Disclosed are various embodiments, aspects and features an oscillating track system that includes an oscillating track lock subsystem. The oscillating track system may include a track operable to rotate around a housing structure that is configured to receive an axle. While in operation, i.e. while the track is being rotated around the housing, the oscillating track system may be able to oscillate about the axle and, in doing so, incline or decline to accommodate undulating terrain. Advantageously, when stopped, the degree to which the oscillating track system has oscillated around the axle may be locked in place via an oscillating track lock subsystem comprised within the oscillating track system, thereby providing stability to the heavy equipment that includes the oscillating track system.

The present invention discloses a lifting mechanism mounted on a lifting device, wherein the lifting device includes a carrying unit. The lifting mechanism is disposed under the carrying unit, and comprises a driving assembly and a lifting assembly. The driving assembly includes an axle fixing part, a drive wheel and a power source, and the lifting assembly includes a screw nut and a screw rod. An upper end of the screw rod is fixedly connected to the carrying unit. When the lifting mechanism is traveling, each drive wheel is in contact with a base surface and moves the lifting device on the base surface; and when lifting, each drive wheel rotates on the base surface to drive the screw nut to rotate about a vertical axis relative to the carrying unit, to drive the screw rod to lift the carrying unit along the vertical direction.

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

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.

The invention relates to an industrial truck comprising a chassis (6), which is supported by at least two front wheels (2) and by at least one rear wheel (3) on the ground (4), a mast (8) for a load-carrying apparatus (36), which is arranged in an upright position thereon in a mast support region (54) of the chassis (6), wherein the front wheels (2) are rotatably arranged on wheel arms (50, 50) that protrude forwards from the mast support region (54) of the chassis (6), and means (62, 64; 162, 164; 262, 264) for suppressing and reducing vibrations, wherein at least one of the wheel arms (50, 50), preferably both wheel arms (50, 50), is/are split into at least two wheel arm portions (50a, 50b), which are mounted by means of a bearing arrangement (56; 156) so as to be able to perform movements relative to one another, wherein the means for suppressing or reducing vibrations are designed or operable to influence relative movements of the wheel arm portions (50a, 50b), in order to ensure that any impacts owing to unevenness of the ground during travel can only be passed on to the chassis (6) and the mast (8) by means of the wheel arms (50, 50) in a reduced, and absorbed and damped manner, and that any mast vibrations are damped.

The present invention discloses a multifunctional vehicle lifting, steering, moving and obstacle crossing device. The apparatus is composed of a rotating mechanism, a lifting mechanism, a running mechanism and a control mechanism, is mounted at a bottom of an automobile, can be conveniently folded at the bottom of the automobile when not used at ordinary times, and has characteristics of portability, flexibility, no space occupation and easy operation. The apparatus can realize functions of a vehicle, such as lifting, rotating, moving and the like, in a wired or wireless control manner, and effectively overcome defects that the vehicle cannot realize four-wheel off-ground, entire side movement and in-situ rotation or pass through a narrow road or stride across a wide ditch or cross a high and narrow obstacle, thereby completing relatively difficult tasks of the vehicle, such as parking, moving, turning-around and turning in a narrow space, crossing ditches etc.

A lift machine includes a base having a first end and a second end, a first assembly, and a second assembly. The first end has first and second pivot points defining a first lateral axis. The second end has third and fourth pivot points defining a second lateral axis. The first assembly is pivotably coupled to the first and second pivot points. The first assembly extends away from the base in a first direction such that first and second tractive elements are longitudinally offset from the first lateral axis and spaced from the first end of the base. The second assembly is pivotably coupled to the third and fourth pivot points. The second assembly extends away from the base in a second direction such that third and fourth tractive elements are longitudinally offset from the second lateral axis and spaced from the second end of the base.

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.
