Any individual sling or lifting equipment used to suspend the car or counterweight must be capable of carrying greater than 5 times the weight.
1. Weight-bearing capacity factors of suspension equipment
Equipment structural strength: The structural strength of suspension equipment is the key factor that determines its weight-bearing capacity. It requires sufficient material strength and reliability connection method.
Equipment working environment: The working environment of the suspension equipment will also affect its weight bearing capacity, such as temperature, humidity, corrosion and other factors that need to be taken into consideration. Scope of use and requirements: Different suspension equipment may have different requirements for use. For example, the load-bearing capacity of the elevator needs to meet the elevator load standards.
2. Specifications for the weight carrying capacity of suspension equipment
National standards: The country has corresponding standards and specifications for the safety requirements of suspension equipment, such as China GB/T15607-1995 "Wire Rope Crane" "wait. Manufacturer's Guide: Manufacturers of suspension equipment often provide detailed operating instructions and technical information, which include details such as the weight-carrying capacity of the equipment.
Engineering design calculations: For suspension equipment under special circumstances, such as large hanging towers, bridge cranes, etc., professional engineering design calculations are usually required and acceptance is carried out by relevant departments.
3. Weight bearing capacity calculation method
Static calculation: Calculate the maximum bearing capacity of the suspension equipment under static load through the strength of the material and structural design. Dynamic calculation: For suspension equipment such as lifting equipment that has a motion process, dynamic factors need to be considered for calculation, such as braking, acceleration, etc. Safety factor: In order to ensure the safety of suspension equipment, a safety factor is usually introduced in the calculation to ensure that the equipment has sufficient margin when it is actually used.
IV. Regular testing and maintenance of the weight-carrying capacity of suspension equipment
Regular testing: In order to ensure the safe operation of the suspension equipment, the weight-carrying capacity should be tested regularly, and problems should be repaired in a timely manner. Or replace the equipment. Maintenance: Routine maintenance of suspension equipment is very important. Regular lubrication, cleaning and inspection of various parts of the equipment can extend its service life.
In summary, the weight carrying capacity of the suspension equipment needs to be reasonably designed and calculated based on the actual situation. National standards, manufacturer's guidelines, and engineering design calculations are all important references for determining the weight-carrying capacity of suspension equipment. Regular inspection and maintenance can ensure the normal operation and safe use of suspension equipment. When using suspension equipment, relevant specifications and requirements should be strictly followed to ensure the safety of workers and the surrounding environment.
