agricultural engineering. SUBSTANCE: ramp has carcass with supporting columns and handrail. Floor is attached to one side of carcass and face shield is attached to other side of carcass. Handrail is connected to upper ends of parallel supporting columns. Lower ends of supporting columns are pivotally connected to carcass which is attached to combine housing upper part for rotation and fixing in transport or operating position. Supporting columns are composed of two parts. Lower parts of columns are positioned for rotation relative to carcass through 90 deg. Upper parts of columns are positioned for rotation relative to lower parts of columns through 180 deg. Both parts of columns may be fixed relative to carcass within the face shield of ramp. Ramp of such construction allows upper part of combine to be serviced without the necessity of dismantling during transportation. EFFECT: simplified construction and increased efficiency. 2 cl, 6 dwg |
