A central traction device for a straddling monorail train includes a traction pin and a traction beam. A central sleeve is provided at the center of the traction beam, and the traction pin is mounted in the central sleeve. An inner cavity of the central sleeve has a corset-shaped structure having large diameters on an upper end and a lower end and a small diameter at a middle part, forming double tapered bevels, and a resilient rubber bush is provided between an inner wall of the central sleeve and the traction pin. The device has a simple and compact overall structure and facilitates connection and separation between the train body and the bogie; by providing the lift assembly, the traction device is fixedly connected to the frame, thus the traction device can be wholly lifted; and operation process and environment of raising and lowering the vehicle are improved.

A conveyor apparatus for conveying a moving body along a conveyance path, the conveyor apparatus comprising: a frame body to which a pair of roller members that rolls along the conveyance path are attached; a pair of guide rails on which the roller members travel; cables for connecting various devices; and a support member having a support surface to support the cables, wherein each of the guide rails comprises: a traveling portion on which the roller members travel, and a side wall portion extending from the traveling portion, wherein the side wall portion of one of the guide rails and the side wall portion of the other one of the guide rails are arranged separately from each other, and wherein the cables are housed in a space defined by the support surface and the respective side wall portions.

An overhead transport vehicle includes a holding unit adapted to be lifted and lowered and configured to hold an article; a lifting drive section configured to lift and lower the holding unit; a lateral transfer mechanism configured to move the lifting drive section laterally with respect to a body section; a monitoring sensor provided to the lifting drive section and configured to monitor an area below the lifting drive section and be able to change a monitoring range; and a controller configured to change the monitoring range of the monitoring sensor in accordance with information on tilt of the lifting drive section with respect to a horizontal plane.

A monorail vehicle includes a chassis supporting a vehicle body, that includes a passenger floor and at least one side wall, and an electrical motor supported by the chassis. A drive wheel is coupled to a rotor of the electric motor with a rotation axis of the drive wheel substantially coaxial with an axis of the rotor. Portions of the drive wheel and the electric motor are positioned on both sides of an imaginary plane extension of the passenger floor. The drive wheel and the electric motor are covered by a shell that is integral to one side of the vehicle body and which defines a space between the other side of the vehicle body.
