A transfer system and a transfer method are provided. The transfer system includes trolley member and a control device. The trolley member moves on a transport rail. The control device is configured to send a first control signal to the trolley member when the trolley member moves to a first preset site. The trolley member grabs a first-type carrier according to the first control signal. The control device is further configured to send a second control signal to the trolley member when the trolley member moves to a second preset site. The trolley member grabs a second-type carrier according to the second control signal. The first-type carrier is configured to carry a semiconductor material, and the second-type carrier is configured to carry a semiconductor material different from the semiconductor material carried by the first-type carrier.

A method and apparatus for enabling elevated trains for travel both above as well as below a vertically tiered pair of tracks by having wheels both in the upper and lower area of the train with the ability to switch, at the end of the line, from traveling on the upper tracks using lower wheels to traveling on the lower track using upper wheels. The method and apparatus of switching between upper and lower tracks enables trains to be moved between multiple levels serving as passing loops as well as vertical depots.

A sub-path is connected to a first main path and a second main path along which an article transport vehicle travels in a direction opposite to that of the first main path. The sub-path includes an intersection portion, a first upstream path connected to the first main path and the intersection portion, a second upstream path connected to the second main path and the intersection portion, a first downstream path connected to the intersection portion and the second main path, and a second downstream path connected to the intersection portion and the first main path. In the intersection portion, a first connection path that connects the first upstream path and the first downstream path, and a second connection path that connects the second upstream path and the second downstream path are provided so as to be located at the same height and to intersect each other.

A bolster beam is correspondingly connected to a connection base by means of a damping unit; the radial dimensions of an outer wall of an inner supporting member and an inner wall of an outer supporting member gradually decrease from one end to the other end in a vertical direction; one of the inner supporting member and the outer supporting member is connected to the connection base, and the other one is connected to the bolster beam; when in use, the inner supporting member and the outer supporting member tend to be close to each other, and since surfaces, close to each other, of the two are configured to be tapered, the two can-not be relatively separated; when getting closer to each other, the inner supporting member and the outer supporting member produce a compression action on an intermediate buffer member, and the intermediate buffer member is elastically deformable.

A method for operating a conveying system is provided. An overhead hoist transport (OHT) vehicle is provided, wherein the OHT vehicle includes a gripping member configured to grip and hold a carrier, and a receiver configured to receive a signal. The signal is transmitted to the receiver of the OHT vehicle. The OHT vehicle is moved toward the carrier, and the carrier is gripped by the gripping member of the OHT vehicle. A lifting force is determined based on a weight of a carrier, a number of workpieces in the carrier, or a vertical distance between the OHT vehicle and the carrier, and the lifting force is applied to the carrier.

A load-handling device is provided for lifting and moving containers stacked in stacks in a storage system. The load-handling device includes a body; a wheel assembly arranged to support the body; a container-lifting mechanism configured to lift a container into or out of the body; and a wheel-positioning mechanism with wheel-engaging functionality for selectively engaging either a first set of wheels of the wheel assembly with a first set of rails or tracks of the storage system, or a second set of wheels of the wheel assembly with a second set of rails or tracks of the storage system. A wheel-engaging device can include at least one non-vertically-orientated linear actuator and/or at least one eccentric-rotation-based wheel-engaging device.

A continuously moving cableway system for the transport of cars with passengers on board has two pairs of track cables, which extend between, two towers. Specially fitted open transport cabins, are moved along the track cables by at least one traction cable. Speed reducers located at ground level outside of the two towers. Access control, toll type, with rising arm barrier outside of the two towers. Security gates actioned by hydraulic jacks located at ground level outside of the two towers. Conveyor belts located at ground level between the two towers. Roller ramps, conveyor belt, security gates actioned by hydraulic jacks inside of the specially fitted open transport, cabins.
