The connection between runway girder ends and building columns is a common area of failure on overhead crane runways. Often called tieback connection or surge connector, this joining proves subject to the fatigue stemming from flexural stresses in runway girders from crane operations.
Eliminate common cracks & breaks between girders & building columns
GANTREX’ Crane Girder Tieback Assembly is the proven solution to accommodate flexural movements without fatigue, whilst providing the necessary load transfer to the building column. Our tieback assemblies are designed to fit on your crane loading and building configuration and can be used for new construction or runway refurbishment.
In-house design calculations
Our team of 300 genuine GANTREX crane rail specialists worldwide will guide and offer the tieback assemblies best fitting your needs with the support of our Technical Department’s design calculations, including crane loading, duty cycles, structural conditions and ease of installation.
