A hanging device includes an accommodation main body, a sliding assembly, a hook, and the accommodation main body that includes two parallel sidewalls, in which a first vertical path is defined between the two sidewalls. The sliding assembly is movably connected between the two sidewalls to move relative to the main body along the first vertical path. The sliding assembly further includes a sliding rail which defines a second vertical path, and the hook is movably connected to the sliding rail to move relative to the sliding assembly along the second vertical path.

A transport vehicle includes a base, wheels connected to the base, and load receiving elements. At least two of the wheels have a track width therebetween in each of a transverse drive and in a longitudinal drive. The track width in the longitudinal drive and the track width in the transverse drive are each variable. The transport vehicle is transports a load having a longitudinal direction and a transverse direction between the wheels. The transport vehicle is drivable both in the transverse drive and in the longitudinal drive.

The technology disclosed relates a lumber grabber for grasping timber. The lumber grabber can achieve grasping large packages of lumber of various work lengths. In one configuration, the lumber grabber includes moveable forks for grasping lumber movably supported by a frame, affixable to a crane. Forks positioned at ends of the frame and arranged to open and close relative to one other under power by a source of motive force; thereby enabling grasping and ungrasping of packages of lumber under programmed control of a programmable controller executing stored instructions.

A gripper device includes a holding portion that is attached to an elevating section capable of lifting and lowering above a transfer section to hold an article, a first positioning section that is attached to the elevating section and that positions the holding portion in a horizontal direction with respect to the article by contacting the article at two first contact positions in an upper portion of the article, and a second positioning section that is attached to the elevating section and that positions the holding portion in a height direction with respect to the article by contacting the article at three second contact positions that are not located on a straight line in the upper portion of the article.

The warehouse (1) for items in the form of raw materials or basic components, comprises: a plurality of item storage areas (10), at least one storage area (10), referred to as the upper area, being superposed with at least one storage area referred to as a lower storage area, each storage area (10) comprising a number of item storage locations (11) formed on the floor of said storage area (10), at least one carrier able to move items from an upper storage area (10) to a lower storage area (10), and vice versa, for each upper storage area, at least one manipulator robot (2) able to pick up an item from one of the storage locations (11) and transport it to a carrier, and vice versa, and for each lower storage area, at least one manipulator robot (2) able to pick up an item from one of the storage locations (11) and transport it to a workstation (T), and vice versa, and able to pick up an item from the carrier and transport it to one of the storage locations (11) or to a workstation (T), and vice versa.
Each manipulator robot (2) is able to move over a storage area (10) during the transporting of an item.

An object of the present disclosure is to provide a utility pole rotation apparatus and a position control method that can reduce not only the number of workers for adjusting an orientation of a scaffold bolt (an orientation of a side surface of the utility pole) but also the number of workers for stopping swinging of the utility pole, which cannot be simultaneously reduced in the related art.

The utility pole rotation apparatus according to the present disclosure includes a gripping portion that grips a utility pole, and a roller having a cylindrical shape that contacts the utility pole at an inner side of the gripping portion and rotates the utility pole with a longitudinal direction serving as an axis due to rotation of the roller.
