摘要

FIELD: rolling equipment, namely transporting apparatuses, particularly roller table of rolling mill. ^ SUBSTANCE: roller table includes driven transporting rollers and lifting mechanism; lifting framework jointly mounted on struts and supporting transporting rollers; additional mechanism for lifting framework. Each mechanism for lifting framework is arranged in strut and it is in the form of sleeve, nut mounted inside said sleeve with possibility of motion and jointly connected through lug with framework; worm reduction gear joined with sleeve. In reduction gear and in sleeve there is opening in which screw is arranged. Said screw has cut splines in one end and in other end it has thread engaged with nut of sleeve. At least in one strut rotary crosspiece is jointly mounted. Lifting mechanism is mounted on said crosspiece. ^ EFFECT: enhanced operational efficiency of mill due to elimination of jamming movable links. ^ 2 dwg
