Glossary of Crane Design Terminology

A clear understanding of the terminology used in crane design can help you navigate the entire process with confidence. Here are some common terms you may encounter:

Capacity: The maximum weight the crane can lift, usually specified in tons.
Span: The horizontal distance between the rails or beams that the crane travels on.
Headroom: The vertical distance from the crane's hook to the overhead structure, such as the ceiling or building beams.
Lift Height: The maximum height the crane's hook can reach above the ground or work surface.
Runway System: The tracks or beams on which the crane travels within a facility.
Trolley: The mechanism that moves the hook along the bridge girder.
Girder: A major beam of the crane that supports the trolley and hook.
Clearance: The necessary space between the crane's components (such as the hook and the building structure) to allow for safe operation.
Fabrication Drawings: Detailed drawings that break down the crane into individual components, including specific materials and assembly instructions.
Preliminary Drawings: Early-stage design sketches that show the basic layout, dimensions, and key features.
Construction Drawings: Finalized drawings that specify exact dimensions, materials, and assembly details for the crane.
