ANALYSIS OF THE DEVELOPMENT OF GRAVITY EXCAVATORS
ABSTRACT
This article analyzes the current state of operation of a hydraulic excavator in the
world and in our republic. The hydraulic schemes of the hydraulic excavator operation
are presented and the aspects of the advantages of steel rope excavators are analyzed.
A comparative analysis of the parameters of a steel rope excavator with a bucket of the
same volume and a hydraulic excavator is presented.
Keywords: hydraulic excavators,
steel rope excavators, hydraulic circuit,
hydraulic sleeves.
KIRISH
Hozirgi kunda dunyoning barch nuqtalarida qo’llanilayotgan gidravlik
ekskavatorlar. 1882-yilda birinchi bo’lib gidravlik texnologiyasi qo’llaniladigan
ekskavator ser U.G.Armstrong kompaniyasi Angliyada qurilgan bo’lib
Halla dokini
qurilishida ishlatilgan. Hozirgi zamonaviy gidravlik ekskavatordan farqli tomoni
qollanilayotgan ishchi suyuqligi suv bo’lgan. Faqatgina birinchi to’liq gidravlik
ekskavator 1897-yilda Kilgore Machine Companiya tomonidan arqonli uzatmalarsiz 4
ta parli silindrlar bilan to’g’ri ta’sir etadigan qurilgan. [1] (1-rasm)
