An all-terrain telehandler includes a pair of front tracks. Each front track may be coupled to a front bracket by an arm that telescopes relative to the front bracket. A superstructure may be coupled to the front bracket where the superstructure supports a first telescoping boom. A pair of rear tracks may be coupled to a rear body. The rear body may be coupled to the front superstructure. A maximum extension position for the first telescoping boom and a length generally corresponding to a length of the superstructure may define a ratio of approximately 4.00:1.00, whereby the all-terrain telehandler is substantially stable when moving loads supported by the first telescoping boom. A second telescoping boom may support a cab. With the second boom, the cab may be lowered beneath a top section of one of the front tracks for facilitating an operator loading sequence.

The invention relates to a lifting machine (1) comprising a lifting arm (3), a rolling chassis (2) equipped with at least one front axle (5) and one rear axle (6), and a sensor for measuring the tilt of the lifting arm (3) in relation to the chassis (2), the rear axle (6) being pivotably mounted around an axis that is parallel to the longitudinal axis of the machine (1). The rear pivoting axle (6) is mounted to freely pivot inside an angular range defined by two abutments supported by said chassis (2), the front axle (5) is coupled to the chassis (2) by a pivoting connection with an axis that is parallel to the longitudinal axis of the machine (1) and is equipped with an activatable/deactivatable suspension (9) in order to allow the relative pivoting between the front axle (5) and the chassis (2) to be damped, said suspension (9) being deactivated at least when the angle value measured by sensor (4) for measuring the tilt of the lifting arm (3) is greater than a predetermined threshold value.

The invention relates to a hydraulic system for controlling or regulating a hydraulic cylinder comprising—at least one hydraulic cylinder, at least one hydraulic unit by means of which the hydraulic cylinder can be optionally connected to a pressure source and a tank and at least one control or regulating device for controlling or regulating the supply of hydraulic fluid to the hydraulic cylinder, the control or regulating device forms a first assembly and the hydraulic unit forms a second assembly which are structurally separate from one another and fluidically connected, wherein the supply of hydraulic fluid to the hydraulic cylinder can be predominantly controlled or regulated by the control or regulating device from outside the hydraulic unit and wherein the hydraulic unit is rigidly fastened on the hydraulic cylinder.

A load wheel assembly is provided comprising: a frame member; a side plate coupled to the frame member; an axle extending between the frame member and the side plate; and a keeper coupled by a fastener to the frame member or the side plate. The keeper is coupled to one end of the axle to prevent rotational and axial movement of the axle relative to the frame member and the side plate.

A transport vehicle for transporting payloads is provided. The transport vehicle includes primary and secondary chassis, and first and second sets of wheels for supporting the respective primary and secondary chassis. A guide arrangement is mounted on the primary chassis and the secondary chassis is slidably mounted on the guide arrangement. The primary and secondary chassis are parallel and spaced apart from each other. A payload lifting arrangement is positioned on a top surface of the secondary chassis to lift a payload. When a weight of the payload is below or equal to a threshold weight, the weight is distributed across the second set of wheels by way of the suspension arrangement. When the weight of the payload exceeds the threshold weight, the weight is distributed across the first and second sets of wheels by way of the guide arrangement and the suspension arrangement, respectively.

A material handling vehicle is provided. The material handling vehicle includes a vehicle frame having a drive wheel and an offset wheel arranged under the vehicle frame. The material handling vehicle further includes a rear load wheel assembly pivotally coupled to the vehicle frame via an articulating axle assembly. The rear load wheel assembly includes a first load wheel and a second load wheel. The pivotal coupling between the rear load wheel and the vehicle frame provided by the articulating axle assembly is configured to maintain the drive wheel and the offset wheel in contact with a floor on which the drive wheel and the offset wheel travel.

A leveling system for a lift device includes a control system. The control system has programmed instructions to acquire operation data regarding operation of the lift device, fluidly couple a first leveling actuator and a second leveling actuator based on the operation data, acquire an update regarding the operation data, fluidly decouple the first leveling actuator and the second leveling actuator based on the update regarding the operation data, and selectively control the first leveling actuator and the second leveling actuator to (i) selectively reposition a first tractive element and a second tractive element relative to each other about a longitudinal axis defined by the lift device and (ii) selectively reposition the first tractive element and the second tractive element about a first lateral axis defined by the lift device.

An autonomous guided vehicle comprising a platform adapted to carry load thereon in a working position; a plurality of suspension devices connected to the platform, each suspension device having a sensor and an actuator; and a plurality of wheels associated with the suspension devices; wherein a first wheel is associated with a first suspension device such that the sensor of the first suspension device is adapted to provide a sign when a relative position of the first wheel and the platform is altered.

The industrial vehicle includes a body, an axle, a lateral acceleration sensor determining lateral acceleration, an actuator temporally restricting pivoting of the axle, a vehicle speed limiter limiting vehicle traveling speed, and a controller driving the actuator based on the lateral acceleration determined by the lateral acceleration sensor to temporally restrict pivoting of the axle while the industrial vehicle is being turned and to limit traveling speed of the industrial vehicle based on lateral acceleration determined by the lateral acceleration sensor when the industrial vehicle is turned. A first lateral acceleration threshold value which is used in judging whether traveling speed of the industrial vehicle should be limited is set smaller than a second lateral acceleration threshold value which is used in judging whether pivoting of the axle should be temporally restricted. An upper limit deceleration rate is set for limiting the traveling speed of the industrial vehicle.

The invention relates to a chassis comprising a base (12) and four wheels (14) each being mounted on the base by way of a respective supporting device (16) and each being capable of being brought out of a transport position into an operating position of the chassis (10), and vice versa, wherein each supporting device comprises a support or carrier arm (18), which is arranged on the base via a proximal end (20) to be pivotable out of the transport position into the operating position of the chassis, and vice versa, and at a distal end (22) receives an axle journal (24) for rotation, a first control (30) for pivoting the support or carrier arm out of the transport position into the operating position of the chassis, and vice versa, the axle journal rotatably arranged at the distal end of the support or carrier arm, a stub axle (40), which is pivotably arranged on the axle journal and receives the wheel for rotation at a distal end (42) of the axle journal; and a second control (44) for pivoting the stub axle against the axle journal.
