Precautions During the Use of a Lifter
A lifter, also known as an elevating device or lifting equipment, is widely used in industrial production, construction, warehousing, logistics, and maintenance operations. It plays a crucial role in raising heavy objects to a desired height, improving efficiency, and reducing manual labor. However, improper use of a lifter can lead to serious safety accidents, equipment damage, or personal injury. Therefore, understanding and strictly following safety precautions during the use of a lifter is essential. The following points outline key considerations to ensure safe and effective operation.
1. Pre-Use Inspection
Before operating a lifter, a comprehensive inspection must be carried out. The operator should check whether the structure of the lifter is intact, including the frame, lifting platform, hydraulic system, chains, screws, and fasteners. Any signs of deformation, cracks, oil leakage, abnormal noise, or loose components should be addressed immediately. Electrical lifters should be inspected for damaged cables, loose connections, and proper grounding. Operating a lifter with existing faults is strictly prohibited, as minor defects can quickly escalate into serious accidents under load.
2. Load Capacity Awareness
Every lifter has a rated load capacity specified by the manufacturer. Exceeding this limit is one of the most common causes of lifter failure. Operators must clearly understand the maximum load and ensure that the weight of the object being lifted, including any additional tools or fixtures, does not exceed the rated capacity. Overloading can cause structural damage, hydraulic system failure, or sudden collapse, posing a severe risk to personnel and equipment.
3. Proper Placement and Stability
The lifter must be placed on a solid, flat, and stable surface before use. Uneven or soft ground can cause the lifter to tilt or sink, increasing the risk of instability during lifting. If necessary, support pads or base plates should be used to improve stability. Additionally, the object being lifted should be positioned centrally on the lifting platform to ensure even load distribution. Off-center loading can lead to imbalance, tipping, or excessive stress on specific components.
4. Correct Operating Procedures
Operators should be trained and authorized before using a lifter. During operation, all actions should be performed smoothly and steadily. Sudden lifting, rapid lowering, or abrupt stops should be avoided, as they can generate strong impact forces on the equipment. The operator should maintain constant attention and never leave the lifter unattended while it is in operation. Control buttons, levers, or switches must be used according to the manufacturer’s instructions, and emergency stop functions should be tested regularly.
5. Personnel Safety and Area Control
Ensuring the safety of personnel is a top priority when using a lifter. No one should stand under or near the load while it is being lifted or lowered. Warning signs or safety barriers should be set up around the operating area to prevent unauthorized access. Operators should wear appropriate personal protective equipment (PPE), such as safety helmets, gloves, and protective footwear. Clear communication should be maintained among team members, especially in environments where multiple workers are involved.
6. Environmental Considerations
Environmental conditions can significantly affect the safe use of a lifter. Strong winds, rain, snow, or poor lighting can reduce stability and visibility, increasing the risk of accidents. In outdoor operations, lifting should be suspended under adverse weather conditions. In indoor environments, adequate lighting and ventilation should be ensured. Additionally, lifters should not be used in corrosive, explosive, or high-temperature environments unless they are specifically designed for such conditions.
7. Maintenance and Regular Servicing
Routine maintenance is essential for ensuring the long-term safe operation of a lifter. Lubrication, cleaning, tightening of fasteners, and replacement of worn parts should be carried out according to the maintenance schedule. Hydraulic oil levels and quality should be checked regularly, and filters should be replaced as required. Any abnormal conditions discovered during operation should be reported and repaired promptly. Regular professional inspections can help identify hidden risks and prevent unexpected failures.
8. Shutdown and Storage
After use, the lifter should be lowered to its lowest position and powered off properly. Loads should never be left suspended for long periods. When not in use, the lifter should be stored in a dry, clean, and secure location to prevent corrosion and unauthorized operation. Proper storage extends the service life of the equipment and reduces the likelihood of damage.
Conclusion
The safe use of a lifter depends on strict adherence to operating procedures, awareness of load limits, proper maintenance, and a strong sense of responsibility among operators. By paying close attention to these precautions, users can significantly reduce safety risks, protect personnel, and ensure efficient and reliable lifting operations. Safety should always be the top priority, as no level of efficiency can justify compromising human life or equipment integrity.
