The hook of a bridge crane is a key component for lifting materials. There are various types of hooks suitable for different lifting needs. Correctly selecting the type of hook is essential to ensure lifting safety and improve work efficiency. 1. Single hook The single hook is the most common type of hook and is suitable for most conventional lifting operations. It has a simple structure and is easy to operate, and can meet the lifting needs of general materials. Single hooks are usually used for cranes with smaller lifting weights and are widely used in factories, warehouses and other places. 2. Double hook The design of the double hook allows for the simultaneous lifting of two different materials or for more complex operations in one lift.
