A distance detection unit detects a first distance from a specific reference position associated with a work machine to a portion of a platform of a carrier on a carrier rear side, and a second distance from the reference position to a portion of the platform on a carrier front side. A controller causes a stop instruction output unit to output a stop instruction at least either when the first distance falls from a value greater than a first threshold value to a value equal to or smaller than the first threshold value or when the second distance falls from a value greater than a second threshold value to a value equal to or smaller than the second threshold value.
A target path changing system for an attachment, which is capable of improving the working efficiency of an operation to change a target path of a specific part of the attachment, is provided. An object point selection unit is configured to allow an operator to select one of target points as a change object point. A range setting unit is configured to set a movable range in which the change object point is movable. An object point movement unit allows the operator to move the change object point within the movable range. A target path resetting unit is configured to reset a target path between a change start point and a change end point so that the target path passes through an after-movement change object point.

CRANE AND METHOD FOR ASSEMBLING AND DISASSEMBLING CRANE
Provided are a crane capable of improving the operability for lowering and raising a strut, and a method for assembling and disassembling the crane. The crane comprises: a boom (24) including a boom leading end section; a jib (25) including a jib base end section; a strut (27) that can be hoisted by being coupled to the boom leading end section or the jib base end section and rotated vertically about a strut center of rotation; a winch; a winch rope (32) wound and let out by using the winch; and a strut support unit (2) attached to the back surface of the jib or the front surface of the strut. The strut support unit (2) supports the strut (27) when the strut (27) is in a lowered posture in a state in which the boom and jib are lowered, and at a position where the strut (27) can be hoisted on the jib (25). In the position where the strut (27) can be hoisted, a rope connection location where the rope (32) is connected on the strut (27) is in a position higher than the strut center of rotation.
B66C 23/26 - Cranes comprising essentially a beam, boom or triangular structure acting as a cantilever and mounted for translatory or swinging movements in vertical or horizontal planes or a combination of such movements, e.g. jib cranes, derricks or tower cranes specially adapted for use in particular locations or for particular purposes for use on building sitesCranes comprising essentially a beam, boom or triangular structure acting as a cantilever and mounted for translatory or swinging movements in vertical or horizontal planes or a combination of such movements, e.g. jib cranes, derricks or tower cranes specially adapted for use in particular locations or for particular purposes constructed, e.g. with separable parts, to facilitate rapid assembly or dismantling, for operation at successively higher levels, for transport by road or rail
Provided are a crane with which it is possible to improve operability in terms of connecting a guy-line for linking a strut and a boom together to the boom, and a crane assembly method. A rope distal-end part of a winch rope (32) is connected to an intermediate member (4) in a state in which a boom (24) and a jib (25) are toppled on the ground. A winch carries out a winding operation to wind the winch rope (4), as a result of which a toppled strut (27) is caused to rise and the intermediate member (4) approaches a guy-line connection part (51) of the boom, making it possible for a boom connection end part of a second guy-line (3) that is connected to the intermediate member (4) to be connected to the guy-line connection part (51).

A position detection system includes: a mark provided on a detection target; an imaging device that images the detection target so as to include the mark; an acquisition unit that acquires a position and an attitude of the mark from imaging information that is information related to the mark imaged; a storage device that stores information on a three-dimensional shape of the detection target; and a detection target calculation unit that calculates a position and an attitude of the detection target based on mark related information that is information related to acquired position and attitude of the mark and stored information on the three-dimensional shape of the detection target.
A speed compensation part included in a construction machine executes a feedback control of regulating an opening degree of a second control valve to an opening degree obtained by subtracting a correction amount from a second target opening degree of the second control valve, when a combined manipulation is performed and a preset load determination condition is satisfied. The correction amount is calculated by the speed compensation part so as to be larger as a speed difference between a first target speed and a first actual speed becomes larger, the first target speed being a target speed of a first actuator and determined on the basis of a manipulation amount of a first instructive manipulation, the first actual speed being an actual speed of the first actuator.
The present invention acquires a plurality of images of the external world as viewed from a slewing structure of a work machine that are arranged in time series and are generated by an imaging unit that is provided so as to move along with the slewing of the slewing structure. For each image from among the plurality of images, the image and an image that immediately precedes the image in the time series are referred to to determine a first slewing angle of the slewing structure with reference to the position of the slewing structure relative to a base body in the first image among the plurality of images. On the basis of the plurality of first slewing angles determined for the plurality of images, a predetermined point in the external world is determined as a reference for the slewing angle. For each image from among the plurality of images, the first slewing angle determined for the image and the reference are referred to to determine a second slewing angle of the slewing structure relative to the reference.
