1. It is strictly forbidden for people to stand under the billet clamp when lifting it.
2. When lifting, try to clamp the center of the billet for lifting. If it deviates from the center, it will increase or exceed the rated weight of the single-leg clamp and reduce the service life of the clamp.
3. If the clamp has small wear and tear, it should be repaired immediately, otherwise the damage of the spreader will be accelerated.
