FIELD: construction. ^ SUBSTANCE: excavator comprises carrier with travel mechanism and rotary platform, where the following components are installed - cabin, working equipment, which comprises boom, handle, bucket, double-leg stand, on which boom is fixed by means of anchor ropes, body with lift and rotation mechanisms, discharge mechanism. Rotary platform consists of two parallel boxy beams, which are produced by pair vertical metal sheets and upper and lower metal belts. Central part of platform is arranged between beams, and its height is equal to height of vertical metal sheets. Metal sheet is installed at front ends of boxy beams and central part of platform, and vertical ribs are rigidly fixed on it symmetrically to external vertical sheets of boxy beams. Excavator is arranged with the possibility of unification due to application of rope and rack discharge mechanism. Axis of rack discharge mechanism boom is placed in holes provided into vertical ribs, and distance between brackets of anchor ropes fixation on double-leg stand is equal to distance between anchor ropes at upper part of boom. ^ EFFECT: excavator unification, namely, such arrangement of rotary platform that makes it possible to install working equipment with rope or rack discharge mechanism on a single base, depending on developed object, with preservation of machine parametres. ^ 6 dwg |
