The invention relates to a transfer system for transferring an item with a transfer assembly for transferring an item to a transporting carriage in a transfer area and with a transporting carriage for receiving the item from the transfer assembly in the transfer area.

Methods and systems for wirelessly transmitting power and/or data.

A load-handling clamp mountable on a lift truck is capable of clamping a load between respective opposed clamp arms each capable of hydraulic movement selectively toward or away from each other. One of the clamp arms is preferably substantially incapable of movement toward the other clamp arm unless actuated independently of the other clamp arm. One of the clamp arms also preferably has a lesser maximum range of hydraulic movement than the other of the clamp arms and is hydraulically movable at a maximum hydraulic pressure greater than that of the other clamp arm.

Hydraulic valve circuitry adapted for hydraulic connection to a lift truck having a mast and at least one lift cylinder for alternately raising and lowering the mast. The hydraulic assembly is also adapted for hydraulic connection to an attachment to the lift truck, the attachment having opposed clamps actuated by respective clamp cylinders. The hydraulic assembly preferably comprises a valve circuit capable of causing the at least one lift cylinder to be an accumulator.

A spool-less system for deployment, recovery and manipulation of a traversable road covering track is provided. The system includes an arcuate guide member detachably coupled to a retaining means; the guide member and retaining means defining a volume for receiving a roll of traversable road covering; the guide member arranged to contact the roll along a first arcuate range and the retaining means configured to contact the roll along a second arcuate range; and wherein the guide member and retaining means are detachably coupleable having, a first position in which, the guide member and retaining means are separated at a first diameter whereby the roll of traversable road covering may be deployed or recovered when the host machine is in motion, and a second position in which, the guide member and retaining means are separated at a second diameter in which the roll of traversable road covering is retained.

Hydraulic valve circuitry adapted for automatic weight-responsive control of load-clamping members of a load-lifting system having a free lift mast. The load-lifting system generally includes one or more fluid power actuator for applying a gripping force to a load, at least one elongate, longitudinally-extensible fluid power lifting device having a free lift range of motion and at least one main lift range of motion, and manually operated load-clamping and load-lifting selector valves. The hydraulic valve circuitry provides, independently, weight-responsive control of the load-clamping members when lifting a load, full-time automatic weight-responsive force control of the load-clamping members without concurrent manual actuation of load-clamping or load-lifting selector valves, and equalization of sensed load weight so that the sensed load weight is substantially independent of the longitudinally-extensible position of the lifting device.

A system for managing a paper roll includes an IC tag for long distance that is a non-contact passive type mounted on each of a plurality of paper rolls; a transmitter that transmits a radio wave toward the plurality of paper rolls; a receiver that receives a response radio wave from each of the paper rolls for the transmitted radio wave; a control device including a tag position calculation unit that calculates a three-dimensional position of the IC tag which has emitted the response radio wave, based on information regarding the received response radio wave; and a storage unit that stores three-dimensional position information of each of the plurality of paper rolls from information regarding the calculated three-dimensional position and paper information, which is specific to each of the paper rolls, as linked information.

A hydraulic control circuit operable to selectively hydraulically link first and second hydraulic actuators and to bypass that hydraulic link.

A load-handling clamp mountable on a lift truck is capable of clamping a load between respective opposed clamp arms each capable of hydraulic movement selectively toward or away from each other. One of the clamp arms is preferably substantially incapable of movement toward the other clamp arm unless actuated independently of the other clamp arm. One of the clamp arms also preferably has a lesser maximum range of hydraulic movement than the other of the clamp arms and is hydraulically movable at a maximum hydraulic pressure greater than that of the other clamp arm.

According to an embodiment of the present invention, there is provided a hand lift device including: a frame portion including a vertical frame, a first sprocket installed on an upper end of the vertical frame, and a second sprocket installed on a lower end of the vertical frame; a chain installed to engage with the first sprocket and the second sprocket; a cargo loading unit which is connected with the chain and disposed to be liftable along the vertical frame to load cargo; a power transmission portion which provides a driving force to the chain so that the cargo loading unit is lifted up and down; a sensor portion which is installed in an area where the frame portion is formed to be positioned at an upper side in a range where the cargo loading unit is lifted up and down and includes a proximity sensor to sense the cargo loaded on the cargo loading unit; and a controller which controls lifting up and down of the cargo loading unit by adjusting the driving of the power transmission portion according to a sensing signal from the sensor portion.

According to the embodiment of the present invention, since the operator can automatically load the cargo by controlling through the cargo loading unit without manually loading the cargo, the hand lift device can operate faster than manual operation, load more cargo over the same time, and operate with a small number of persons, thereby reducing the cost.
