What is the formula of crane leg?

Lifting is no small matter, look at the high-voltage line first, and then ask about embedding. Legs are the most important, so avoid sewers and thin roads. In case of soft foundation, the stone should be padded first, and then the pad plate should be padded until it does not sink.

Test the oblique leg, calm down immediately, raise your arm to see if there are any high-voltage lines, and look around the four legs for defects. Look at the rear counterweight to see if it can turn smoothly. First, observe whether the lifting point is correct, whether the sling is defective, whether the lifting ring is damaged, and whether the personnel stand aside. Peace is another day.
