A work vehicle includes: a cab to be boarded by an operator, the cab including a roof; and a first antenna mounted on the roof. The first antenna is positioned selectively at one of a position lower than a topmost portion of the roof, and a position protruding upward relative to the topmost portion of the roof.

Work vehicle

A cab is used in a work machine. The cab includes a first pillar, a second pillar disposed to a rear of the first pillar, a beam disposed between the first pillar and the second pillar, and a reinforcing member provided to the beam.

Cab and work machine

A cab includes a dash panel disposed frontward of an operator's seat, and a monitor device disposed above the dash panel. The whole of the monitor device in the right-left direction overlaps a first front window when the monitor device is seen in the front-rear direction. The monitor device is disposed at a position at which the whole of the monitor device overlaps the first front window when the monitor device is seen in the front-rear direction.

Cab and work vehicle

A work vehicle has a cab. A protruding portion is located on an upper side of the cab and protrudes rearward relative to a rear portion of the cab. A surveillance camera is arranged on a rear side of the protruding portion. A surveillance camera is arranged above the surveillance camera, and an optical axis is inclined posterosuperiorly relative to an optical axis of the surveillance camera.

A center pillar () has a pipe structure having a hollow space (). In the center pillar (), a lower end opening () for connecting the hollow space () to an outdoor space and an upper end opening () for connecting the hollow space () to an indoor space () are formed. The lower end opening () and the upper end opening () are arranged at a prescribed distance from each other in a longitudinal direction of the center pillar (). Thus, a cab for work vehicle and a work vehicle capable of preventing dust, water, or the like from entering the cab and realizing an environment in the cab comfortable for an operator are obtained.

Cab for work vehicle and work vehicle

A rear portion is arranged in the rear of a front portion, and has a width smaller than a width of the front portion in a plan view. A wall portion extends from the rear portion outward in a width direction toward the front portion and includes two walls opposed to each other in a fore/aft direction with a gap lying therebetween, in a plan view. Electric components are arranged in the gap and project into an indoor space of a cab from the gap through a through hole formed in the front wall. In a plan view, a foremost portion of the electric components is located in the rear of a foremost normal located foremost among normals to a line connecting a front end and a rear end of a doorway, which intersect with the front wall.

Work vehicle and cab for work vehicle

An engine () is attached to a vehicle frame () on a front end side relative to a cab (). An engine cooling module () serves for cooling the engine () and it is attached to the vehicle frame () at a rear end. In a top plan view, the cab () has a projection portion projecting outward from the vehicle frame (). The cab () has a through hole (to) opening into an outdoor space of the cab () and an opening () communicating with the through hole (to) and opening into an indoor space (), and the through hole (to) opens in a lower surface of the projection portion. Thus, a work vehicle capable of preventing dust, water, or the like from entering the cab and realizing an environment in the cab comfortable for an operator is obtained.

The operator's cabis provided with a floor framehaving an opening for maintenancelocated at a floor baseand a lid bodyfor closing the opening for maintenance. The lid bodyincludes an upper inspection coverand a lower inspection coverwhich are aligned in a vertical direction with spacing so as to be attachable and detachable relative to the opening for maintenance. Disposed in a space between the upper inspection coverand the lower inspection coveris a floor ductthat can be disassembled and is provided for circulating supply air sent from an air conditioner

Operator's cab for a work vehicle

A work vehicle includes a cab, an air conditioner casing, an air conditioner unit and a rear monitoring camera. The air conditioner casing is attached to a rear upper part of the cab and includes a downwardly opened recess on a bottom face thereof. The air conditioner unit is accommodated in the air conditioner casing. The rear monitoring camera includes a main body accommodated in the recess of the air conditioner casing.

Work vehicle equipped with rear monitoring camera apparatus

The work machine has an operator's cab, an engine hood, an exhaust pipe, a first headlight, and a second headlight. The engine hood is disposed in front of the operator's cab. The exhaust pipe projects upwards from the engine hood. The first headlight and the second headlight are provided at a front part of the operator's cab spaced in a lateral direction and disposed so that optical axes of the first and second headlights are mutually intersect but not to overlap with the exhaust pipe when viewed in a top plan view.
