A EXCAVATOR HAVING REMOTE-CONTROLLER

摘要

PURPOSE: An automatic excavator for the extreme situation is provided to enhance working efficiency by the excellent switching performance between an excavation work and a boring work since without separating a bucket from an arm, a drill is installed on a drill position and a boring work is performed. CONSTITUTION: An automatic excavator for the extreme situation comprises a lower body(10), an upper body(20), a boom(30), an arm(40), a bucket(50) and a controller(80). The lower body comprises an endless track(11) to run to both sides and a hilling unit(13). The upper body is installed on the upper part of the lower body and rotates around a central vertical axis(Y). The end of the boom is hinge-connected to one side of the upper body and operates as a first hydraulic cylinder(31). The arm is hinge-connected to the end of the boom and operates as a second hydraulic cylinder(41). The bucket is installed on the end of the arm and operates as a third hydraulic cylinder(51), which is installed outside the arm. The controller is connected to the control unit(23) of the upper body wirelessly or by wire.
