Single Leg Gantry (Semi-Gantry) – With the installation of an upper runway and a flush mounted floor rail, a single leg gantry can be utilized as a Top Running or Underhung crane. Single leg Gantries have greater lifting capacity than a Jib crane because the bridge is supported at both ends, and the load on the supporting structure is primarily vertical. This allows the supporting structures to be lighter than those needed for a Jib crane of equal load carrying capacity.
