Tie Back Links (Crane Girder Surge Connectors)

Molyneux Industries manufactures two types of tie back linkages (crane girder surge connectors) which are used to allow crane girder end rotation on overhead crane runways.  These bearing tie back linkages prevent the kind of fatigue failures that are common with traditional fixed tie back (diaphragm) connections.  The Molyneux PFSL type tie back linkage has internal bearing seals.  The TBL type tie back linkage is installed with external o-ring seals.  Examples of both types of linkages are shown below.  Both the TBL and PFSL type tie back links are available in a large variety of sizes and can be custom designed and manufactured by Molyneux to fit almost any project requirement.

 Assembly Example

PFSL Bearing Tie Back Link (Surge Connector)

(Internal Seals)

This tie back link is faster and easier to install on site and provides some dimensional flexibility over the TBL/Series.  The PFSL type tie back link is available to ship as an assembly or as the link only. 

TBL Bearing Tie Back Link (Surge Connector)

(External Seals)

This tie back link offers a slightly cheaper design solution in many instances.  This link series allows a wide variety of connection solutions.  The TBL type tie back link is generally shipped to site pre-assembled.

Tie back links (surge connectors) are generally custom made to suit each project.  We can manufacture more sizes than those displayed on our tabulated list of available tie back links.
