What is a reason you cannot attach slings to the teeth of an excavator bucket?

Attaching slings to the teeth of an excavator bucket poses a significant risk because the teeth are not designed to bear the forces involved in lifting heavy loads. They are typically made from materials that can wear and break under stress, and attaching a sling directly could lead to a situation where a tooth fractures or breaks off entirely. This would result in the load being dropped unexpectedly, creating considerable safety hazards for anyone nearby and potentially damaging equipment.

While balancing the load is important and the strength of the teeth is a factor, the primary concern is the integrity of the teeth themselves. Proper lifting techniques involve securing the load in a manner that ensures all components can safely handle the weight and operational stress. Therefore, relying on the teeth for attachment doesn't meet safety standards and increases the risk of accidents.
