When a new or existing building has enough reserve capacity to resist the longitudinal (along the length of the crane runway) and lateral (across the width of the runway) forces, CraneWerks can attach the columns and runways to these buildings, reducing the amount of steel required to produce an overhead crane system. These systems are good where the requirement is for minimum floor obstructions and where maximum headroom (hook height) is required. Engineering services are available through CraneWerks to help you determine if your building has the required strength to utilize a money saving semi-freestanding crane runway system.

A main component of a semi-freestanding overhead traveling crane system is a top running single or double girder bridge crane designed with the bridge on the top of the runway. The crane runway is positioned on self-supporting columns.
