Abstract

1,263,024. Steering articulated vehicles. EISENWERK GEB. FRISCH K.G. AUGSBURG. 5 May, 1970 [7 Aug., 1969], No. 21561/70. Heading B7H. [Also in Division E1] A grader comprises a frame 5 articulated to a rear wheeled chassis 2 and to front wheels 9, hydraulic rams 7, 8 and 10, 11 mounted for moving the frame relative to the chassis 2 and the wheels 9, respectively, and a valve 13 in the hydraulic circuit for the rams which in one position hydraulically interconnects the rams so that when either pair of the rams is operated the fluid displaced therefrom operates the other pair to steer the grader in the same direction, and which in a second position permits operation of the rams 10, 11 only.
