MACHINE FOR ERECTION OF PILES FOUNDATIONS FOR CONTACT LINE SUPPORT

摘要

FIELD: transport construction. SUBSTANCE: machine has hydraulic cylinder of mechanism of frame extension which is secured by body and rod to extension and turning frames, and drum is located between sprockets mounted on its end faces coaxially to it. Drum is made with grooves of different depth to receive electric cables and hydraulic hoses of different diameters whose centers in cross-section are located on common straight line parallel to generator of drum to ensure motion of power carriers of different diameters for the same distance with extension of frame and reliable operation of machine due to its simple design and convenience in mounting and operation. EFFECT: higher efficiency. 7 dwg
