FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to support devices of platform body installed on jacks. Proposed support device contains shoe with cylinder installed in center and with stiffening ribs. Cylinder is made hollow and step for jack is installed on upper ed face of cylinder. Said step is provided with projection with fitted-on elastic member made in form of rubber hose with plug secured in lower part, with minimum two threaded holes from end face side for fastening support plate. Area of support plate exceeds area of shoe sole. Shoe rests on support plate with displacement at leveling of platform body in horizontal direction at angle of tilting of surface to horizontal greater than 0. ^ EFFECT: no influence of unpredicted resistance of ground to jack owing to normalized coefficient of friction. ^ 2 dwg |
