An assistive robot system includes a lifting mechanism, a movable arm assembly, a processing device, and a non-transitory, processor-readable storage medium in communication with the processing device. The processing device transmits a command to the lifting mechanism to cause the lifting mechanism to move the movable arm assembly such that a container is gripped within the movable arm assembly, transmits a first one or more signals to the movable arm assembly to cause the movable arm assembly to extend in a system longitudinal direction such that the movable arm assembly grips the container. The movable arm assembly is positioned at a release location and transmits a second one or more signals to the movable arm assembly to cause the movable arm assembly to extend in a system lateral direction such that the container gripped within the movable arm assembly is released from the movable arm assembly at the release location.

The present application provides a movement buffering control system and method for forklift tilt cylinder based on angle compensation in the field of forklift control, which includes a tilt cylinder configured to control forward and backward tilting of a mast of a forklift and a lift cylinder configured to control the lifting of a fork, and further includes a controller, wherein a signal input terminal of the controller is connected to a first angle sensor to measure a tilt angle of the mast relative to a vertical plane, a second angle sensor to measure a tilt angle of a vehicle body relative to a level ground, and a pressure sensor, and wherein a signal output terminal of the controller is connected to a display, a forward-tilting proportional valve to control the oil for forward-tilting of the tilt cylinder.

Extendable mast systems and methods for a material handling vehicle include a base mast having a first web connecting a first web first flange and a first web second flange; a base mast bearing; a base mast bumper; a vertically extendable mast having a second web connecting a second web first flange and a second web second flange; and a vertically extendable mast bearing. The base mast bearing is spaced apart from the second web first flange defining a base mast bearing space between the base mast bearing and the second web first flange. The vertically extendable mast bearing is spaced apart from the first web first flange defining a vertically extendable mast bearing space between the vertically extendable mast bearing and the first web first flange. And the base mast bumper maintains the base mast bearing space between the base mast bearing and the second web first flange.

A vehicle-mounted device includes an analysis unit and a control unit. The analysis unit detects an insertion target into which an insertion blade can be inserted, on the basis of sensing information acquired from a spatial recognition device. The control unit performs a loading misalignment determination to determine whether or not the insertion target loaded on a conveyance destination is misaligned from the conveyance destination on the basis of the sensing information.

The invention relates to an industrial truck comprising

a chassis (6),
a mast (8) arranged on the chassis (6) in an upright position, a load-carrying apparatus (36), which has at least one load-receiving means (42) for receiving a load that is to be transported,
a support structure (9) that supports the load-carrying apparatus (36) on the mast (8) and can be moved, together with the load-carrying apparatus (36), upwards and downwards on the mast (8), and comprising
a device (54) for reducing vibrations,
wherein the device (54) for reducing vibrations has at least one additional mass body (60), which is supported by the mast (8) or the components connected thereto and is not constantly rigidly coupled to the mast (8) or the support structure (9) or the load-carrying apparatus (36), but is movably mounted by means of a bearing arrangement (62) such that it is movable relative to the mast (8) in response to mast vibrations, in particular to mast vibrations having horizontal vibration components, in order to counteract mast vibrations.

An industrial truck (2) with a lift mast (4), a hydraulic system (10), and a method for operating a hydraulic system (10). The lift mast (4) of the industrial truck (2) is driven by a mast lift cylinder (12) and includes at least one mast lift stage (42). A free lift stage is present that is driven by a free lift cylinder (8) with which a load receiving means (6) can be displaced along the lift mast (4). The industrial truck (2) includes a hydraulic system (10) for supplying the at least one mast lift cylinder (12) and the at least one free lift cylinder (8) with a hydraulic fluid (14). The hydraulic system (10) is configured to at least at times simultaneously actuate the at least one mast lift cylinder (12) and the at least one free lift cylinder (8) in load lifting operation and/or in load lowering operation.

A method for retrieving an inventory item based on a handling robot, where the handling robot includes: a storage frame; and a material handling device installed on the storage frame, and including a telescopic arm and a manipulator installed to the telescopic arm; and the method for retrieving an inventory item includes: driving, by the telescopic arm, the manipulator to extend to a preset position of warehouse shelf along a preset horizontal reference line; loading, by the manipulator that is remained on the reference line, the inventory item located in the preset position; driving, by the telescopic arm, the manipulator loaded with the inventory item to move to the storage frame along the reference line; and unloading, by the manipulator that is remained on the reference line, the inventory item to the storage frame.

A lift arrangement of a lift truck, especially a forklift truck, has a lift mast defining a z-axis. The lift mast includes a first mast section and a second mast section. Damping elements made from elastic material are provided on the first mast section and/or the second mast section preventing a hard impact of the second mast section with the first mast section at the run-in end position of the second mast section. The damping elements are configured and arranged in such a manner that, in addition to damping the movement of the second mast section in the direction of the z-axis, the damping elements damp movements of the second mast section in the directions of the x-axis and the y-axis running perpendicularly to the z-axis.
