Does extending a telescoping boom without lowering the hoist create a risk of two-blocking?

Extending a telescoping boom without lowering the hoist can indeed create a risk of two-blocking. Two-blocking occurs when the hook block makes contact with the boom tip, which can lead to serious equipment damage, potential injuries, or even fatalities. When the boom is extended while the hoist is still raised, there is a higher chance that the hook block will come into contact with the boom itself, especially in cases where the load is heavy or if the boom is overextended.

This scenario emphasizes the importance of following safety protocols, which include ensuring that the hoist is lowered appropriately before extending the boom to prevent any accidents. Proper training and awareness of the mechanics of the crane and the boom system are crucial for operators to avoid situations that might lead to two-blocking, thereby ensuring safety and the integrity of the equipment.
