Proposed are an OHT vehicle and a method of controlling the operation of the same. More particularly, proposed is a technology in which when a hand unit of an OHT vehicle loads a transfer container and unloads the same to a destination load port, an error between a recess of the transfer container and a positioning pin of the load port caused by the tilt of the transfer container is resolved through position correction of the hand unit, thereby enabling the transfer container to be accurately placed on the load port.

A gripping and carrying device for moving a container having a longitudinal axis and a transversal axis where in the device comprises a substantially L-shaped frame extending along the longitudinal axis and connected onto a mobile crane, the frame having a distal end provided with at least one hooking device configured to engage onto at least one complementary hooking device provided on the container and a proximal end provided with a grabbing and gripping deck having grab handles rotationally mounted onto the deck and a gripping device translationally mounted onto the deck, mobile between a releasing position wherein the gripping device are disengaged from the container and a gripping position wherein the gripping device are configured to engage into the container.

A component-handling device for handling components to be coated comprises a grasping element capable of having at least one of its volume and its shape changed to grasp a component, whereby the component can be handled. A method for handling components to be coated comprises changing at least one of a volume and a shape of the grasping element to grasp a component, thereby handling the component.

A lifting apparatus for lifting a tank car is provided. The lifting apparatus can include a first arm to surround and not contact a tank car jacket and a second arm to surround and not contact the tank car jacket.

A mechanical hand is provided that can increase the operation stroke and also the gripping force of a pair of gripping members. The hand includes first and second sliders, a driving source, a rotating plate, a first clamping link. Of these components, the first and second sliders are provided on a hand body so as to be linearly movable in opening and closing directions and the driving source is provided in the hand body. The rotating plate is rotatably driven by the driving source. The first clamping link is linked with the rotating plate so as to be only rotatable on a first shaft, and is linked with the first slider so as to be only rotatable on a second shaft. Moreover, the second clamping link is linked with the rotating plate so as to be only rotatable on a third shaft, and is linked with the second slider so as be only rotatable on a fourth shaft. The first and second sliders move linearly in the opening and closing directions by making the driving source rotate the rotating plate.

In a lifting clamp, a pair of opposite pieces are provided to a main body, wherein the opposite pieces are opposed to form a gripping space where an object to be transported can be gripped. Contact units to contact the object to be transported are provided on the respective gripping space sides of the opposite pieces. A handle is attached to the main body to be rotatable relative to a spindle that is disposed along a gripping direction shown by a dot-dashed line. A conversion unit that converts a rotational movement by turning of the handle into gripping movement to push the contact unit to the gripping side is disposed between the contact unitand the opposite piece. The contact unitis attached to a spindle that supports the handleon one side, and the size of the gripping space can be changed by sliding the spindle with respect to the opposite piece.

A hand intended for a humanoid robot comprises a palm and several fingers that are motorized relative to the palm. According to the invention, the hand comprises an actuator common to several fingers and a spreader making it possible to distribute a force exerted by the actuator toward the fingers.

A gripper device comprises a gripper with a gripper arm rotatable around a rotation axis such that the gripper is movable between an open end position and a closed end position, and a hoisting device connected to the gripper and comprising a first cable and a second cable which are each connected with their one outer end to the gripper and are each connected with their other outer end to respectively a first and second hoisting means for raising and lowering the gripper with the cables, wherein each hoisting means is, driven by a separate drive, wherein a controller transmits the same control signal to both drives for the purpose of raising or lowering the gripper, and each drive comprises a motor with internal slippage or a slippage coupling so that synchronous running of the hoisting means is automatically realized.
