Abstract
On a turn frame of an excavation machine, a hydraulic oil tank is placed in the center of a right engine chamber in the front-back direction, a control valve is placed in front of the hydraulic oil tank, a battery is further placed in front of the control valve, and a cool mechanism is placed behind the hydraulic oil tank. The control valve is supported by a support member, and a controller that outputs a signal for driving the control valve is mounted to a side plate part of the support member, thereby to be placed in a position in front of the control valve and above the battery.
Claims18
A construction machine comprising, in a housing chamber on a side of a machine body:
- a hydraulic oil tank configured to hold a hydraulic oil discharged by a hydraulic pump configured to be driven by a prime mover;
- a control valve configured to control a flow direction and flowrate of the hydraulic oil to a plurality of hydraulic actuators configured to be actuated by the hydraulic oil discharged from the hydraulic pump;
- and
- a controller configured to control the control valve, wherein:
- the control valve is positioned in front of the hydraulic oil tank, and
- the controller is placed entirely in front of the control valve.
A construction machine comprising a housing chamber on a first side of a machine body, the construction machine further comprising, in the housing chamber:
- a hydraulic oil tank configured to store a hydraulic oil;
- a control valve configured to control a flow of the hydraulic oil to a plurality of hydraulic actuators;
- a partition separating, in the housing chamber, a space including the hydraulic oil tank from a space including the control valve;
- and
- a controller configured to control the control valve, wherein:
- the control valve is positioned in between the hydraulic oil tank and the controller, and
- the control valve is supported by the partition.
A construction machine comprising a housing chamber on a first side of a machine body configured to rotate about an axis, the construction machine further comprising, in the housing chamber:
- a hydraulic oil tank configured to store a hydraulic oil;
- a control valve configured to control a flow of the hydraulic oil to a plurality of hydraulic actuators;
- a controller configured to control the control valve;
- and
- a battery configured to supply power to the controller, wherein:
- the control valve is positioned between the hydraulic oil tank and the controller, and
- the controller is positioned relative to the battery such that a line parallel to the axis extends through the controller and the battery.
