AI Technical Summary

Problems solved by technology

The operating machine vibrates under the influence of this inertial force, which degrades ride comfort and work efficiency, and also negatively affects durability
In addition, since the stability of the work machine is degraded by the inertial force, there is a possibility of falling over when excessive deceleration is performed in a forced work posture.

Abstract

The purpose of the present invention is to provide a work machine capable of achieving stop characteristics appropriate for each drive actuator, using a simple structure and calculations, even when commands to the drive actuator are changed from an operation command state to a stop command state. The work machine (1) has a traveling member (2), a work machine body (3) mounted on the traveling member, a working front end (6) mounted on the work machine body in a vertically pivotable manner, and a control device (60) for controlling these. The control device (60) changes operations for each drive actuator so that stop characteristics, set for each drive actuator, are fulfilled when commands to drive actuators (7, 11, 13, 15) are changed from an operation command state to a stop command state.

Description

technical field [0001] The present invention relates to a work machine used in structure demolition work, waste demolition work, road work, construction work, civil engineering, etc., and particularly relates to a work machine having a stop characteristic suitable for each drive actuator. Background technique [0002] Conventionally, as working machines used in structure demolition work, waste removal work, road work, construction work, civil engineering, etc., there are known machines that are rotatably attached to the upper part of a running body that is driven by a power system. The main body of the working machine is equipped with a multi-joint type working front body so as to be able to swing freely in the vertical direction, and each front part constituting the working front body is driven by an actuator. As an example of the above-mentioned work machine, there is a work machine that uses a hydraulic excavator as a base, has a boom that is swingably connected at one en...
