  • Publication number: 20240010273
    Abstract: A bulldozer causes left and right steering clutches to engage and left and right steering brakes to release when an operating amount of a steering lever is greater than a first predetermined amount and less than a second predetermined amount, and drives a turning motor so that the rotation speed of an inside output shaft becomes lower than the rotation speed of an outside output shaft as the operating amount of the steering lever increases. A controller causes the engagement rate of an inside steering clutch to decrease and causes an inside steering brake to brake when the operating amount of the steering lever is equal to or greater than the second predetermined amount.

  • Publication number: 20240001989
    Abstract: A controller of a crawler type work machine controls left and right steering clutches, left and right steering brakes, and a turning motor to cause the crawler type work machine to turn in either a slow turning mode or a pivot turning mode. The controller executes a hydraulic fluid amount control to reduce a hydraulic fluid amount supplied from a hydraulic pressure supply unit to the turning motor and to increase the hydraulic fluid amount supplied from the hydraulic pressure supply unit from the hydraulic pressure supply unit to the work implement cylinder when the work implement cylinder is driven while the turning motor is being rotated.

  • Publication number: 20240001988
    Abstract: A controller provided in a bulldozer maintains the engagement of an inside steering clutch over a predetermined period beginning from a switching start point at which switching starts, when switching from a slow turn mode to a pivot turn mode, and when switching from the pivot turn mode to the slow turn mode, maintains the braking of an inside steering brake over a predetermined period beginning from a switching start point at which the switching starts.

  • Patent number: 11549238
    Abstract: A system includes a processor and a display. The processor acquires shape data indicative of a shape of the surroundings in a traveling direction of a work machine. The processor generates a guide line. The guide line is disposed spaced from the work machine. The guide line indicates the shape of the surroundings in the traveling direction of the work machine. The processor synthesizes a surrounding image and the guide line and generates an image including the surroundings image and the guide line. The display displays the image including the surroundings image and the guide line based on a signal from the processor. The system may further include the work machine, a camera that captures the surrounding image, and a sensor that measures the shape of surroundings.

  • Publication number: 20210395982
    Abstract: A system includes a processor and a display. A LiDAR is attached to a work machine and includes a laser and a photodetector. The LiDAR measures a distance to at least a part of a work implement and a distance to an object around the work machine. The processor acquires position data from the distances measured by the LiDAR. The position data indicates a position of at least the part of the work implement and a position of the object around the work machine. The processor generates an image indicative of the position of at least the part of the work implement and the object around the work machine based on the position data. The display displays an image in response to a signal from the processor. The system may further include the work machine and the LiDAR.

  • Patent number: 7143852
    Abstract: An engine compartment cover for a work machine includes left and right-hand side covers for covering the sides of an engine, and a hood for covering the top of the engine. The engine compartment cover serves to enclose the engine and demarcate an engine compartment and is capable of suppressing the noise at the operator's ear level caused by the engine operating noise passing through the engine compartment cover as far as possible, whereby the level of quietness in the operator cab can be improved.
