FIELD: building, particularly equipment for performing earthwork with the use of hydro mechanization machines. ^ SUBSTANCE: hydro mechanization machine comprises tractor with cabin, bulldozer blade and hydraulic cylinders, rotary means with hydraulic drive, pump, hydrodistributor, pipelines and crane boom. Crane boom includes upper and lower parts pivotally connected one to another and having hydraulic cylinders. Lower part is pivotally connected to rotary means. Attached to upper part top is hook. Upper part of crane boon has lever and additional hydraulic cylinder. Lever may rotate in vertical plane. Lever is connected with additional hydraulic cylinder. Machine is provided with welding generator and hydroficated tools, particularly with angular polishing machine, and with at least two external supports, namely outriggers. Each external support is equipped with hydraulic cylinder having independent hydraulic control means. Welding generator and hydroficated tools have independent hydraulic motors, which are hydraulically connected to pump through common hydrodistributor unit. Rotary means is arranged on plate located behind tractor cabin. Machine has additional hook replaceable for excavator bucket. ^ EFFECT: increased operational reliability and safety. ^ 5 cl, 3 dwg |
