Safe Operating Procedures for Hand Chain Hoists in Coal Mine Production

As a common lifting tool, the hand chain hoist is widely used in coal mines, construction, and other industries. However, to ensure the safety of personnel, a series of strict safety measures must be implemented during use.  

Firstly, a thorough inspection of the hoist’s integrity must be conducted before each use. Any detected damage or malfunctions should be immediately replaced to prevent accidents during lifting operations. Additionally, critical components such as chains, gears, and brakes must be checked for flexibility and reliability to ensure safe operation.  

Secondly, the operating location should avoid unstable or slippery surfaces. Ideally, the hoist should be used on flat, solid ground. Appropriate models and quantities of hoists must be selected based on the load weight, ensuring they can bear the corresponding load. Overloading must be strictly prohibited to prevent equipment damage or personal injury.  

During actual operations, the following points should be noted:  

1. It is strictly forbidden to suspend the hoist below or above other equipment to avoid safety incidents caused by external interference.  

2. Prolonged suspension in the same position may lead to uneven stress and damage to the hoist. Adjustments or removal should be made promptly after use.  

3. When operating in rainy or snowy weather, anti-slip measures such as laying anti-slip mats must be taken to prevent slipping accidents.  

Timely cleaning and maintenance of the hoist after use are crucial. This not only extends its service life but also ensures safety for subsequent uses. Regular inspections and maintenance of critical components like chains, gears, and brakes should be conducted to guarantee optimal performance.  

When using hand chain hoists in coal mines, all relevant safety regulations and operating procedures must be strictly followed. This includes, but is not limited to, proper use of personal protective equipment, compliance with safety warning signs, and receiving professional training. Only through comprehensive safety measures can the safe use of hand chain hoists be ensured, safeguarding the lives and property of workers.
