ROTATION CONTROL DEVICE, ROTATION CONTROL METHOD, AND CONSTRUCTION MACHINE |
摘要 |
<p>In an electrically rotated shovel (construction machine)(1), when ground pressure in the direction opposite the direction instructed by a lever is applied to a rotating body (4), control system changing means (150) of a rotation control device (100) greatly changes a torque output of an electric motor (5) for driving the rotating body (4). As a result, the shovel can excellently cope with the applied ground pressure, and the rotating body can be prevented from continuously rotating in the opposite direction. As a consequence, even if ground pressure becomes high, there is no fear of the pressure affecting work, and in addition, even if the rotating boy is rotated on a slope, the rotation body is prevented from being greatly returned by the weight of a boom and an arm.</p> |
