Abstract (en)
[origin: EP0344390A1] The trolley comprises a frame (10) having two end axles (10A, 10B) between which is a Bissel bogie (10C, 16) whose chassis (16) is articulated to one of these end axles (10A), together with a guide bar (18) articulated between the axle (10C) of the Bissel bogie and the other end axle (10B). At least one wheel (C) of the Bissel bogie functions as a rail sensor. Grinding heads (T1, T2; T5, T6) are articulated via connecting rods (S1, S2; S5, S6) to this chassis (16) and to this guide bar (18) and are thus guided independently of the positions of the end axles, in a manner such that the point of contact of each grinder (M1, M2; M5, M6) follows the rails independently of the curves, thus compensating for the flexions at these points. <??>The trolley may have a plurality of successive Bissel bogies articulated to each other, each guiding grinding heads, or a system of levers for the indirect guidance of the grinding heads, this system being controlled by a measuring Bissel bogie. To compensate for the variation in the rails, telescopic Bissel bogies may be provided. <IMAGE>
