Typically there are three major groups of under running cranes. Patented track bridge cranes, enclosed track bridge cranes, and “I” beam or WF beam under running cranes lend themselves to an incredibly diverse range of applications, each with their own advantages.
Patented Track Bridge Cranes
The first group, patented track bridge cranes run on patented track, which is a fabricated section with a hardened running service. The track itself wears very well in tougher applications, and the track can be designed to yield tremendous wheel loads.
Patented track systems lend themselves to heavy capacity, heavy use or "switching" or "spur" track applications.
Enclosed Track Bridge Cranes
The second group, hugely popular today is the enclosed track style bridge cranes. The enclosed track is perfect for lighter capacities and usually manually operated cranes.
The enclosed track is ergonomically designed to roll very easily. The enclosed track type crane has become the push/pull crane of choice in most work cell applications.
“I” Beam or “WF” Beam Under Running Cranes
The third type of under running crane is the classic "I" beam or "WF" beam crane. Very economical to build, this style crane will run on an "I" beam or "WF" beam lower flange. This type of crane is good for larger capacity, lighter duty applications. If this type of crane is applied properly and built right, it will provide many years of good service with very little downtime.
When Not to use an “I” Beam or “WF” Beam Crane
Put this type of crane in the wrong application, and you can spend thousands of dollars on wheel problems and replacing bad sections of runway beams. At Capco, we will help you select the right type of crane for your application.
