A contact of an attachment with an obstacle is suppressed, and concurrently, a wasteful motion of the attachment is suppressed. When determining that an obstacle specific portion exists between a start point and an end point, a controller sets an avoidance path as a target path. The avoidance path is a path along which an attachment specific portion moves from the start point to the end point while the attachment is led to an avoidance operation of avoiding the obstacle. When determining that the obstacle specific portion does not exist between the start point and the end point, the controller sets a non-avoidance path as the target path. The non-avoidance path is a path along which the attachment specific portion moves from the start point to the end point while the attachment is not led to the avoidance operation.
A technology capable of reducing a data amount required for a estimation processing while maintaining accuracy for estimation of a virtual deformation state of an attachment which receives external force in a crane is provided. A deformation state of each of a boom (first attachment element) and a jib (second attachment element) configuring an attachment connected to a crane main body so as to perform a derricking motion is estimated according to a crane model. The crane model is a model indicating a correlation among an “acting force factor” for specifying an acting state of force on the attachment connected to the crane main body so as to perform the derricking motion, a “posture factor” for specifying respective postures of the boom and the jib, and “angle changes (elevation angle deviations Δθ1 and Δθ2)” indicating respective deformation states of the boom and the jib.

When the crane of the type satisfying specified conditions is present, information regarding the crane of the type is selectively provided to a user such as a construction work planner through a terminal output interface. A “first specified condition” included in the specified conditions is the condition of having such a load-lifting level that an interval between an upper end of a building and a lower end of a material which is a suspended load is equal to or larger than a threshold in a state where a crane is arranged at a specified place in an area around the building and an attachment is in a specified posture.

REMOTE OPERATION ASSISTANCE SYSTEM AND REMOTE OPERATION DEVICE
Provided is a system or the like which can improve the consistency between an operation direction of a remote operation mechanism by an operator and a turning direction of a working machine, which is remote and intended by the operator. While the correspondence between the operation direction of a remote operation mechanism 211 and the turning direction of a working machine 40 is adjusted, a turning command corresponding to the operation direction of the remote operation mechanism 211 is output to the working machine 40. Even though there are cases where the correspondence between the operation direction of a remote operation mechanism and the turning direction of a working machine is switched, it is required that a designated condition is satisfied for the switching. As described above, the "designated condition" indicates a low necessity for maintaining the turning direction of the working machine 40 corresponding to operation directions, to that point, of the remote operation mechanism 211 in consideration of at least one among an operation amount of the remote operation mechanism and a turning angle of the working machine.
A technology that further facilitates automatic driving control of working machines includes a working area setting system that includes an area setting unit. The area setting unit is provided to set a working area. The working area is a predetermined range in which an operation target of a working machine is stacked.

Provided is a safety device with which alerts can be issued at a preferred frequency on the basis of the presence or absence of sensed objects around a work machine. The safety device comprises a sensing unit, an alert device, an operation detector, and a control unit. The sensing unit senses sensed objects present around the work machine. The alert device issues alerts. The operation detector detects a target operation amount, which is the magnitude of an alert-targeted operation. The control unit causes the alert device to issue an operation alert only when a sensed object is present in an alert area set around the work machine and the target operation amount exceeds an allowable operation amount set in advance, and stops the issuing of the operation alert when the target operation amount is equal to or less than the allowable operation amount, regardless of sensed objects.

When a change suppression condition is satisfied, which includes the current information changing in a direction of moving further away from the work machine that the previous information, the control unit executes control change suppression for suppressing the change in the safety control corresponding to the change in the position information, and the control unit cancels the control change suppression at the point in time when a predetermined time has elapsed since the control change suppression was started.
