Abstract
Abstract The invention relates to a procedure in car body rectifying work. In the procedure the vehicle is driven onto the rectifying table (11) of the car body rectifying unit (10) and affixed to skirt attachments (12) provided on the rectifying table. The vehicle is raised, while it is on the rectifying table, with the lifting unit (16) of the vehicle rectifying unit to desired height for the rectifying work. Hereafter the lifting unit (16) is removed from under the vehicle and out of functional connection with the rectifying table (11) and the vehicle is left resting on supporting legs (30) connected with the rectifying table (11). The invention also relates to apparatus conforming to the procedure.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
148 words
Apparatus for supporting an object so that it can be rectified, comprising a plurality of separate rectifying tables, a single lifting arrangement which is engagable with each said rectifying table, and is movable underneath each said table and out from under each said table, each said rectifying table additionally comprising supporting legs which are movable to a position supporting said table when said lifting arrangement has been moved out from thereunder, cantilever beams forming part of each said rectifying table, and disposed to be couplable to said supporting legs, at least three driving plates arranged to allow said cantilever beams to be situated in gaps therebetween in a lowest position of said rectifying table, said driving plates being coupled to said lifting arrangement to be removable when said rectifying table has been lifted to an appropriate repair height, so that said driving plates do not disturb repair work.
Claim 2
Dependent Claim
