Abstract: A hydraulic tilting device for tilting a cab of a vehicle between a driving position and a tilted position, which cab is resiliently supported on the chassis of the vehicle. The tilting device includes a reservoir for hydraulic fluid and a pump which is connected to the reservoir. The tilting device also includes a double-acting hydraulic tilting cylinder for tilting the cab. At the tilting cylinder there is a lost-motion passage which extends between ports which open out into the cylinder space of the tilting cylinder, which ports are respectively in communication with the pressure chamber and the pull chamber of the tilting cylinder if the piston-piston rod assembly is in the lost-motion range defined by the ports. The tilting device is designed in such a manner that the reciprocating movements of the piston-piston rod assembly within the lost-motion range can take place with as little obstacle as possible.

Abstract: A hydraulic tilting device for tilting a cab mounted on the chassis of a vehicle between a driving and a tilted position comprises a reservoir for hydraulic fluid, a pump connected to the reservoir, and a double-acting hydraulic tilting cylinder. A lost-motion conduit is provided between ports opening into a push chamber and a pull chamber in the cylinder space of the tilting cylinder when the piston/piston rod assembly is in a lost-motion range defined by the ports. When under the influence of the movements of the piston/piston rod assembly within the lost-motion range, the pull connection of the tilting cylinder causes suction of hydraulic fluid out of the reservoir, forcing hydraulic fluid from the reservoir into the pull chamber, and moving hydraulic fluid from the pull chamber to the reservoir through the lost-motion conduit. Hydraulic fluid therefore circulates when the cab is carrying out spring movements.

Abstract: A transportation vehicle for transporting an individual over ground having a surface that may be irregular. The vehicle has a support platform for supporting the subject and the support platform is coupled to a ground-contacting module at a pivot. While the ground-contacting module may be statically stable, balance of the support platform with respect to the ground-contacting module is maintained by motion of the ground-contacting module in response to leaning of the support platform. A motorized drive coupled to the ground-contacting module causes locomotion of the vehicle and the subject therewith over the surface, while a control loop, in which the motorized drive is included, dynamically enhances stability in the fore-aft plane by operation of the motorized drive in connection with the ground-contacting module. In the event of failure of the control loop, the pivot connection of the support platform to the ground-contacting module may be locked, thereby ensuring stability of the static assembly.

Abstract: The invention related to a process for suspending on a vehicle frame a driving cab which has two-point suspension. Assembly involves the cab being lowered towards the frame by means of a lifting device so that a contact device fitted to the cab is caused to rest on the portions of a supporting device which protrude on either side of a supporting unit mounted on the frame. This means that the cab lies in a stable manner against the frame and that the fastening apertures of the contact device and of the supporting device are placed centrally to one another. The lifting device can therefore be released and the contact device be secured to the fastening device, thereby fixing the contact device relative to the supporting device but leaving the supporting device freely rotatable in the supporting unit.

Abstract: There is provided a cab structure that a joint portion of a cab and a chassis frame has sufficient shear strength and which can disperse external force to the entire cab or chassis frame to reduce the burden of load and can sufficiently resist the impact load in the longitudinal direction. A front end portion of a cab-under-frame fixed to the outer surface of the floor panel is extended toward a front upper side, and a cab mount bracket is also extended toward a front upper side so that they are integrally joined with a front mounting rail. As a result, these three components are firmly fastened to disperse the incoming force in the longitudinal direction.

Abstract: The present invention is directed toward a stabler leveling mechanism for tree harvesters. The present invention utilizes many of the same components of conventional leveling mechanisms for tree harvesters, but it alters the pivot axis of a swing-house assembly. A conventional swing-house assembly pivots about an axis parallel to the top surface of a carriage on level ground. That conventional assembly can be deleterious, therefore, applicant has altered the pivot axis of the swing-house assembly. Admittedly, merely moving the pivot axis seems simple but it is difficult. The components had to be constructed differently to obtain the desired results and simultaneously make the device stable within the working environment.

Abstract: A vehicle cab is resiliently suspended on a vehicle frame. Between the cab and the frame is arranged a device for limiting the mobility of the cab relative to the frame during operation and upon tilting of the cab. The device incorporates two stop surfaces fastened to the cab, and a movement limiter fastened to a stabilizer which is fastened to the frame. The movement limiter extends between the stop surfaces so that it shifts between them upon movement of the link arms. The cab's mobility is limited by the fact that contact occurs between the movement limiter and the stop surfaces.
