The housing has a first side surface which is disposed on the upstream side of the air flow, a second side surface which is disposed on the downstream side of the air flow, and a third side surface which is connected to the first side surface and the second side surface. The vehicle body is provided with a first passage which is disposed on the side of the first side surface, a second passage which is disposed on the side of the second side surface and on an outer edge of the vehicle body in a top view, and a third passage which is disposed on the side of the third side surface and is connected to the first passage and the second passage.

Provided is a waterproof structure to prevent water ingress through an air hole in a casing of a communication device. A waterproof structure for a communication device, the communication device including a casing that houses an electronic substrate and has an air hole, includes a plate member facing the casing and attached to the casing such that the plate member covers the air hole, and a sealing member interposed between the plate member and the casing to prevent ingress of water into the air hole through a gap between the plate member and the casing.

An opening and closing mechanism for a vehicle body cover which is attached to and detached from a vehicle body of a working vehicle in a separable manner includes a latching portion configured to latch an upper portion of the vehicle body cover to the vehicle body, and a lock portion configured to lock a lower portion of the vehicle body cover to the vehicle body, wherein the lock portion includes a striker provided at the vehicle body cover, a hook provided at the vehicle body, the striker being engageable with and disengageable from the hook, and a lock release portion configured to release a state of the striker being engaged with and locked by the hook, and wherein the lock release portion is arranged at a position which, when directly facing an opening portion provided at the vehicle body, is not viewable inside a field of view of the opening portion and which is graspable by a worker putting a worker's hand inside from the opening portion and stretching worker's fingers from inside the field of view of the opening portion to outside the field of view of the opening portion.

A hydraulic tank for a machine is disclosed herein. The hydraulic tank includes a casing defining an interior space and having an outer surface, an inner surface opposite the inner surface, and a return hydraulic fluid inlet extending through the casing. A first concave member is connected to the inner surface of the casing to form a passage. The passage is positioned and shaped to transport hydraulic fluid from the return hydraulic fluid inlet to another location within the hydraulic tank.

An electric construction machine includes a driving system configured to drive a machine body under electric power, a heat exchange device configured to exchange heat of a cooling medium for cooling the driving system, a cooling fan configured to send air for cooling the heat exchange device, and a cooling fan control unit configured to control the rotation of the cooling fan according to a set operating mode. The operating mode includes a driving mode in which the driving system is driven and a charging mode in which the driving of the driving system is stopped to charge a battery configured to store electric power. The cooling fan control unit is configured to set the rotation rate of the cooling fan in the charging mode to a charging mode rotation rate that corresponds to the driving state of the driving system.

A work machine includes: a vehicle body front part to which a front wheel is attached; a vehicle body rear part which is coupled to the vehicle body front part through an articulated mechanism and to which a rear wheel is attached; a working equipment coupled to the vehicle body front part; a headlight supported by the vehicle body front part and arranged above the front wheel; and a three-dimensional measurement device arranged on an outer side of the headlight in a vehicle width direction that is in parallel with a rotation axis of the front wheel.

A skid steer loader includes a chassis frame, a cab, a main beam, and a bucket. The chassis frame is assembled with a walking system to form a movable chassis of the skid steer loader, and a power system of the skid steer loader is assembled to a tail portion of the chassis frame. The cab is arranged on a front portion of the chassis frame in an. overturning manner, and the cab is horizontally placed on the chassis frame when a telescopic support rod is in a retracted state and overturns forward when the telescopic support rod is in an extended state. A tail end of the main beam is movably hinged to the tail portion of the chassis frame by a four-bar linkage mechanism, the bucket is assembled to a front end of the main beam.

A hose guard for a skid loader attachment includes an axial elongate rigid enclosure defining a central cavity, the elongate rigid enclosure having an opening at a first end and an opening at a second end. A first attachment means at the first end of the elongate rigid enclosure is configured to secure the first end of the elongate rigid enclosure to the skid loader. A second attachment means at the second end of the elongate rigid enclosure is configured to secure the second end of the elongate rigid enclosure to the skid loader whereby the elongate rigid enclosure is readily attachable and removable from the skid loader facilitating removing and exchanging different skid loader attachments, and the elongate rigid enclosure has limited freedom of motion during operation of the skid loader and attachment.

Systems to control movement of a motor grader include a sensor for providing a bounce signal indicative of a bouncing movement of the motor grader, and a controller programmed with instructions that, when executed: receive the bounce signal from the sensor; analyze the bounce signal from the sensor; determine whether the maximum amplitude of the bouncing movement exceeds a threshold; in response to determining whether the maximum amplitude exceeds the threshold, generate an articulation angle command signal to change an articulation angle of the motor grader; and transmit the articulation angle command signal to change the articulation angle.
