseness, and that the bearing capacity meets the design requirements.

Safety equipment: Operators must wear personal protective equipment such as safety helmets, safety shoes, gloves, etc. to prevent potential injury risks.

2、 Precautions during operation

Environmental observation: When working underground, special attention should be paid to changes in the surrounding environment to ensure that there are no personnel or obstacles hindering the operation. At the same time, attention should be paid to the ventilation of the underground space to avoid the accumulation of harmful gases.

Caution in operation: During the operation, it is necessary to remain vigilant and avoid sudden acceleration or deceleration. Adjust the height and speed of the hoist according to actual needs.

Prohibition of illegal operations: It is forbidden to insert hands or other objects into the operating area of the elevator to avoid injury. If any abnormal situation is found, such as abnormal noise, vibration, etc., the machine must be stopped immediately for inspection and forced use is not allowed.

3、 Equipment maintenance and upkeep

Regular lubrication: The chain and transmission components of the chain hoist need to be lubricated regularly to prevent damage caused by dry grinding. In underground environments, due to high humidity, lubrication should be given more attention.

Cleaning and maintenance: Timely remove dust and foreign objects on the chain plate, keep the equipment clean, and reduce additional wear and tear. At the same time, pay attention to checking whether the chain and connecting parts have wear, cracks, or deformation issues.

Shutdown treatment: When not in use for a long time, unload the materials and apply anti rust oil to protect the chain. Store in a dry and ventilated place to prevent rust and damage.

4、 Other precautions

Power safety: Before use, it is necessary to check whether the power supply meets the requirements and ensure that it is operated according to electrical specifications to avoid electrical safety accidents.

Emergency plan: Develop and familiarize oneself with emergency response measures and plans in case of emergencies, so as to be able to quickly and effectively handle them in case of accidents.

Compliance: Ensure that the use of chain hoists complies with relevant laws, regulations, and industry standards, avoiding risks and liabilities caused by unauthorized operations.
