The article transport vehicle includes a travel section, a holding section, an elevating device, an inclination detection device, an inclination adjustment device, and an inclination control device for controlling the inclination adjustment device. The inclination adjustment device is configured to act on a target belt among a plurality of suspension belts to adjust an inclination of the holding section by adjusting a suspension height at which the holding section is held by the target belt. During the lowering of the holding section to the transfer position by the elevating device, the inclination control device executes an adjustment operation during lowering, in which the inclination of the holding section is detected by the inclination detection device, and based on the result of the detection performed by the inclination detection device, the inclination adjustment device is controlled to adjust the inclination of the holding section.

A trolley installer for use with a crane bridge is configured for supporting a trolley thereon. The trolley installer includes a lift system adapted for mounting to the crane bridge. The lift system includes a lift mechanism and a strand coupled to the lift mechanism. The trolley installer also includes a platform member including a table for supporting a trolley and an attachment mechanism for releasably coupling with the strand of the lift system. The lift mechanism is operable to lift and lower the platform member relative to the crane bridge.

A ceiling conveyance vehicle includes a traveling wheel to roll on a track including a first track and a second track and a main body below the track and coupled to the traveling wheel. The ceiling conveyance vehicle includes a direction changer to change between a first state in which the traveling wheel rolls on the first track and a second state in which the traveling wheel rolls on the second track, with an orientation of the main body with respect to the track maintained, an article holder capable of holding an article, a hoisting-and-lowering driver to hoist and lower the article holder, a lateral slider to slidingly move the hoisting-and-lowering driver in a horizontal, linear direction, and a first rotational driver to rotationally drive the lateral slider around a first perpendicular axis with respect to the main body.

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 trolley of a rope crane, comprising a trolley body, a transverse load beam of the trolley, a hoisting mechanism and comprises a rope drum, a hoisting motor for driving the rope drum, and a gear for coupling the hoisting motor to the rope drum, whereby the gear has a primary side and a secondary side, and whereby the rope drum is located, in the vertical direction of the trolley, between the hoisting motor and load beam parallel to the load beam. The hoisting mechanism is supported by a three-point support to a main beam, whereby the first support point and second support point are adjacent to the secondary side of a gear, and whereby the third support point is formed by a support of the rope from end facing away from the gear to the load beam at a lateral distance from the first and second support point.

The hoisting mechanism is supported by a three-point support to a main beam, whereby the first support point and second support point are adjacent to the secondary side of a gear, and whereby the third support point is formed by a support of the rope from end facing away from the gear to the load beam at a lateral distance from the first and second support point.

A self-maintaining crane system including a bridge, a trolley, a hoist, and sensors for use within a hostile environment, such as a wastewater treatment facility, is presented. The bridge is movable along a pair of runway rails within the hostile environment. The trolley is movable between the runway rails. The hoist with extendable-retractable cable is movable with the trolley. Bridge sensors separately determine whether the bridge has engaged a bridge home position and a bridge end position. The bridge is movable away from the bridge home position and back toward the bridge end position. Trolley sensors separately determine whether the trolley has engaged a trolley home position and a trolley end position. The trolley is movable away from the trolley home position and back toward the trolley end position. Hoist sensors separately determine whether the cable has engaged a hoist home position and a hoist end position. The cable is extendable away from the hoist home position and retractable toward the hoist end position. Sensors facilitate automated movement of bridge, trolley, and cable so as to minimize functional impairment of the crane system by the hostile environment.
