Tieback assemblies

Tiebacks / Surge connectors for connection between a girder and a building column

What's a tieback?

A tieback is the connection between a girder and a building column that facilitates the transfer of forces.

When a crane travels down a runway, it generates vertical, longitudinal and lateral forces. The lateral forces go from the crane wheel into the web of the rail, are transferred to the crane rail clips through
the rail flange and from there into the crane girder. These forces have to be transferred from the crane girder to a building column, located at the end of the girder, and into the foundation.

Single tieback

If there is limited space, between the column and the girder, single tiebacks are mounted to the sides of the column. Single tiebacks are also used for runway end girders or where a continuous girder bridges a building column.

double tieback

Double tieback

The normal tieback, placed at a location between two adjacent girders, consists of one bracket each for the two girders, connected with two links to a common bracket on the column. This is considered a double tieback.
