摘要： A managing method of a mining machine includes: detecting a position of a landmark; and extending a first distance when a position of the landmark obtained in advance is present within a range of a second distance in a travel direction of the mining machine from a position, as a reference, where the mining machine reaches when the mining machine travels the first distance after the mining machine starts traveling by the dead reckoning navigation, when the mining machine travels in an unmanned state in a mine in which a plurality of the landmarks is located, the mining machine travels based on a detected self position and uses the dead reckoning navigation while correcting a current position of the mining machine based on a position of the landmark obtained in advance and a detected position of the landmark when the self position cannot be detected.

摘要： An operation lever of a work vehicle has the operation surface including: a connection portion; a front operation surface extending obliquely so that a height from a reference plane increases from the connection portion toward the forward side of the connection portion in a cross-sectional view including a front-rear directions and a front-side edge of the operation surface being defined as a front-side top portion; and a rear operation surface connected to the front operation surface, extending obliquely so that a height from the reference plane increases from the connection portion toward the backward side of the connection portion and a rear-side edge of the operation surface being defined as a rear-side top portion. A length in front-rear directions along the reference plane in the front operation surface is larger than a length in the front-rear directions along the reference plane in the rear operation surface.

摘要： A work machine management system includes: a position detector detecting a position of a work machine traveling on a travel route; a non-contact sensor detecting an object in a vicinity of the travel route in a non-contact manner; map data to accumulate information on existence and a position of the object in the travel route based on detection data obtained by the position detector and detection data obtained by the non-contact sensor; a travel route generator generating the travel route where the work machine travels; and an identifying unit to identify an area or a travel route having low perfection of map data of a travel route where the work machine travels. The travel route generator generates a travel route so as to cause the work machine not to pass the area or the travel route having the low perfection of the map data.

摘要： A control device includes a bucket control unit and a speed restricting unit. The bucket control unit calculates a control speed controlling a bucket so as to maintain an angle of the work equipment at a constant angle. The speed restricting unit reduces the control speed when the bucket is driven at the control speed calculated by the bucket control unit and when a direction in which the bucket is driven and a direction in which the arm is driven coincide with each other.

摘要： A hydraulic excavator has a boom, an arm, a bucket, and a boom cylinder which drives the boom. A load value within the bucket is computed based on a load of the boom cylinder, and the load value obtained by computing is corrected based on an acceleration of extension/retraction of the boom cylinder.
