Which type of equipment is primarily affected by shock loading during lifting operations?

Shock loading refers to the sudden application of a load that exceeds the normal operating load, which can cause significant stress on lifting equipment. Cranes are particularly susceptible to shock loading because they often lift heavy loads dynamically. For instance, when a heavy object is suddenly lifted, lowered, or dropped, the force exerted on the crane can be several times greater than the actual weight of the load.

This can cause not only physical damage to the crane's structure but also compromise the integrity of the load being lifted, leading to potential accidents or failures. In contrast, while forklifts, scaffoldings, and hoists can also experience loads, they are generally designed to handle different types of stresses and movements that are less variable than those encountered by cranes in lifting operations. Therefore, cranes are primarily affected by shock loading due to their operational characteristics and the types of loads they frequently handle.
