An important step in the lifting operation of the sling sling is to determine the hoisting object and determine the center of gravity of the work. The most accurate method to obtain the weight data of the hoisting object is mainly the data provided. If there is no accurate information, other methods must be used to determine the weight, such as actual weighing or calculation.
1. How to determine the hoisting center of gravity of the sling sling, in order to ensure the lifting, before the operation, it is necessary to know where the gravity is, so as to accurately balance the load to the center. Easiest movement and no leaning if the weight is lifted directly above the center of gravity.
2. The weight of a target object is evenly distributed around the center of gravity. During the hoisting work, it should be ensured that it is directly below the hook.
3. The heavy object is inclined when it leaves the ground, indicating that the hook and the center of gravity are not connected to the vertical line passing through the center of gravity.
4. If the slope is greater than 5 degrees, reduce the slope and reconfigure.
5. Such as weight has a symmetrical shape and density stability, the center of the geometric center of gravity.
6. In the application of hoisting, symmetrical heavy objects such as I-beams, pipes and steel plates can be continuously lifted with the center of gravity.
7. Such as shape or irregular density distribution, from closer to the center of gravity of the heavier part.
The hoisting operation of the sling sling also requires maintenance:
1. To ensure information security, the activity clip should be fastened when wearing it, and it should not be used at high temperatures above 120°C. When using it, check the appearance first, and if it is found to be damaged, stop using it.
2. The use of the seat belt should be hung high at the bottom to prevent swinging and collision. It should be used without knots or directly hung on the safety rope. It should be hung on the connecting ring and used when the body is under load.
3. It should be cleaned frequently. After using it on the shelf, it should be washed with soap and water. In the warehouse with relative humidity of 80% or below, it should not be exposed to open flames, acids and chemicals. Do not collide with sharp objects and do not expose to the sun.
4. For hoisting operations with the buckle hoisting belt, the safety belt will be used for one year after purchasing a large number of samples. Around the static load test rod, the tensile force is 1 minute to 225 kg, the impact test of the seat belt is hung, the weight of 80 kg, does not destroy the free fall test, and the batch can continue to be used.
