When using a low clearance electric hoist, in order to ensure operational safety, extend equipment life, and improve work efficiency, the following key precautions should be followed:

1、 Pre use inspection

Equipment integrity check

Confirm that the appearance of the electric hoist is free of deformation, cracks, or rust, and focus on checking whether key components such as the hook, wire rope, and rope guide are intact.

Example: If the opening of the hook exceeds 10% of the original size or there are cracks, it needs to be replaced immediately.

Electrical system testing

Check if the cables are damaged, if the wiring is secure, and test the sensitivity of the remote control or control buttons.

Warning: Waterproof remote control should be used in humid environments to avoid the risk of short circuit.

Lubrication and trial operation

Add lubricating oil to moving parts such as gears and bearings, conduct a no-load test run for 3-5 minutes, and observe whether the operation is smooth and there is no abnormal noise.

2、 Operating standards

Overloading is strictly prohibited

Strictly adhere to the rated load (such as 1 ton, 2 tons, etc.), and prohibit illegal lifting by tying wire ropes or adding counterweights.

Data: Overloading by 30% can shorten the lifespan of steel wire ropes by more than 50%.

Standardize lifting operations

Before lifting the goods, it is necessary to ensure that the lifting point is stable and the lifting height does not exceed the set value of the limiter to avoid hitting the top structure.

Analogy: The lifting process is similar to "fishing line collection", which needs to be slow and steady, and it is forbidden to pull diagonally or forcefully.

Safe operation path

Clear obstacles on the track and maintain a safe distance (recommended ≥ 0.5 meters) from obstacles such as walls and equipment during operation.

Case: A factory derailed its electric hoist due to failure to clean up track debris, resulting in maintenance costs exceeding 20000 yuan.

3、 Environment and Maintenance

Environmental adaptability

Avoid using in environments with corrosive gases (such as acid mist), high temperatures (>60 ℃), or low temperatures (<-20 ℃).

Special scenario: The chemical workshop needs to use explosion-proof electric hoists and install protective covers.

Regular maintenance plan

Daily: Clean the equipment and check the wear of the steel wire rope.

Monthly: Lubricate moving parts and test brake reliability.

Every year: Entrust professional institutions to conduct comprehensive inspections and replace parts with excessive wear and tear.

Discontinue management

When not in use for a long time, cut off the power, park the electric hoist in the designated location, and cover it with a dust cover.

4、 Security protection

Personnel protection

Operators are required to wear safety helmets and gloves, and are prohibited from standing directly under the goods or working in the air.

Training: All operators must undergo professional training to familiarize themselves with the location of emergency stop buttons.

Equipment protection

Install safety devices such as overload limiters and travel limiters, and regularly verify their accuracy.

Warning: Disabling safety devices or adjusting limiter parameters without authorization is a serious violation.

5、 Emergency response

Fault response

If any abnormalities are found (such as abnormal noise or lagging), immediately stop the machine, hang a "Do Not Use" sign, and contact maintenance personnel.

Prohibition: Malfunctioning equipment should be operated with defects.

Accident contingency plan

Develop emergency plans for cargo falling and equipment loss of control, and regularly organize drills.

Data: Simulation exercises can improve accident handling efficiency by over 40%.

6、 Compliance and Records

Regulatory compliance

Comply with regulations such as the Special Equipment Safety Law, regularly report for inspection, and obtain a registration certificate for use.

Warning: Unauthorized use or failure to inspect beyond the deadline will result in high fines.

file management

Establish equipment archives to record maintenance, repair, and troubleshooting information, and achieve full lifecycle management.

Summary: The safe use of low clearance electric hoists requires coordinated protection from five aspects: equipment status, operating standards, environmental adaptation, maintenance, and emergency response. By strictly implementing the above measures, the risk of accidents can be significantly reduced, equipment lifespan can be extended, and production efficiency can be improved.
