Aspects of the present disclosure are directed toward apparatuses, systems, and methods for releasably connecting a first beam to a second beam. The apparatuses, systems, and methods may include a locking pin arranged on the first beam and configured to actuate between an unlocked position and a locked position and an arm coupled to the locking pin and extending parallel therewith. The apparatuses, systems, and methods may also include a sleeve arranged on the second beam and configured to receive the locking pin in the locked position to releasably secure the first beam to the second beam.

A plant building (4) includes a building body (5) that has a first installation region (51) where a first rotary machine (2) is installed, a second installation region (52) where a second rotary machine (3) is installed, and a carrying in and out region (53) provided between the first installation region (51) and the second installation region (52) in a horizontal direction, a first overhead crane (6) that is disposed in the building body (5) and is capable of traveling above the first installation region (51) and above the carrying in and out region (53), and a second overhead crane (7) that is disposed at a height position different from a height position of the first overhead crane (6) in the building body (5) and is capable of traveling above the second installation region (52) and above the carrying in and out region (53).

A crane may comprise a mast that includes a base end and a top end located opposite the base end, at least one support beam fixedly coupled to the mast adjacent the top end of the mast, a first runway beam fixedly coupled to the at least one support beam, and a second runway beam spaced from the first runway beam. In some embodiments, the first runway beam defines a first end and a second end, and the mast is located closer to the first end than the second end. The crane may also comprise a bridge movably coupled to the first runway beam and the second runway beam, a trolley movably coupled to the bridge, and a hoist coupled to the trolley. In some embodiments, the crane only comprises one mast.

A system and method for construction of a framed structure which permits on-site storage and relocation of construction materials using trolleys and cranes supported by the framed structure. The system provides a runway surface for removable attachment of trolleys, crane bridges, and platforms by offsetting the first longitudinal beam and a second longitudinal beam from a cross beam and where the first longitudinal beam, second longitudinal beam, and cross beam of the system provide components for the framed structure.

A transfer system for spent fuel canisters includes a carrier, a shielded bell trolley movable along the carrier and carrying a shielded bell, and a canister trolley movable along the carrier and carrying a lifting mechanism for raising and lowering the spent fuel canister into and out of the shielded bell. The canister trolley can move along the carrier independent of the shielded bell trolley and the shielded bell trolley can move along the carrier independent of the canister trolley. The shielded bell trolley and the canister trolley can be selectively interlocked for selected transfer operations.
