A hoisting device includes a first part movably connected to a running rail above it, and a second part suspended under the first part, and a hoist arranged between the first part and second part to lift and lower the second part. In addition, a scissors mechanism is arranged between the first part and second part to prevent the horizontal movement and twisting movement of the second part in relation to the first part. Such a hoisting device is advantageous, because the second part of the hoisting device may be lifted and lowered at the same time as the first part is moved without any notable swinging exerted on the second part.

An article transport vehicle of this disclosure includes a fall restricting device. A vehicle body of the article transport vehicle includes a first cover section, a second cover section, and a cover connecting section. The fall restricting device includes a pair of fall restricting members and a driving mechanism. The pair of fall restricting members each include a supported section, a pair of vertical extension sections, and a lower connecting section. The driving mechanism drives the pair of fall restricting members to move between a restricting position and a release position. At the restricting position, the pair of vertical extension sections overlap a stored article in a second direction view, and furthermore the lower connecting section overlaps the stored article in a vertical view. At the release position, the lower connecting section does not overlap the stored article in the vertical view.

A trolley of a crane is arranged to move along a main support structure of the crane. The trolley includes a support frame structure; bearing wheels which are fastened to the support frame structure and by means of which the trolley is arranged to move along the main support structure; and a hoisting mechanism that has a rope drum for a hoisting rope, a rope pulley arrangement through which the hoisting rope may be guided from the rope drum to a fixed fastening point on the trolley, and a hoisting member in cooperation with the hoisting rope for hoisting a load. The rope drum is supported to the support frame structure of the trolley so that the axle of the rope drum is parallel to the main support structure. The rope pulley arrangement is located, in the axial direction of the rope drum, at least partly outside one rope drum end which is on the side of said fastening point. The support frame structure is divided into two separate frame parts, whereby the first frame part supports the rope pulley arrangement and the rope drum end on the side thereof, and whereby the second frame part supports the opposite end of the rope drum. A pivoted joint is arranged between the first frame part and the second frame part, which allows the first and second frame part to move relative to each other around the vertical and horizontal axis and the longitudinal axis of the first and second frame part.

An overhead transport vehicle travels along a travel rail and conveys a FOUP including a removable lid in a suspended state. The overhead transport vehicle includes a holder to grip the FOUP with the lid oriented in a width direction crossing the traveling direction, a pair of frames provided at the front and the back in the traveling direction relative to the holder, and a first lid drop-preventing member provided so as to be pivotable along a horizontal plane about a pivot shaft in the vertical direction, between an advanced position in front of the lid and a retracted position at a position retracted from the front of the lid.

There is provided a method of installing spiral hangers about a messenger line installed between first and second utility poles with a cable being lashed to the messenger line with a lashing wire. The method includes attaching a first and second spiral hangers to the messenger line between first and second utility poles with the first spiral hanger disposed about the messenger line and the cable. The method includes removing the lashing wire from being around the messenger line and the cable adjacent the second spiral hanger. The method includes moving the second spiral hanger towards the second utility pole. The method includes attaching a successive spiral hanger to the messenger line between the spiral hangers and repeating the moving of the second spiral hanger and attaching another successive spiral hanger.

Rail-mounted lift systems, systems comprising the same, and kits of parts for retrofitting rail-mounted lift systems are disclosed. A lift system includes a rail having a carriage support channel formed therein, a carriage slidably disposed in the carriage support channel for relative movement to the rail, a lift unit coupled to the carriage, the lift unit having a motor that extends and retracts a lifting strap, and a locating system having a first component and a second component separate from the first component. One of the first and second components is a transmitter providing a code that corresponds to a predetermined location and the other is a receiver detecting the code when the first and second components are moved in proximity to one another due to movement of the carriage along the rail.

An assembly system for assembling a gas turbine engine including a support beam defining a horizontal plane for assembly of engine components along a horizontal axis substantially parallel with the support beam. A forward arm is supported on the support beam for supporting a forward portion of an engine component. An aft arm is supported on the support beam for supporting an aft portion of the engine component. An aft mounting ring is attachable to an aft end of an engine assembly. A forward mounting ring is attachable to a forward end of the engine assembly. A drive is mounted to the aft arm engageable to the aft mounting ring for rotating the engine assembly about the horizontal axis. A roller is supported on the forward arm and engageable to the forward mounting ring to support the first end of the engine assembly during rotation about the horizontal axis. A method is also disclosed.
