A leveling system for a lift device includes an axle, a pin, a cradle, and a chassis. The axle is configured to rotatably couple with one or more tractive elements. The pin extends through a bore of the axle. The cradle is pivotally coupled with the pin. The chassis is pivotally coupled with the pin and includes a first actuator and a second actuator. The first actuator and the second actuator each include a body and a rod configured to extend relative to the body. The rods of the first actuator and the second actuator are configured to be extended to engage corresponding surfaces on opposite sides of the cradle. The cradle and the chassis are configured to rock in unison a limited angular amount relative to the axle.

A vehicle system includes a controller. The controller is configured to be communicably coupled to a plurality of actuators of a vehicle that facilitate repositioning a plurality of tractive elements coupled to a chassis of the vehicle. The controller is configured to (i) control the plurality of actuators to selectively reposition each of the plurality of tractive elements through a range of motion to attempt to maintain the chassis level and (ii) drive each of the plurality of actuators toward a mid-stroke position while continuing to attempt to maintain the chassis level and while the vehicle is moving.

A vehicle includes a chassis, a first actuator coupled to the chassis, a second actuator coupled to the chassis, a third actuator coupled to the chassis, a fourth actuator coupled to the chassis, and a fluid circuit. The fluid circuit is configured to facilitate selectively fluidly coupling the first actuator, the second actuator, the third actuator, and the fourth actuator in a plurality of different configuration. In each of the plurality of different configurations, two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly coupled together while the other two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly decoupled.

A chassis for a lift device includes a base, an arm coupled to the base and configured to support a tractive element, and a plate extending from the arm at an upward angle. The arm includes a steering actuator interface configured to support an end of a steering actuator for the tractive element. The plate is configured to extend past the steering actuator.

A machine includes a chassis, a turntable coupled to the chassis, a boom coupled to the turntable, an axle, a first actuator, and a second actuator. The chassis has a first end and an opposing second end, and defines a longitudinal center axis. The turntable is selectively rotatable about a rotation axis. The axle is pivotally coupled to the first end of the chassis and configured to pivot about the longitudinal center axis. The first actuator is coupled to the first end of the chassis and positioned on a first side of the longitudinal center axis. The first actuator is extendable to selectively engage a first contact point on the axle. The second actuator is coupled to the first end of the chassis and positioned on an opposing second side of the longitudinal center axis. The second actuator is extendable to selectively engage a second contact point on the axle.

A damping device includes a damper provided to an outer end of a stacker crane in a traveling direction. The damper includes: a rod member extending along the traveling direction; a first biasing member configured to bias the rod member outward in the traveling direction; and a movement restriction mechanism configured to allow inward movement of the rod member in the traveling direction and restrict outward movement of the rod member in the traveling direction when the rod member has moved inward in the traveling direction.

A stack operating vehicle for storage and retrieval storage units. One embodiment of the stack operating vehicle comprises a first bearing device with a first bearing base and a first holding device for handling at least one storage unit; a second bearing device with a second bearing base and a second holding device for handling at least one storage unit. The second holding device is movably supported by a guiding device along a horizontal direction; a vertical guide arrangement at which the first bearing base and the second bearing base are respectively guided on an adjustment path along the vertical direction which are formed such that the first bearing base and the second bearing base overlap one another over their entire adjustment paths in the vertical direction. The disclosure also relates to a method for execution of storage orders with storage units with such a stack operating vehicle.

An apparatus for lifting and transporting loads, in particular corresponding containers, preferably in the form of empty containers, including a support chassis, for resting and movement means of the apparatus with respect to the ground, in particular including means, or front wheels, for resting and movement and means, or rear wheels, for resting and movement, in particular said front and/or rear means, or wheels, for resting and movement having a respective transversal, or horizontal, rotation axis; lifting and lowering means of the load, including a respective mast, in particular extending upwards, and gripping means of the load, which gripping means are mobile along said mast; said mast of said lifting and lowering means of the load being positioned at or posteriorly of the respective rotation axis of the front means, or wheels, for resting and movement of the apparatus with respect to the ground.

A fork carriage for an industrial truck, which has a load-side main metal sheet, a fork-side main metal sheet and a driver-side main metal sheet, which are connected to a box-shaped fork carriage body with six flat sides, wherein the fork-side main metal sheet has two connecting interfaces for two fork prongs, the load-side main metal sheet has laterally two folded side plates, on each of which a kinematics interface is arranged, and the driver-side main metal sheet has a folded cover plate.
