A robotic picking assembly (100) comprising an arm support arrangement (8) configured to move vertically and to rotate about a vertical axis. A horizontally extendable arm (1) is supported in the arm support arrangement. A gripping tool (20) arranged at a free end (1a) of the arm. The arm comprises arm modules (2) linked together in a chain. The arm modules (2) have a pivot means (4) linking adjacent arm modules together in a pivoting manner and a pivot restriction means (15, 16, 18, 19) limiting curving of the arm to only one direction. The arm support arrangement (8) has an arm guiding arrangement (25, 21, 21a, 21b, 33) guiding the arm between an extended position and a retracted position, and an arm drive arrangement (7) configured to move the arm between said extended and retracted positions.

A handling device comprising an extending support, comprising a first projection element which is arranged on the support in a rotationally fixed and/or non-displaceable manner and extends in a first projection plane transversely to the support in a first projection direction, comprising a second projection element which is connected to the first projection element via a first joint so as to be pivotable in a second projection plane, comprising a third projection element which is connected to the second projection element via a second joint so as to be pivotable in a third projection plane, wherein, along the support axis, the first projection plane overlies the second projection plane and the second projection plane overlies the third projection plane, wherein the second projection element can be pivoted under the first projection element and the third projection element can be pivoted under the second projection element and the first projection element.

A system for handling pipes on a drilling rig includes an elevator suspended from a stand transfer vehicle, a top drive or other lifting device of a drilling rig. The system also includes a rig-floor pipe lifting machine including a fork sized to engage a tool-joint of a pipe. A navigation system includes a controller that can be programmed to autonomously drive the rig-floor pipe lifting machine.

A portable lifting arm includes a base, a plurality of casters fixed to a bottom side of the base, an arm mounting structure extending upward from a top side of the base, and an arm. The arm includes a first arm segment having a first end and a second end, the first end of the first arm segment being attached to the arm mounting structure, a second arm segment having a first end and second end, the first end of the second arm segment rotationally connected to the second end of the first arm segment, and a power tool rotationally connected to the second end of the second arm segment. A controller in electrical communication the power tool selects between predetermined settings on the power tool based on a position of the first arm segment and the second arm segment relative to the arm mounting structure.

A lift truck is configured to suspend a load above the ground and includes a self-propelled vehicle and a boom assembly. The vehicle defines an operator station to support an operator during lift truck use. The boom assembly includes a bifurcated, upright support frame attached relative to the vehicle and an elongated transverse boom. The transverse boom extends longitudinally to present a proximal mounting end and a distal lifting end configured to support the load in a space below the lifting end. The support frame includes a pair of upright supports that are attached relative to the mounting end to cooperatively support the transverse boom. The supports are laterally spaced apart to cooperatively define an upright support opening that permits an operator to view the load from the operator station by looking through the support opening along a longitudinal line of sight.

A system for moving a shelving system includes a lifting system that is operable to engage a section of a shelving system with a lifting element and to move the section of the shelving system upwardly or downwardly relative to a ground surface. The system also employs a moving device that is positionable between the shelving-system section and the ground surface when the lifting device moves the shelving-system section upwardly. The moving device also receives the section of shelving system onto a receiving area when the lifting device lowers the shelving-system section. The at least one movement component allows the at least one moving element to move relative to the ground surface. A lifting system for lifting a shelving system may include a jack and a lifting bracket that couples operation of the jack to upward or downward movement of the shelving-system section.

A robot-enabled method of picking cases in a warehouse is provided. A robotic vehicle includes a load platform and a robotic order selector, and has access to an electronically stored representation of a warehouse. The representation includes a map that defines aisles for storing items arranged as pick faces within the warehouse. A pick list is generated from an order; the pick list provides identifications of items to be picked to fulfill the order. A plurality of stops at pick faces associated with the items is determined. A route within the map is generated that includes the plurality of stops. The robotic vehicle iteratively guides itself along the route and automatically stops at each of the plurality of stops to enable robotic loading of at least some of the items from the pick list onto the load platform.

An aerial work platform and a floating control system thereof, the system comprising a driving mechanism, a hydraulic oil tank, a hydraulic pump, a floating control valve, a floating mechanism, a boom function valve, an actuator, and an accumulator: the floating control valve comprises a first one-way valve, a second one-way valve, a pressure reducing valve, and a logic valve; and an oil inlet of the first one-way valve serves as the oil inlet of the floating control valve, an oil outlet of the first one-way valve is connected to a pipeline connecting the accumulator, the pressure reducing valve and the logic valve, the logic valve is connected to the second one-way valve, an oil outlet of the second one-way valve serves as the feedback oil port of the floating control valve, when the hydraulic pump is a variable displacement pump, a feedback oil port of the floating control valve and a feedback oil port of the boom function valve are connected to a feedback oil port of the variable displacement pump; when the hydraulic pump is a fixed displacement pump, a feedback oil port of the floating control valve is connected to a feedback oil port of the boom function valve. The invention can reduce the power loss and improve the reliability of the system.

A driverless automatically guided transport vehicle for conveying payloads, for example a material transport vehicle in a factory, having a payload lifting apparatus. In order to offer a transport vehicle which is improved with regard to the securing of loads, it is proposed that the transport vehicle has a retaining apparatus for securing the load on the transport vehicle, the activation of which retaining apparatus is positively coupled to the lifting movement of the lifting apparatus.
