Abstract: A deployable gage restraint measurement system includes a measurement axle assembly, a cross member, first and second support frames, first and second load cylinders, first and second swing arms, and an anti-rotation arm. The first and the second support frames are each pivotally coupled to the cross member. The first load cylinder is pivotally coupled to the first support frame and the second load cylinder is pivotally coupled to the second support frame. The first swing arm is pivotally coupled to (i) the first load cylinder about a first axis of the first swing arm, (ii) the first support frame about a second axis of the first swing arm, and (iii) the measurement axle assembly about a third axis of the first swing arm. The anti-rotational arm is pivotally coupled to (i) the first support frame and (ii) the measurement axle assembly.

Abstract: A plow having symmetrical mold-boards and bodies, the plow comprising a hitch 1 connected in particular by means of a pivot 3 and to a main frame 4 which is provided with a pivot 18 receiving a hydraulic actuator 17 whose action causes a beam 8 to pivot about its axis 7 together with body carrier elements 10 provided with mold-boards 11, characterized by a symmetrical moldboard 11 having a concave working surface which is horizontally hollow 46 and vertically hollow 47, with each of its side ends taken in a front position tapering upwardly rearwardly, by a single deflector 45 for both working directions in the form of a sector of a melon, by a strut 10 comprising a safety system including two elements 36 and 78 capable of moving longitudinally relative to each other, and by a pivoting rear rudder blade.
