Long Span Cranes

Prefabricated metal buildings are increasingly moving towards widespan bays.  This requires overhead crane systems that have longer spans and heavier lifting capacities.  In addition, many considerations come in to play when designing and engineering long span crane systems in prefab buildings.  We have the knowledge and expertise to guide our clients towards the safest, most efficient solutions.

Here’s a glimpse in to one of our most recent jobs in a prefabricated metal building:


Special Considerations:

  • Overhead crane with span over 60 feet requires fabricated box girders
  • Long span cranes take up a large amount of the height in the building
  • Trucking and installation require special considerations and know-how


Our Team Approach:

  • Our team of engineers developed programs to design box girders for crane spans up to 110 feet
  • Our fabrication facility has the box girder weld tables and automated welding equipment to fabricate box girders to 110 feet
  • The Installation crew developed procedure and safety standards for handling long span box girder
  • Crane-Tec uses low head room trolley design to maximize building height

[Crane-Tec Runway Systems with spans up to 90 feet.]



Cranetec has mastered the ability to engineer, fabricate, and install long span cranes at a very cost effective price.  We also do complete startup and testing of the installation for maximum efficiency and safety.

Crane-Tec worked our magic again when a large international manufacturing company asked us to build and install a 15-ton top running double girder crane that will operate on an existing 10-ton capacity runway system.  Here’s what we came up with:

Special Considerations:

  • The existing runway system is designed for 10 ton.
  • The lifting height of the new 15-ton crane can be no less than the existing 10 ton crane.


Crane-Tec’s team collected information on the existing 10-ton crane and runway system and our engineer offered two solutions:

  • A 15-ton top running double girdle crane with a low headroom trolley hoist and a 15’-0” end truck wheelbase. The wheelbase was calculated to not overload the existing 10-ton runway system.
  • A 15-ton top running double girder crane with a low headroom trolley hoist. The trolley hoist has load limiters and travel limiters to restrict the 15-ton load to the center one-third of the crane span. The rail-side one-thirds are limited to 10 ton.

[Our engineers design to your specific needs.  That’s what sets us apart!]


The customer selected solution #1.

Crane-Tec furnished, installed, and tested the new 15-ton top running double girder crane with low headroom trolley hoist and a special 15’-0” wheel base on time.
