Abstract: 605,581. Vehicle lifts. TECALEMIT, Ltd., and LE CLAIR, C. C. S. Nov. 1, 1945, No. 29069. [Class 78 (iii)] A garage vehicle lift of the run-on type, having wheel tracks normally flush with the floor, comprises a central casting 10 secured to the ram head 11 and carrying the wheel tracks at either end. Each track is a fabricated beam comprising a top flange plate 1 forming the track proper and a lower flange 6, 7 connected to it by longitudinal webs, whilst opposite the casting 10 there are longitudinally-spaced transverse webs to form a cross-beam extension of the casting. This avoids the necessity for transverse under supports to the tracks, and reduces the depth of the lift and of the ground pit required for it. In the construction shown, the longitudinal webs are formed by the inclined'sides of three channel members 3 whose upper edges are welded to the top plate 1, and plates 6, 7 are welded to the bases of the channels to form the lower flange. The track is secured against an inclined seating 12 of the central casting 10 by a series of bolts 14 extending right through it and down against a horizontal flange 13 of the casting by bolts 22. Arranged between the bolts 14 and extending in rows transversely of the track are packing pieces as 24, 25 filling the spaces between the sides of the channels 3. These packing pieces form the above-mentioned transverse webs, and several forms and arrangements of them are described. They may be short lengths of channel cut, for example, from the same stock as the main webs 3. Alternatively, trapezoidal plate members or triangular gussets may be employed. Short screws threaded into fillets located behind the inner side wall of the track may be employed in place of the screws 14 extending right across the track. The top flange plate may be folded down to form the sides of the track and the channel webs adjacent the sides completed by welded lengths of angle section.
