Provided is a work machine (100), wherein: a fuel pipe (40A) is disposed at a position offset from a space (50S) between high-voltage devices which are a first high-voltage device (51) and a second high-voltage device (52) of a high-voltage device group (50), and a space (60S) between hydraulic devices which are a first hydraulic device (61) and a second hydraulic device (62) of a hydraulic device group (60); a high-voltage cable (50A) is disposed at a position offset from a space (40S) between fuel devices which are a fuel tank (41) and a fuel cell device (42) of a fuel device group (40), and the space (60S) between hydraulic devices; and a hydraulic pipe (60A) is disposed at a position offset from the space (40S) between fuel devices and the space (50S) between high-voltage devices.
B60L 50/70 - Electric propulsion with power supplied within the vehicle using propulsion power supplied by batteries or fuel cells using power supplied by fuel cells
A work machine (100) comprises: a hydrogen tank (31) that stores hydrogen; an energy generation device (32) that is disposed below the hydrogen tank (31) and generates energy using the hydrogen as an energy source; a hydrogen pipe (41) that connects the hydrogen tank (31) and the energy generation device (32); and a support structure (60) that supports the hydrogen tank (31) and/or the energy generation device (32). The support structure (60) includes an intervening portion (63, 206, 208, 306, 802) located between the hydrogen tank (31) and the energy generation device (32), the intervening portion having a guide portion (63C, 210A, 210B, 308, 804) for guiding the hydrogen from a position below the intervening portion to above the intervening portion.

E02F 9/08 - SuperstructuresSupports for superstructures
F01P 3/18 - Arrangement or mounting of liquid-to-air heat-exchangers
F02M 21/02 - Apparatus for supplying engines with non-liquid fuels, e.g. gaseous fuels stored in liquid form for gaseous fuels
Provided is a monitoring area setting system that can reduce an amount of calculation required for monitoring. A monitoring area setting system includes a point cloud data acquisition unit and a controller. The point cloud data acquisition unit has a preset detection range, and acquires point cloud data that is data indicating a distance from a predetermined reference point to a target object within the detection range. The controller acquires information on a reference monitoring area that is an area set to include a work machine located within the detection range, identifies an operation range of the work machine as an excluded area based on the point cloud data, and sets an actual monitoring area for the work machine by excluding the excluded area from the reference monitoring area.
A controller of a driving device sets a target physical quantity relating to an orientation of a work device, calculates a current physical quantity relating to the actual orientation of the work device, calculates a physical quantity error between the target physical quantity and the current physical quantity, calculates an assistance operation value for assisting operation of an operator, corrects an operator operation value to an operator correction value so as to attain a small value when the physical quantity error is small as compared with when the physical quantity error is large, corrects the assistance operation value to an assistance correction value so as to attain a large value when the physical quantity error is small as compared with when the physical quantity error is large, and controls the orientation of the work device using a total value obtained by adding the operator correction value and the assistance correction value.
