A working vehicle includes a cabin and an outside air inlet portion. The working vehicle further includes: a filter device having: a first filter providing a first filtering level; and a second filter providing a second filtering level that is a filtering level higher than the first filtering level; an air conditioning unit to which the outside air having passed through the filter device is supplied; and a filter changing mechanism having: a first state to allow the outside air to pass through only the first filter; and a second state to allow the outside air to pass through at least the second filter among the first filter and the second filter, the filter changing mechanism being configured to be selectively switched to the first state or the second state.

A machine includes a chassis, a plurality of ground-engaging elements supporting the chassis above a ground surface, a motor for driving at least one of the ground-engaging elements and a plurality of assemblies supporting the chassis on the ground-engaging elements. Each of the assemblies is configured to selectively raise and lower the chassis relative to the ground surface and includes a first attachment component for attaching the assembly to one of the ground-engaging elements, a second attachment component for attaching the assembly to the chassis, an adjustment component for shifting the first attachment component between a plurality of operating positions relative to the second attachment component. A control system allows an operator to remotely control the adjustment components of each of the assemblies.

A vehicle includes a dynamic shock absorbing mechanism provided in a cabin. The dynamic shock absorbing mechanism includes a weight support member transversely supported at an upper portion of a cabin frame and extending along a transverse width of a vehicle body; and a weight member supported at a center portion in the vehicle body transverse width direction of the weight support member. The weight support member is an elastic member that has a smaller elastic modulus than an elastic modulus of the cabin frame.

A work vehicle that operates on a surface comprising an implement and a cab. The cab comprises a left side portion, a right side portion, a floor coupled to the left side portion forming a left floor edge and coupled to the right side portion forming a right floor edge, and a roof coupled to the left side portion forming a left roof edge and coupled to the right side portion forming a right roof edge. The cab further comprises a frame positioned above the floor in a central portion of the front of the cab. A first support extends from the central portion towards the left floor edge. A second support extends from the central portion towards the right floor edge. A third support extends from the central portion towards the left roof edge. A fourth support extends from the central portion towards the right roof edge.

To provide a cab in which opening and closing of a door is hardly inhibited even if a cab frame or a door is deformed. A cab comprises a cab main body having a cab frame and a doorway formed in the cab frame. The cab comprises a door that opens and closes the doorway of the cab main body. The door is installed to the cab main body so as to be opposed to the side surface of the cab frame in a closed state of the doorway.

Described is a self-propelled operating machine (1) comprising a control cabin (2) for housing an operator and a unit (3) for moving a load. The control cabin (2) comprises a supporting frame (4) and a transparent wall (7) applied to the supporting frame (4) and partly delimiting the cabin (2). The transparent wall (7) can be made opaque in a controlled manner.

A protection mechanism for a working vehicle includes a roof provided above an operator's seat, a pillar extending upward from a vehicle body and supporting the roof, a camera with a predetermined viewing direction, and a support stay which is connected to the pillar, orients the predetermined viewing direction of the camera sideways, and supports the camera below a peripheral portion of the roof. The protection mechanism includes a front pillar supporting a front portion of the roof and a rear pillar supporting a rear portion of the roof. The support stay is connected to the rear pillar.

A sensor maintenance system may include a sensor having an exterior, a heat exchanger to output exhaust air and a conduit for directing the exhaust air to regions proximate the exterior of the sensor.

Machine, especially a padding machine, for the burying of pipes, in particular arranged in a respective excavation of the ground, quali gas pipelines, oil pipelines, aqueducts, or altri, in particular for la covering of said pipe with a corresponding material, in particular un treated material, preferably screened or frantumato, including a main support framework of the apparatus, in particular which extends according to a respective longitudinal axis of the same machine, a cabin for housing the driver of the machine, such a cabin is in the form of a cabin movable with respect to said main support frame. Said cabin for housing the driver of the machine can be positioned, in corresponding vertical positions, or placed at height levels different from each other, preferably moving vertically, or perpendicularly to said ground.

A system for powering a vehicle is provided. The system can include an engine or power generation system to be powered by a fuel and a housing. The housing can be configured to couple to one or more frame rails of the vehicle, receive and protect a cylinder configured to store the fuel to be used by the engine or power generation system. The housing can have one or more access panels allowing access to an interior of the housing. The cylinder can include a first end portion, a second end portion, a central body forming an enclosed cavity for storing pressurized gas, a reinforcement structure disposed over the central body, and a metal foil interposed between the reinforcement structure and central body. The metal foil can be configured to reduce permeation of contents of the cylinder.
