A port storage and distribution system for facilitating the transfer and/or storage of international shipping containers between container ships and ground transport carriers wherein an overhead grid guide track structure is provide that permits overhead transfer units to selectively engage and convey containers as required between the various ships, carriers and storage area without requiring multiple transfers of containers between different handling equipment. The system provides for container scanning and is either fully automated or partially manually controlled.

Magnetic circuit that has (a) a source of magnetic flux which includes an electromagnet or one or more permanent magnets, (b) at least two oppositely polarisable pole extension bodies associated with the magnetic flux source, the bodies being disc, wheel, roller or similarly shaped with an outer circumferential surface and held rotatable about respective axes of rotation, and (c) a ferromagnetic counter body which is arranged to cooperate with the pole extension bodies such as to provide an external flux path for the magnetic flux when in magnetic proximity or contact with the circumferential surface of the pole extension bodies, which is characterised in that the magnetic flux source is held stationary relative to the rotatable pole extension bodies.

A patient hoist is provided on a trolley which tides along a track, with the hoist being powered by a conductor extending along the track. A contact carrier is loosely fit within the trolley, and it bears a contact which elastically biased against the track conductor, with die contact being in electrical communication with the hoist: The contact carrier is tree to laterally displace with respect to the trolley so that it (and its contact) follows the contour of the track, with the contact remaining in electrical communication with the track conductor.

The invention relates to an air flotation device following the motion trail of a lifting point at an overlength distance without being influenced by the disturbing force of an air tube, comprising an air flotation shaft, an air flotation sleeve and a guide track, wherein the air flotation sleeve is sleeved on the air flotation shaft and comprises a left air flotation sleeve and a right air flotation sleeve; the left air flotation sleeve is sleeved at the left side of the air flotation shaft, and the right air flotation sleeve is sleeved at the right side of the air flotation shaft; the middle of the air flotation shaft is provided with a lifting bed; the lifting bed is connected with a lifting rope; the lifting rope moves along with a motion member; a slide block is slidably arranged on the guide track and is fixedly connected with the left air flotation sleeve and the right air flotation sleeve; the slide block is connected with a main air tube; the main air tube is communicated with a left branched air tube and a right branched air tube; the left branched air tube is connected with the left air flotation sleeve, and the right branched air tube is connected with the right air flotation sleeve. The air flotation device effectively prevents the resistance influence generated by the air tube in the frictionless motion process of an air flotation assembly along with the motion member, has good reliability and follows the motion trail of the lifting point at the overlength distance without being influenced by the disturbing force of the air tube.

An overhead traveling and transporting system includes a transporting carriage traveling along a track. The carriage has a gripping mechanism to grip an object, a hoisting mechanism to move down the gripping mechanism to a load port for the object, and a sensor emitting a light beam within a pseudo plane surface and receiving a reflection thereof. The system also has: a device for monitoring an obstacle existing in an emission direction of the emitted light beam, based on the reflected light; and a selecting device for establishing one condition that the obstacle existing forward in the traveling direction is monitored if the transporting carriage is traveling and establishing another condition that the obstacle existing downward from the transporting carriage is monitored if the gripping mechanism is moved down, by selecting the direction of emission and/or selecting an area of monitoring by the monitoring device.

An ID tag describing control data on a stopped position for each station 10, movement required for a transfer, and the like is installed in front of the station 10. An overhead vehicle 8 reads the control data and uses it for stoppage and transfer. The overhead vehicle 8 need not store the stoppage or transfer control data for each station 10. Further, the control data can be changed without updating the storage in the overhead vehicle 8.

A device for the suspension of a rail, especially of a hollow-section rail which opens downward in a suspension crane, includes a carrying apparatus with a traction element which has two ends. One of the ends of the traction element may be fasten to the rail. To provide a rigid suspension of a rail in which horizontal forces, especially pulse-like horizontal forces, are extensively damped, the device includes a rubber-metal element connected between the carrying apparatus and the traction element with two substantially horizontal metal carriers arranged at a distance from one another. A rubber or elastic element is fastened to the inner surfaces of the metal carriers, which inner surfaces face one another. The carrying apparatus is fixedly connected with the lower metal carrier and the other end of the traction element is fixedly connected with the upper metal carrier.

The invention relates to a construction device for a cable-stayed bridge, in particular to a bridge floor crane for the cable-stayed bridge. The bridge floor crane for the cable-stayed bridge comprises two sets of main trusses arranged oppositely, a craning system arranged above the main trusses and a walking system arranged below the main trusses, wherein the walking system comprises a main track laid on a mounted steel beam and a walking device in sliding fit with the main track, and an upper layer and lower layer structure is adopted by the main trusses. The bridge floor crane for the cable-stayed bridge further comprises a supporting system arranged on the lower portions of the main trusses, a rear anchoring system arranged on the outer sides of the two sets of the main trusses, a balance weight device and a safety device, the balance weight device and the safety device are arranged at the rear ends of the main trusses, and the supporting system comprises a middle supporting device arranged in the middles of the main trusses and a temporary supporting device arranged at the front ends of the main trusses. Through the adoption of the technical scheme, the bridge floor crane for the cable-stayed bridge has the advantages of being proper in craning height, strong in bearing capacity, good in construction stability, high in construction efficiency and high in safety.
