Front lifting equipment for crawler tractor, and crawler tractor equipped therewith

Front lift equipment for a crawler tractor, for agricultural use, having a substantial overhang of its front part relative to an intermediate transverse girder which constitutes the farthest forward bearing element of the tractor framework, to which there is fixed, on each side, a crawler set, adjustable transversely to adjust the track of the tractor, there being an axle at the rear of the tractor, a reinforcing member arranged on each side of the tractor and fixed to the intermediate girder and to the rear axle, and connecting means between the reinforcing member and a point of attachment of a part subjected to the forces generated by a load, a supporting structure (25) fixed to the front of the tractor with, on each side of the supporting structure, a lifting arm (26) projecting forward, this arm being articulated at its rear end (27) to the supporting structure which is fixed at the rear, on each side of the tractor, to a plate (29) fixed to the framework of the tractor,

• each reinforcing member having a flank (18d, 18g) of small thickness (e), roughly parallel to the vertical mid-plane of the tractor, located in the vicinity of the body of the tractor inside the crawler tracks (Cd, Cg), the height of the flank being designed to provide satisfactory mechanical strength, the thickness (e) of the flank (18d, 18g) being such that the setting of a narrow tractor crawler track is not impeded, said connecting means (L) extending between a front top end (19d, 19g) of said flank and a point of attachment (31d, 31g) located farther forward and lower down and secured to framework of the tractor.
