The present disclosure relates to a structure for mounting an upper cabin suspension bracket, the structure configured to connect the upper cabin suspension bracket to a main sill front, wherein an upper cabin suspension bracket mount member for mounting the upper cabin suspension bracket is fixed to integrally form a closed curved surface from the bottom of the main sill front to a front side of a dash member.

A working vehicle is provided with a cabin which covers a control seat on a travel machine body. The cabin has a cabin frame which constructs a framework. At least one frame member of the cabin frame is formed into a C-shaped cross section. A reinforcing plate extending along a longitudinal direction of the frame member is fixed by welding to an opening portion of the frame member. At least longitudinally intermediate portion of the frame member is formed into a hollow shape.

Provided is a frame structure for a vehicle including: a pair of main side rails which extends in the vehicle longitudinal direction and faces each other; and an extension side rail which is connected to a front portion of the main side rail in the vehicle longitudinal direction and extends in the vehicle longitudinal direction, wherein the extension side rail is formed so as to have a substantially C-shaped cross-section and is formed so that a front portion is lower than a rear portion in the vehicle longitudinal direction.

An agricultural vehicle including a supporting structure and a coupling system connected to the supporting structure for the movable coupling of a vehicle cab to the supporting structure. The coupling system includes at least one spring-elastic bearing element. The vehicle cab releasably connects via at least one clamping element to the at least one spring-elastic bearing element. A clamping force direction of the clamping element runs transversely to a vehicle vertical axis in a transverse direction.

The invention relates to a damping system for a cabin of a movable work machine, wherein the cabin is supported to the frame of the work machine with suspension elements, the suspension elements forming a ROPS resistant structure and including: a first for fastening the cabin to the first end of the suspension element, a second stopper for fastening the frame to the second end of the suspension element, a guide element comprising a slide guide and a support arm, the slide guide and the support arm being arranged to move relative to each other, and the guide element having opposite ends, one of which is in the slide guide and the other is in the support arm, and one opposite ends is mechanically bound to the first end and the other is mechanically bound to the second end, a spring element, and a damping element.

The invention relates to a vehicle seat or a vehicle cab with a suspension system comprising an upper closing part and a lower closing part which is deflectable in relation to the upper closing part, which closing parts are connected to each other in a resilient manner by means of a suspension element, and with a damping system for damping vibrations acting on at least one of the two closing parts, wherein the damping system and a distance levelling system for adjusting a distance between the upper closing part and the lower closing part have a common fluid actuator element controlled by compression and tension stages.

Disclosed is a work vehicle in which a cabin is supported via an anti-vibration member to a bracket that extends to a vehicle body outer side from a vehicle body frame. The bracket mounts a weight member. The weight member is attached to a position in the bracket which position is on more outer vehicle body side than the anti-vibration member, with the weight member protruding to the vehicle body outer side from the bracket.

An agricultural harvesting machine a chassis, a cabin and at least one mount coupling the cabin to the chassis. The mount has a first connecting feature connected to the cabin, a second connecting feature connected to the chassis and a resilient member coupled to both the first connecting feature and the second connecting feature. The resilient member has a shaped void therein.

A regulation device including a stopper receiving part mounted on the machine frame and/or the bottom of the cab includes a through hole formed at the center part, a shaft penetrating the through hole of the stopper receiving part and a stopper supported by the shaft. A spherical surface is formed on the side surface of a stopper where a stopper receiving part contacts. When the cab displaces in the direction away from the machine frame, the spherical surface of the stopper contacts in vicinity of a through hole of the receiving part to inhibit detachment.

A standing platform for an industrial truck includes a spring arrangement abutting the platform when subject to a weight. A first spring section with a soft characteristic is initially deformed under load, and after a predetermined spring path of the first spring section, a second spring section with a harder spring characteristic is deformable. A sensor detects deformation of the first spring section for generating a release signal. The platform can be folded on a horizontal shaft including a lever arm arranged on a side of the shaft opposite the platform, and abuts the spring arrangement from below which is supported on the truck frame. The first spring section is arranged between a seat for the first spring section and a spacer supported on the second spring section. The spacer acts on the second spring section when the first spring section is initially deformed under a load upon the platform.
