Top Running Overhead cranes

 

Top running overhead cranes are one of the most commonly used industrial lifting devices today.

 

 

What is a top running crane?

A top running overhead crane is an industrial lifting system where the crane rests on rails installed at height, usually on beams attached to a dedicated supporting structure. The runway tracks are usually freestanding or integrated into the building structure.

 

 

Technical specifications

 

  • Lifting capacity: up to ~ 160 metric tons
  • Span: up to ~ 40 meters
  • Lifting height: variable
  • Hoist type: chain or wire rope
  • Runway tracks: Solid square rails or ASCE type mounted on runway beams

 

Possible configurations:

  1. Single beam or double beam
  2. Several connections possible, depending on building
  3. Other capacities, spans and lifting heights available on request

What are the advantages of
top running overhead cranes?

  • High lifting capacity and span.
  • Flexibility of configuration, single- or double-girder, with a variety of connections depending on the building, or with a maintenance bridge.
  • Combined with a freestanding structure, it's ideal for buildings that weren't designed to accommodate an overhead crane.

 

What are the disadvantages
of top running overhead cranes


  • The columns of a freestanding structure take up a lot of floor space.
  • No cantilever possible
  • Requires rails and a structure capable of supporting loads, unlike a forklift truck.

Frequently asked questions

01.
In the structural plan, one of the columns encroaches on an emergency exit door. Is this a problem?
A : Yes! No obstructions, fixed installations or turnstiles may encroach on the required width of an emergency exit (National Building Code NBC-2015, article 3.4.3.3).
02.
What distances do I need to respect around an electrical unit for my structural project?
A : A clearance of 1 m in front of an electrical panel is required to ensure safe access for maintenance, inspection and emergency response. (Canadian Electrical Code CEC, Article 2-308).
03.
How can I check if the concrete slab can bear a self-supporting overhead crane structure?
 A : Slab specifications are generally indicated in the quotation from your structural supplier. After validation by the engineer, they will be added to the design plans.

In general, it's up to the owner to check the slab. They can consult their building's construction plans or inspect the existing installation. Premium Industrial Group also offers an accompanying service, including scans or coring of the slab.

The aim is to ensure that the slab meets the engineer's requirements. Please note that this verification does not serve as a certification of capacity. We recommend that you document and archive these analyses.
