    摘要: A construction machine includes: a work device; an operation device which receives a manipulation; a hydraulic unit including a hydraulic motor; an electric unit including an electric motor and an energy storage unit; a control device which makes the electric power of the energy storage unit assist the hydraulic unit upon the manipulation for the drive side, and makes the electric motor generate regenerative electric power unit upon the manipulation for the regeneration side; and a power-discharge command unit which issues a discharge command for the energy storage unit. Upon receiving the discharge command, the control device operates the electric motor to lower a voltage of the energy storage unit upon the manipulation for the drive side, and makes only the hydraulic unit decelerate or stop the work device upon the manipulation for the regeneration side.

    摘要: A slewing stop control apparatus and method, capable of executing, while performing the control of determining the target slewing velocity based on a remaining slewing angle from the actual slewing motion position up to the slewing stop angular position, an automatic control of re-slewing the slewing structure having been stopped before the slewing stop angular position. The apparatus executes slewing angular velocity control for deciding the slewing braking start timing to stop the stewing structure at a slewing stop angular position in accordance with a predetermined slewing deceleration and the subsequent target slewing angular velocity, based on the remaining slewing angle of the slewing structure. When the slewing structure stops before the slewing stop angular position due to disturbance despite the foregoing control, the target slewing angular velocity is corrected to be increased for generating slewing torque to restart the slewing.

    摘要: A swing system for construction machinery or a vehicle, particularly an excavator or a crane, includes a swing brake for blocking or unblocking a rotational movement of a first portion of the vehicle relative to a chassis portion of the vehicle, and a swing pump and a swing motor are provided for performing the rotational movement. The swing pump can be positioned in a neutral position where no rotational movement of the first portion takes place. At least one brake control actuator is provided for automatically engaging the brake when the swing pump is in its neutral position. The swing system can provide an improved control of the swing movement on a slope and an improved comfort during operation of the swing movement.

    摘要: A machine (A) includes a frame (16) and a platform (58) on which a boom assembly (B) is mounted. Two arms (332) of a U-shaped pivotal member (330) are pivotably mounted to the frame (16) about a first pivot axis (380) perpendicular to a longitudinal direction of the frame (16). A front end (302) of a mounting plate (310) is pivotably connected to an intermediate section (336) of the pivotal member (330) about a second pivot axis (382) perpendicular to and spaced from the first pivot axis (380). Two rams (400) are mounted on opposite sides of a rear end (304) of the mounting plate (310). Each ram (400) includes a lower end (404) pivotably connected to the frame (16) and an upper end (402) pivotably connected to one of the sides of the mounting plate (310). The boom assembly (B), the mounting plate (310), and the pivotal member (330) pivot about the first pivot axis (380) and/or the second pivot axis (382) relative to the frame (16) due to relative movement of the rams (400).
