A common connection apparatus for coupling a power tool to an extensible arm and a power supply, the apparatus including a tool support base designed to support a tool, and a power supply support base designed to be affixed to the end of the extensible arm. The tool support base and the power supply support base each include a plurality of power connectors, positioned for engagement when the bases are aligned. The tool support base also has an alignment stab, which is received within a channel of the power supply support base. A plurality of pins are further positioned on the tool support base, to be received in apertures of the power supply support base. By this configuration, the bases may be aligned and engaged, facilitating the transmission of power from the machinery to which the arm is affixed, to the tool.

A container retrieval apparatus includes: a warehouse arranged inside a body and provided with a goods inlet; an extendable device having extendable arms arranged on two opposite sides of the goods inlet, each extendable arm having at least three arms capable of sliding relatively and extending in a first direction corresponding to a goods inlet and outlet direction of the warehouse, first arm sections of the arms are slidably connected to the body, and tail ends of tail arm sections that are away from the body are provided with shifting finger structures; a driving device including a driving assembly for driving the first arm sections to slide relative to the body, and a linkage mechanism for driving linkage between adjacent arms in each extendable arm; and a control device which controls the shifting finger structure to rotate to a position where a container to be carried can be shifted.

An industrial truck comprises a lift frame having a load part for carrying a load and a hydraulic system including at least one hydraulic cylinder having a piston rod disposed within a cylindrical housing, and a hydraulic power unit. At least one sensor is configured to determine at least one of: (i) an actual speed of the piston rod of the at least one hydraulic cylinder, and (ii) an actual acceleration of the piston rod of the at least one hydraulic cylinder. Furthermore, a control unit is configured to: (i) receive at least one of a target speed of the piston rod and a target acceleration of the piston rod, (ii) determine at least one of a speed control deviation value from the target speed, and an acceleration control deviation value from the target acceleration, and, (iii) regulate at least one of the actual speed of the piston rod based on the actual speed control deviation value and the actual acceleration of the piston rod based on the actual acceleration control deviation value.

A lifting device for an industrial truck comprises a lift frame with a moveably guided load carrier and at least one moveably guided mast stage. A free lift cylinder is configured to actuate the load carrier and at least one mast lift cylinder is configured to actuate the at least one mast stage. A hydraulic assembly supplies the free lift cylinder and the at least one mast lift cylinder with hydraulic fluid and further comprises at least one delivery valve and at least one recirculating valve.

The present invention relates to an order picker with a wiring mechanism, belonging to the technical field of manned elevation equipment. The order picker with a wiring mechanism comprises a stationary part, an elevation mechanism and an elevation part, wherein the wire suitable for transmitting signals is connected between the stationary part and the elevation part. It also comprises a wire accumulator which acts on the wire in such a way that the wire is always tensioned between the stationary part and the elevation part; when the elevation part is raised, the wire accumulator starts to pay out the wire, and when the elevation part is lowered, the wire accumulator starts to stow the wire. The present invention adopts a wire accumulator structure which can avoid the wires which come from the chassis being nipped during elevation of the elevation structure.

A container retrieval apparatus includes a body, an extendable device, a control device, and a driving device. A warehouse is arranged inside the body, and the warehouse is provided with a goods inlet. The extendable device includes extendable arms arranged on two opposite sides of the goods inlet. Each extendable arm includes at least three arms capable of sliding relatively and extending in a first direction. First arm sections of the at least three arms are slidably connected to the body, and the tail ends of tail arm sections are provided with shifting finger structures. The driving device includes a driving assembly for driving the first arm section in each extendable arm to slide relative to the body, and a linkage mechanism for driving linkage between adjacent arms in each extendable arm. The control device controls the shifting finger structures to rotate to shift a container to be carried.

A conveyance apparatus (carriage main part) includes a link mechanism that advances and retreats a holding unit horizontally with respect to a link mechanism support unit, and includes a pair of multi-joint arms that connects the link mechanism support unit and the holding unit. The cable is fixed to the link mechanism support unit by extending from a portion thereof fixed to the holding unit in a retreating direction of an advancing and retreating direction, and then, being bent back in an advancing direction, and as the holding unit advances, the bent-back position F of the cable also advances.

Described is self-propelled working machine (1) provided with organ (10) for moving a load and equipped with a safety system designed to prevent a risk of instability and comprising means (3) for detecting a position and a weight of the load and further comprising a processing unit (2) connected to said detection means (3) and in turn comprising: a checking module (21) configured for comparing the weight of the load with a reference value, selected on the basis of a position of the load; and a limiting module (22) configured for producing a limiting signal suitable for limiting the movement of the movement organ (10), following the comparison performed by the checking module. The reference value is independent of an angular position of the movement organ (10).
