Abstract:
Provided is hybrid construction machine that can charge/discharge an electrical storage device appropriately and can suppress stop of an engine accompanying sharp increase of a load. The present invention includes a hybrid controller 22 that controls power of a hydraulic pump 17 and electric power of an inverter 15 in response to storage battery characteristics of the electrical storage device 16, and an output command unit 22F of the hybrid controller 22 is configured to control at least either one of the power of the hydraulic pump 17 and the electric power of the inverter 15 on the basis of at least either one of electric current or voltage of the storage battery characteristics and at least either one of temperature or a state of charge of the storage battery characteristics.
Abstract:
A system and method for capturing information related to mining machine performance and making the information accessible to remote maintenance staff. The information can be used to generate alarms, determine a state of the machine, determine performance statistics for the machine, and identify problems with the machine that may require attention. The information can be provided in a state message and the data can be packaged as XML data or in a string format. The data associated with a message can be particular to the current state or context of the mining machine. That is, in the case of a rope shovel, different data may be included in a message generated in a swing state versus a message generated in a tuck state. In some instances, a message is generated when progress thresholds are satisfied, such as for each foot of drilling performed by a mining drill.
Abstract:
A hydraulic system includes one or more sensors configured to measure a pressure at least one input or end of a hydraulic actuation device, such as a cylinder for example. A control module can be operatively coupled to the sensors and at least one metering valve. The control module can selectively open the metering valve when the pressure at one of the ends of the cylinder reaches a first pressure threshold to control the force on the cylinder rod, to permit flow from the end of the cylinder to the tank.

Abstract:
A working vehicle includes a vehicle, an engine, an exhaust treatment apparatus, a connecting pipe, a reducing agent injection apparatus, a reducing agent pump and a guiding pipe guiding reducing agent from the pump to the injection apparatus. The engine, exhaust treatment apparatus, connecting pipe, and reducing agent injection apparatus are arranged inside an engine room of the vehicle body. The engine has a crank shaft, and intake and exhaust manifolds arranged on first and second direction sides of the crank shaft, respectively. A first accommodating space is positioned on a first direction side of the engine room. A reducing agent pump is arranged inside the first accommodating space. A guiding pipe is arranged so as to pass inside the engine room on the first direction side with regard to the crank shaft.
Abstract:
An operator's seat mounting section (11) that is positioned in back side of a floor member (10) includes a seat plate (11D) for mounting an operator's seat (14) and an equipment mounting part (11F) that rises upward from the right side of the seat plate (11D), and a right operating lever assembly (16) is provided in front of the equipment mounting part (11F). A controller accommodating space (21) is provided to be positioned in back side of a console (16A) of the right operating lever assembly (16) and between a side surface (11F1) of the equipment mounting part (11F) of the operator's seat mounting section (11) and the operator's seat (14), and a controller (27) is mounted in the controller accommodating space (21) to control various kinds of electric equipment.
Abstract:
To provide a swing-type construction machine that can reduce force of working device pipes which is generated in accordance with swinging of a working device and presses against a side wall of a swing post. The present invention is configured such that a swing frame side holding body for holding a part of working device pipes 21, which is located at a side of a swing frame 2a, includes a first clamp 22 having a first stage holding portion that clamps one of the group of the working device pipes and a second stage holding portion that is arranged on a position lower than the first stage holding portion and clamps the other group of the working device pipes, while a swing post side holding body for holding a part of the working device pipes 21, which is located at a side of a swing post 6, includes a second clamp 24 having a first stage holding portion that clamps the group of the working device pipes that are clamped, by the first stage holding portion of the first clamp 22 and a second stage holding portion that clamps the group of the working device pipes that are clamped by the second stage holding portion of the first clamp 22.
Abstract:
A cab (8) is provided with a cab box (13) in which a space between each of pillars (14 to 18) is covered by each of surfaces (13A to 13F) and the inside becomes an operator's room (13G) and a door (24) mounted on the left intermediate pillar (16). On a rear surface portion (14D) of the left front pillar (14), a protruding portion (23A1) of a mounting plate (23A) is provided in a state protruding to the door (24) side. On a mounting opening (24E) on the inner surface side of the door (24), a door holding member (28) engaged with an engaging member (23) and holding the door (24) at a closed position is provided. On the door (24), a retreating recessed portion (29) for avoiding interference with the protruding portion (23A1) of the mounting plate (23A) is provided on the front side from the door holding member (28).
Abstract:
The hybrid excavator includes: a first detection sensor for detecting an RCV-manipulated quantity; a second detection sensor for detecting the rotational speed of an electric motor; a hydraulic pump-motor connected to the electric motor; a hydraulic cylinder connected to the hydraulic pump-motor; first and second hydraulic valves installed in first and second passages, respectively, between the hydraulic pump-motor and the hydraulic cylinder; a third hydraulic valve for compensating for or bypassing a flow rate and a controller for receiving an RCV-manipulation signal from the first detection sensor and the rotational speed of the electric motor from the second detection sensor to compare the received values to data of previously stored working conditions, to output a control signal for switching the first and second hydraulic valves, and to block a working fluid from returning into the hydraulic cylinder, so as to thereby quickly stop the working device.
