摘要： The invention addresses the problem of providing a work vehicle that can prevent mistakes and confusion in primary settings even when a plurality of operators each operate a remote operation terminal. This work vehicle (crane 1) comprises a work device 40 that is operable using a remote operation terminal 13, wherein a primary setting of the work device 40 can be changed with the remote operation terminal 13 and when one of the plurality of remote operation terminals 13 changes a primary setting, the change is reflected in the other remote operation terminals 13.

摘要： Provided are a crane and a path generation system that can generate a transport path capable of avoiding an obstacle even if the obstacle moves. The crane (1) includes a boom (7) and a hook (10) suspended from the boom (7) by a wire rope (8) and transports a load (W) in a state in which the load W is suspended from the hook (10), the crane (1) being equipped with a sensor (camera (55)) that detects the position of an obstacle (worker X), and a control device (20) that generates a transport path CR by arranging a plurality of node points P(n) in an area containing a lifting-up point (Ps) and a lifting-down point (Pe) of the load W and connecting the node points P(n). The control device (20) generates a new transport path (CR) after increasing the number of node points P(n) arranged around the obstacle (X) when the sensor (55) detects movement of the obstacle (X).

摘要： The present invention addresses the problem of providing a crane with which it is possible to transport a load on an optimal transport path in consideration of actuation conditions of an actuator. The present invention provides a crane (1) in which a boom (9) that is capable of derricking and extending/retracting is provided to a swiveling base (8), wherein the crane (1) comprises: an operable-range-setting unit (32a) that sets an operable range (Ar) in which a load (W) being transported can be transported, the operable range (Ar) being set according to the weight (Wg) of the load (W); a path generation unit (32b) that generates, within the set operable range (Ar), a plurality of nodes P(n) through which the load (W) can pass and a plurality of paths R(n) connecting adjacent nodes P(n); and a transport path determination unit (32c) that determines a transport path (CR) of the load (W) on the basis of a priority sequence for actuating a plurality of actuators of the crane (1), the transport path (CR) satisfying a prescribed condition, and being determined from the generated plurality of nodes P(n) and plurality of paths R(n).

摘要： Provided is a crane capable of eliminating the need for a slip ring by performing power feeding and wireless communication between a traveling body and a turning body, and solving the problem associated with the use of the slip ring. A crane comprising a traveling body and a turning body turnably supported by the traveling body, the crane performing power feeding and communication between the traveling body and the turning body. The traveling body is provided with: a power supply; a lower controller which controls the traveling body and transmits power to the devices included in the traveling body; and a lower transmitter-receiver which wirelessly transmits and receives the power and data signal from the power supply. The turning body is provided with: an upper controller which controls the turning body and transmits power to the devices included in the turning body; and an upper transmitter-receiver which wirelessly transmits and receives the power and data signal to and from the lower transmitter-receiver.
