摘要:
A lifting and tie-down arrangement is provided for a push frame and scraper bowl assembly and includes a first bracket removably affixed to the outside and/or inside of the draft arm socket in the side walls of the scraper bowl. A second bracket is selectively affixed to the side legs of the push frame whereby lifting equipment connected to the first bracket on the outside of the bowl and to one second bracket on the push frame can be used to safely lift the assembly. Tie-down cables connected to one first bracket on the inside of the bowl and to the other second bracket on the push frame can be used to safely tie the assembly to a flatcar or the like.
