When using lifting belt for lifting operation, why repeatedly emphasize that the hook should be perpendicular to the center of gravity of the heavy object, which is to ensure the safety of lifting operation. The main reason why vertical lifting is so important is that there are too many serious injuries caused by slanting lifting in recent years, and many people lack the most basic safety meaning and physical knowledge.
When using assembly with assembly to ensure that the lifting point and center of gravity as a vertical line, just can make the weight does not occur in the process of lifting, on the contrary, if both are not vertical, so the weight will make "the pendulum movement", and the deviation Angle, the greater the oscillation amplitude is, the greater the kinetic energy is, the greater the move at the same time around the equipment damage.
Therefore, in the use of lifting belt lifting operations must prevent the occurrence of pendulum movement, and the most effective method is vertical lifting, and other staff should enhance the awareness of safety protection, avoid walking under and around the weight, in order to prevent injuries or collisions and other accidents.
