摘要： Provided is a construction machine capable of smooth exhaust and suppression of a leak of noise from an engine room, including an engine guard defining an engine room, a cooling fan disposed in the engine room, a projection element projecting upward beyond the engine guard, and an exhaust duct. The exhaust duct has a bent shape including a first duct section extending along an axial flow direction of the cooling fan from an upstream end portion surrounding a duct inlet to a connection portion and a second duct section extending upward from the connection portion and surrounding a duct outlet opened upward, also including an engine concealment section obstructing a direct view to an engine through the duct outlet from outside the engine room.

摘要： A work machine includes: a first posture detection device which detects a posture of an upper slewing body with respect to a lower travelling body; a second posture detection device which detects a posture of a blade; a laser beam receiver which is provided to the upper slewing body and can receive a laser beam emitted from a laser beam emitter; and a calculation unit which calculates a height position of a cutting edge of the blade with respect to a surface to be constructed. The calculation unit calculates the height position of the cutting edge of the blade with respect to the surface to be constructed based on a laser beam receiving position where the laser beam is received by the laser beam receiver, a posture of the upper slewing body with respect to the lower travelling body, and a posture of the blade.

摘要： A compaction management system includes a position calculation unit that, when a bucket is pressed against a compaction target ground, calculates a position of the bucket, a rolling compaction force calculation unit that, when the bucket is pressed against the compaction target ground, calculates a rolling compaction force applied to the compaction target ground using the attitude of the machine body, the attitude of the attachment, a pressure of a cylinder, and dimensions of the attachment, a rolling compaction record creation unit that creates a rolling compaction record in which the position calculated by the position calculation unit is associated with the rolling compaction force calculated by the rolling compaction force calculation unit, and a storage control unit that causes a storage device to store the rolling compaction record created by the rolling compaction record creation unit.

摘要： A remote operation device includes: a vibration detector to detect a plurality of vibration components in a plurality of directions different from each other, the vibration components being included in a vibration caused on an attachment; a transmission device; and a transmission control section that controls an operation of the transmission device. A vibration determination condition is set in advance, the vibration determination condition including a condition that an amplitude of a maximum vibration component largest in amplitude among the plurality of vibration components detected by the vibration detector is equal to or larger than a preset amplitude threshold. The transmission control section controls the operation of the transmission device to allow the vibration information to be transmitted to an operator only when the vibration determination condition is met.
