FIELD: mechanical engineering; lifting equipment. ^ SUBSTANCE: invention can be used for lifting welders, carrying out surface welding of bottoms delivered by manipulator in manufacture of high-pressure chemical apparatuses, and welding equipment. Proposed device contains cabin with fastened nut connected with vertical load screw. Screw is connected by upper end through gear coupling with output end of shaft of electric drive conical reduction gear, and by lower end, made in form of ball support, is installed in housing. device is furnished with support of welded structure with upper platform welded to support and furnished with railings on which electric motor is mounted together with reduction gear. Cabin is welded structure. Housing is made split being secured by foundation bolts and nuts. Bottom is fed and turned by means of manipulator, capacity 60 tons, to carry out surface welding of bottom with noncorrodible metal from platform of cabin. ^ EFFECT: provision of lifting of welders and welding equipment to preset height. ^ 2 dwg |
