Abstract: The invention provides a stacker crane, configured to move on a single rail provided along one or more racks, includes: a first wheel that moves on the rail; a second wheel that moves on the rail, and that is disposed spaced apart from the first wheel in a fore-and-aft direction; a vehicle frame supported by the first wheel and the second wheel; first drive supported by the vehicle frame for driving the first wheel. The vehicle frame includes: a first support frame for supporting the first wheel and the first drive means; a second support frame for supporting the second wheel; and a connection frame that connects the first support frame and the second support frame.

Abstract: A transport system for transporting transport containers storing articles in a sealed condition is disclosed. Each transport container has a support portion formed on an upper portion thereof. When the transport container is moved with the support portion suspended, a receiving device supports the bottom of the transport container to lessen the load applied to the support portion. As a result, deformation of the transport container is restrained to maintained the sealed condition.

Abstract: The present invention is based on the critically important feature of providing a left-right parallel arranged linear motor-based conveying system in which the upper surfaces of the guide rails do double duty as providing the rolling surfaces for the wheel pairs, and also as being secondary (reaction) conductor surfaces for the linear motors, and the linear motors are spaced closely above the upper surfaces of the guide rails by a predetermined clearance.

Abstract: A conveyor system utilizing the linear motor, comprising a conveyor cart and a guide rail for movably supporting the conveyor cart. The guide rail includes primary coils, and the conveyor cart includes a flexible secondary conductor extending longitudinally of the cart so as to follow the guide rail. The primary coils comprise a station primary coil disposed at each loading and unloading station for stopping and starting the converyor cart, two primary coils adjacent opposite ends of the station primary coil for decelerating the conveyor cart that is to be stopped at the station by the station primary coil and for accelerating the conveyor cart having started from the station to a target running speed, and a plurality of intermediate accelerating primary coils disposed between two adjacent stations for accelerating the conveyor cart to maintain the latter at the target running speed.
