FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to machinery field, provided for implementation of digging and loading operations, particularly to machinery of type of frontal bucket loader. Load-carrying system is formed by front half-frame, hinged to back half-frame, consisting two longerons with bearing of beam, counterbalance, accumulator boxes. On back ends of longerons it is rigidly fixed transverse beam with guidlines, on which there are mounted counterbalance and back lamellar element, fixation of which to transverse beam is implemented by means of releasable connection. Counterbalance is implemented as changeable and composite with ""-shaped openings and mass, providing stability of motion and manageability of loader with cargo, and accumulator boxes are implemented as demountable and fixed to back lamellar element and longerons. Accumulator boxes allow openings for installation of clearance lamps and backup lamps. ^ EFFECT: invention provides for stability increasing of frontal bucket loader at changing of vehicle capacity of frontal bucket loader ensured by variation of counterbalance mass, and also simplification of erection and dismantling, increasing of maintainability and serviceability. ^ 5 dwg |
