A stocker is disposed above a processing device and includes: a plurality of shelves provided in multiple stages in an up-down direction, to place articles thereon; and a crane to place an article on the shelves or take out an article placed on the shelves. The shelves include: a carry-in/out port used for an overhead transport vehicle to place an article thereon; and storage shelves used for the crane to place an article thereon. The carry-in/out port has a vertical dimension that allows a grip of the overhead transport vehicle to place the article from above. More storage shelves are provided than the carry-in/out port and are provided to have a smaller vertical dimension than that of the carry-in/out port. The crane places an article on the carry-in/out port onto the storage shelves or place an article on the storage shelves onto the carry-in/out port by a transfer device.

A gantry system has at least one crane assembly, at least one support post, and at least one hoist. The crane assembly has a stationary base, a rotating base, and a crane arm. The rotating base is attached to both the stationary base and the crane arm in such a ways as to allow the rotating base and the crane arm to rotate while the stationary base remains stationary. The crane arm is supported on its far end by a support post. The crane assembly is configured such that the support post rests on an in-place girder. A hoist is attached and can move along the crane arm to position a railway component, such as a replacement girder and/or a precast panel.

The assembled-type traveling carriage includes: the telescopic cylindrical body being an extendable telescopic cylindrical body rotatably provided with a first screw at each end thereof, and incorporating an actuator configured to extend and withdraw a nest; a joint block provided with a second screw; a traveler rotatably provided with the first screw and attached a driving device thereto; and a coupling rod rotatably provided with the first screw on each end thereof. A first planar frame body is assembled by screwing joint blocks to four of the telescopic cylindrical bodies, screwing the travelers to the joint blocks such that the travelers are positioned on extension lines of the telescopic cylindrical bodies, and coupling one ends of the four telescopic cylindrical bodies to one another by the coupling rods through the joint blocks.

A method and apparatus for positioning robots using a gantry. A base platform is provided, and a work platform is positioned above the base platform for supporting one or more humans. One or more robots are supported on the base platform independently of the work platform. At least one gantry is positioned above the base platform and adjacent the work platform for supporting and positioning the robots along the work platform.

Gantry crane vehicle for performing one or more tasks in a photovoltaic array and method thereof. The gantry crane vehicle includes one or more base plates, and one or more tracks above the one or more base plates. Additionally, the vehicle includes one or more gantry assemblies configured to slide along the one or more tracks, and one or more first support trusses configured to support the one or more tracks above the one or more base plates. Moreover, the vehicle includes one or more second support trusses connected to at least some of the one or more first support trusses, and one or more storage cabinets located on the one or more base plates. The one or more storage cabinets include one or more top surfaces and one or more side surfaces, and the one or more top surfaces are located below the one or more tracks.

A deck hoist tractor (DHT) for an unmanned platform (1) comprising an elongated base frame structure (12) carrying respective caterpillar drives (18) on each side enabling the tractor (2) to move forward and rearward, characterised in that the tractor (2) further comprising a tower frame structure (10) extending in substantially vertical direction from one end section of the base frame structure (12), which tower frame structure (10) is carrying a cantilevered top frame structure (11) carrying a lifting apparatus (22, 21), said caterpillar drives (18) are located at the same end section as said top frame structure (11), that said base frame structure (12) is extended by respective cantilevered beams (12a) space apart with an opening between them, each cantilevered beam (12) having an adjustable support structure (19) adjacent to their distal end (12b) from the caterpillar drive (18), said cantilevered top frame structure (11) is extended to vertically correspond with said respective cantilevered beams (12a), and said lifting apparatus (20, 21) is arranged to be shifted both forward and rearward, in addition to laterally in said top frame structure in order to position a load supported in the lifting apparatus. The invention also relates to a temporarily installed escape chute (54) and a method for installing and removing a tote tank (70) on the platform (1).

A modular portable cask transfer (MPCT) facility is capable of transferring a canister containing spent nuclear fuel materials from or to a transportation cask respectively to or from a storage overpack. A transfer cask is utilized for the transfer. Telescoping legs enable movement of the transfer cask independent of the canister, which is moved using a hoist. Due to its modular configuration, the MPCT facility can be assembled, disassembled, and moved from one nuclear power plant to another.

An embodiment is directed to a slider and method for moving a hoist on a crane. The slider includes a hoist support member and mounting arms. The mounting arms extend from either end of the support member. A portion of each mounting arm is spaced from the support member to form a flange receiving slot which is dimensioned to receive a flange a beam of the crane. The slider is provided with a resilient member to resiliently maintain the slider in a position in which the slider is movable relative to a beam of the crane when no load is applied to the slider. The resilient member is compressed when a load is applied to the slider to allow the slider to frictionally engage the beam to prevent the slider from continued movement relative to the beam.
