What is a girder in a crane?
A girder is the main support beam in a crane A girder in a crane refers to the primary structural beam that carries loads and supports movement. It forms the backbone of overhead lifting systems. This beam bears the weight of hoists, trolleys, and the lifted object as it travels along the runway. Key roles of the main beam A girder: Supports hoist and trolley movement Transfers loads to end trucks Maintains balance across span In industrial overhead cranes, the design of the girder directly affects load capacity, travel smoothness, and reliability. YG Crane builds single and double girder systems for various heavy lifting needs. Girder design determines crane strength The shape and structure of a girder define how much load it can carry. A strong beam resists bending and deformation. In heavy duty systems, engineers use robust steel sections or box structures to increase strength. Structural aspects that matter Girder strength depends on: Beam cross‑section Material grade Fabricat...
