A work vehicle, comprises: an operation section occupiable by an operator; a cabin accommodating the operation section; left and right suspension mechanisms via which a body of the work vehicle supports a left portion and a right portion of the cabin; and left and right lateral rods configured to allow the cabin to move upward and downward relative to the body and restrain the cabin from moving leftward and rightward relative to the body.

A suspension system for a cabin of a mining vehicle. The suspension system comprises a plurality suspension units to support the cabin with respect to the mining vehicle. At least two of the suspension units are pivot suspension units, and each pivot suspension unit is pivotably mountable to the cabin and is fixedly mountable to the mining vehicle. The cabin is pivotable relative to the mining vehicle about a common pivot axis defined by the pivot suspension units. Each pivot suspension unit has an attenuation member to attenuate a pivot movement of the cabin relative to the mining vehicle. An underground mining vehicle and a cabin for a mining vehicle are also disclosed.

A work vehicle has a cabin 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, said position being located outward of the anti-vibration member, with the weight member protruding to the vehicle body outer side from the bracket.

A vibration dampening mount assembly includes a housing, resilient material, a sleeve and a restricting structure. The resilient material is fixedly attached to an interior surface of the housing and defines a first chamber and a second chamber. The sleeve is disposed within the housing and is centrally attached to the resilient material. The restricting structure between the first chamber and the second chamber includes a first portion attached to the housing and a second portion attached to the sleeve. In response to movement of the sleeve relative to the housing, the second portion of the restricting structure moves relative to the first portion. The first portion and the second portion of the restricting structure define a fluid passageway therebetween. The cross-sectional area of the fluid passageway changes in response to movement of the second portion relative to the first portion.

A working vehicle includes a suspension including a damper to suppress vertical motion of a cabin over a vehicle body, and a restrictor to restrict the cabin at an upper limit position and/or a lower limit position. The restrictor includes a first stopper fixed to the vehicle body, and a second stopper fixed to the cabin. At least one of the first stopper or the second stopper includes a first cushion portion, and a second cushion portion softer than the first cushion portion. The first cushion portion and the second cushion portion are adjacent to each other in a direction intersecting a vertical direction, and the second cushion portion is contactable with a target of contact before the first cushion portion.

An operator ride enhancement system that is coupleable to the frame of a vehicle includes a counterweight platform moveably coupled to the frame, and a resilient member engaged with the frame and the counterweight platform. The mass of the counterweight platform is configured to be approximately at least equal to a total mass supported by the counterweight platform during operation of the vehicle. The operator ride enhancement system attenuates and/or inhibits movement of the counterweight platform during operation of the vehicle.

A fluid-filled tubular vibration-damping device comprising: an inner shaft member and an outer tube member connected by a main rubber elastic body so as to provide a sealed zone filled with a non-compressible fluid therebetween; and a partition wall partitioning the sealed zone axially. An outer peripheral side of the partition wall is fixed to the outer tube member while an inner peripheral side of the partition wall is constituted by an annular partition wall rubber disposed around the inner shaft member in a movable manner axially. Sealing tube parts are integrally formed with an inner peripheral portion of the partition wall rubber and project toward axially opposite sides. Fitting parts thicker than the sealing tube parts are integrally formed with distal ends of the respective sealing tube parts and are externally fitted around the inner shaft member in a slidable manner.

A vehicle cab suspension is provided with a body having a mounting member positioned at least partially within the body. One or more resilient members connect the body to the mounting member and are placed in a compressed condition between the body and the mounting member when the vehicle cab suspension is in an unloaded condition. The body may be formed of first and second body pieces, each of which may be provided with upper and/or lower projections to restrict movement of the resilient members during use.

A cabin suspension arrangement for a utility vehicle, having a plurality of trailing arms that extend in a longitudinal direction, by which a driver's cabin is mounted and can pivoted relative to a vehicle frame. Two of the trailing arms are arranged spaced apart from one another in a transverse direction that extends perpendicularly to the longitudinal direction, are connected to one another by a torsion bar spring that extends in the transverse direction, and are arranged at the same height in a vertical direction perpendicular to the longitudinal direction and to the transverse direction, thereby forming a first trailing arm pair. Two other trailing arms are arranged spaced apart from one another in the transverse direction, are arranged at the same height in the vertical direction, and thereby form a second trailing arm pair, which is spaced apart, in the vertical direction, from the first trailing arm pair.

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.
