ABSTRACT:
An improved gantry crane that has a control cab mounted for vertical up and down movement substantially parallel with respect to the upstanding columns of the crane between a lowermost position adjacent the ground and infinite positions within a fixed range. One or both of the sill beams of the crane include a downwardly offset mid-portion extending adjacent to the ground but spaced therefrom with the mid-portion of one of the sill beams being positioned to receive the control cab when in the lowermost position thereof. A supporting beam supports the control cab therebeneath so that the operator in the cab has a 360 degree substantially unobstructed view in all directions.
