Overhead Crane

A lifting system mounted on runway beams above the floor — moving heavy materials or equipment both horizontally and vertically within a manufacturing or industrial facility.

Home Glossary Building Specifications and Features Overhead Crane
Definition

An overhead crane is a lifting system mounted on runway beams above a building's floor, used to move heavy materials or equipment both horizontally and vertically within a manufacturing or industrial facility. Installing an overhead crane requires a crane-ready building with structural columns and runway supports rated for the specific crane's capacity and span.

Key overhead crane specifications

SpecificationWhat it determines
Capacity (tons)Maximum weight the crane can safely lift
SpanWidth of coverage between runway rails
Runway lengthDistance the crane can travel along the building
Hook heightVertical lifting range available below the crane

What to watch for before committing

Capacity match to your operations

Confirm the crane's rated capacity meets your actual heaviest lift requirements, with reasonable safety margin.

Span and coverage area

Verify the crane's span and runway length actually cover the areas of the building where lifting is needed.

Structural compatibility

Confirm the building's structural rating matches the specific crane system's loads, whether existing or planned.

Maintenance and inspection history

Request maintenance and certification records for any existing crane system before relying on it.

Operator training and certification

Understand any operator certification requirements that apply to your specific crane system and jurisdiction.

Net clear height impact

Account for the crane system's own space requirements when calculating usable clear height below it.

When you need to know this

  • Heavy manufacturing and fabrication — moving heavy materials or components through production processes efficiently
  • Equipment-intensive operations — handling loads too heavy or awkward for standard forklift operation
  • Evaluating a building with existing crane infrastructure — assessing whether an installed crane system fits your operational needs
  • Planning new crane installation — confirming a building's structural readiness before committing to crane investment

Frequently asked questions

What is an overhead crane? +
An overhead crane is a lifting system mounted on runway beams above a building's floor, used to move heavy materials or equipment both horizontally and vertically within a facility.
Can any warehouse support an overhead crane? +
No — installing an overhead crane requires crane-ready construction with structural columns and runway beam supports specifically rated for the crane's capacity and span, which standard warehouse construction doesn't automatically provide.
What is crane capacity measured in? +
Crane capacity is typically measured in tons, indicating the maximum weight the crane system can safely lift, and should always exceed your actual heaviest lift requirement with a reasonable safety margin.
Does an overhead crane reduce usable clear height? +
Yes, the crane system and its runway beams occupy vertical space, so the usable clear height below the crane for other purposes is less than the building's total clear height.
