Abstract
Apparatus for removing forms from the girders of a bridge, including a frame structure, a carriage which is movable below the bridge girders, and a carriage support which is attached to the frame structure and which supports the carriage. The carriage is movable between two pivotal support arms which are pivotal between a stowed position and an operative position. The carriage is supported out from under the bridge when the support arms are in the stowed position. The entire apparatus may be easily manipulated to avoid contact with any portion of the bridge, in particular, the vertical pilings, as the apparatus moves along the length of the bridge.
