Large containers for moving cargo are frequently made of steel in which the side panels are strengthened by making them so as to have elongated alternate lands and grooves. The invention is an apparatus for reforming deformed lands and grooves and removing dents in the panels. It includes a power actuated tool for applying force against the deformed structure and a hydraulic power source connected to the tool. A four-way valve is used to supply pressurized fluid from the source to the tool. A frame connected to the hydraulic power source extends externally of the tool, of a tool holding stand, and of the deformed structure. On each side of the panels the frame has vertical members having protrusions which are adapted to move into spaced grooves formed on the outside of the panels and adjacent the deformation on one side of the container. On the other side of the container the protrusions fit in spaced grooves which have inner surfaces forming internal lands within the container on which a backing plate of the tool exerts a force when the tool acts to straighten a deformed groove or other surface.
