When using a stainless steel lever crane, strict control is required from multiple aspects such as safe operation, equipment maintenance, and environmental adaptation to ensure operational efficiency and personnel safety. The following are key precautions and practical suggestions:

1. Safety operation standards

Avoid overloading:

Strictly follow the rated load indicated on the equipment nameplate and prohibit overloading. Overloading may cause chain breakage, hook deformation or structural damage, and even lead to accidents.

Case reference: A factory caused a chain breakage due to overloading of a crane, resulting in the fall of goods and injuries to personnel.

Correct operation of the joystick:

When operating, keep the handle parallel to the ground to avoid lateral force or excessive bending of the chain. Sudden release of the handle may cause the load to lose control, and it should be slowly released to control the descent speed.

Load stability:

Ensure even distribution of load and avoid lateral loads or inclined lifting. Before use, check if the lifting point is secure and use auxiliary ropes to fix the load if necessary.

2. Regular inspection and maintenance

Chain and hook inspection:

Before each use, check whether the chain has cracks, deformations, or rust, and whether the hook head is worn or deformed. Replace components immediately upon discovering abnormalities to avoid working with defects.

Case reference: A chemical enterprise failed to replace the worn hook head in a timely manner, resulting in the hook head breaking during the lifting process.

Braking system testing:

Regularly test the braking performance to ensure that the load can reliably stop at any position. If the brake fails, it should be immediately stopped and sent for repair.

Lubrication and rust prevention treatment:

Although stainless steel material is corrosion-resistant, moving parts such as chains and gears still require regular lubrication (using corrosion-resistant lubricants). In humid or salt spray environments, it is necessary to increase the frequency of cleaning and rust prevention.

3. Environmental adaptability adjustment

Extreme environmental protection:

When used in high salt spray, chemical corrosion, or high temperature environments, it is necessary to choose higher specification stainless steel materials (such as 316L) and install protective covers or coatings.

Case reference: Due to the lack of salt spray protection for the crane on a certain offshore platform, the chain quickly corroded.

Temperature impact:

Stainless steel may become brittle in low temperature environments, and severe impact should be avoided; In high temperature environments, it is necessary to confirm the temperature resistance level of the material (such as molybdenum containing stainless steel that can withstand higher temperatures).

4. Load management and storage

Load assessment:

Accurately evaluate the load weight and center of gravity position before lifting to avoid equipment overload caused by estimation errors. Use a force gauge or weighing device to assist in confirmation.

Storage specifications:

Store in a dry and ventilated room, avoiding contact with corrosive substances. When stored for a long time, anti rust oil should be applied to components such as chains and covered with protective cloth.

5. Personnel training and compliance

Operation qualification:

Operators need to receive professional training and be familiar with equipment performance and emergency response procedures. Unauthorized personnel are prohibited from operating.

Compliance certification:

Select products that comply with international standards (such as EN 13157, ASME B30.16) and local regulations (such as CE certification, OSHA specifications) to ensure equipment safety and legality.

6. Emergency response and recording

Accident plan:

Develop emergency plans for lifting accidents, including response measures for scenarios such as load slippage and equipment failure. Regularly conduct drills to enhance emergency response capabilities.

Maintenance records:

Establish equipment usage and maintenance records, recording the time and content of each inspection, repair, and replacement of components, to facilitate tracking of equipment status and accountability.
