A conveyance device (100) comprises: a carriage (10); a support column (20); a lifting device (30) that moves in the vertical direction along the support column (20); and a load platform (90) that is moved in the vertical direction by the lifting device (30). The lifting device (30) includes an upper guide (40), a lower guide (50), and a linking member (60) for linking an upper member (41) and a lower member (51) together. The upper guide (40) includes: a first wheel (42) that rolls on a rear surface (22) of the support column (20); and the upper member (41) which supports the first wheel (42). The lower guide (50) includes: a second wheel (52) that rolls on a front surface (21) of the support column (20); and the lower member (51) which supports the second wheel (52), the lower guide being disposed below the upper guide (40). The load platform (90) is disposed in front of the second wheel (52), and is linked to front side and rear side portions of the linking member (60).

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.

Embodiments are directed to an assistive robot system. The assistive robot system includes a lifting mechanism, a movable arm assembly coupled to the lifting mechanism, a container tilting arm assembly, a processing device communicatively coupled to the lifting mechanism and the movable arm assembly, and a non-transitory, processor-readable storage medium in communication with the processing device. The non-transitory, processor-readable storage medium causes the processing device to transmit a command to the lifting mechanism to cause the lifting mechanism to move the movable arm assembly such that the container tilting arm assembly makes contact with a container and transmits 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 container within the movable arm assembly is pivoted against the container tilting assembly to tilt the container within the movable arm assembly.

An industrial truck having at least one hydraulic mast lift cylinder, which is connected to a hydraulic block via a hydraulic arrangement that limits a lowering speed of the mast lift cylinder. The hydraulic arrangement is formed to limit the lowering speed in a load-dependent manner to at least two maximum values. A first maximum value is given for the lowering speed at the nominal load while a second maximum value is given for the lowering speed with a load that is smaller than the nominal load, i.e., wherein the first maximum value is less than the second maximum value.
