PARTICULAR CASES FOR THE CONSTRUCTIVE OPTIMIZATION OF THE LIFTING ARM FROM THE FRONTAL LOADER WORKING EQUIPMENT

Sorin-Dragos CRUDU

Abstract


This article presents and discusses particular cases for the constructive optimization for the lifting arm of the frontal loader equipment. As a general shape, this is considered as a double bent upside down Z, with forces and moments placed on it. All the mathematical expressions for the final value of the vertical and horizontal displacements of the bucket joints, get particularities as in the shown cases.
