The second battery unit (134) may have various known structures capable of driving the second motor unit (133) by a remote signal.

[0048] A lower hanger (200) is fixed to the lower side of the remote hanger (100) as described above, on the lower side of the utility pole (10).

[0049] The lower hanger (200) is fixed to the lower part of the utility pole (10). The lower hanger (200) may have various known structures that can be fixed to the lower part of the utility pole (10).

[0050] The safety rope (300) is connected between the remote hanger (100) and the lower hanger (200). A locking device (400) is supported on the safety rope (300). The safety rope (300) may have various known structures.

[0051] The locking device (400) is movable in the up and down direction along the safety rope (300) in the extension direction of the utility pole (10) and is optionally fixed to the safety rope (300).

[0052] FIG. 7 is a drawing showing a locking device included in a remote hanger for utility pole work according to one embodiment.

[0053] Referring to FIG. 7, the locking device (400) includes a main body (410) through which the safety rope (300) passes, a locking part (420) that rotates inside the main body (410) to selectively secure the safety rope (300) to the main body (410), and a fastening hole (430) to which the worker's lanyard (20) is fastened. As an example, the locking device (400) shown in FIG. 7 may have various known structures that are movable along the safety rope (300) and selectively secured to the safety rope (300).

[0054] FIG. 8 is a drawing showing the installation of a remote hanger included in a remote hanger for utility pole work according to one embodiment on a utility pole. FIG. 9 is a drawing showing the remote control part of the remote hanger included in a remote hanger for utility pole work according to one embodiment adjusting the distance between a first fixed part and a second fixed part.

[0055] Referring to FIGS. 8, FIGS. 9, FIGS. 1, and FIGS. 2, as an example of installing a remote hanger (100) on a utility pole (10), a worker connects a safety rope (300) to a locking device (400) that can be used for rock climbing, etc. Subsequently, a lanyard (20) including a carabiner is connected to the locking device (400) to prevent the worker from falling. The worker connects the safety rope (300) to the remote hanger (100) from the ground.

[0056] Then, the worker uses a dedicated stick (30) to grasp the remote hanger (100) and inserts the first footrest bolt (11) on the upper part of the utility pole (10) into the through hole (112) of the first fixing part (110) of the remote hanger (100). Here, the dedicated stick (30) may have a structure capable of grasping the remote hanger (100).

[0057] The operator operates the remote control unit (130) of the remote hanger (100) using a remote signal transmitting device such as a remote control on the ground to bring the first fixing unit (110) and the second fixing unit (120) of the remote hanger (100) as close as possible to the circumference of the utility pole (10). As the second motor unit (133) of the remote control unit (130) loosens and tightens the bolt unit (131) against the nut unit (132), the gap between the first fixing unit (110) and the second fixing unit (120) is adjusted, so that the first fixing unit (110) and the second fixing unit (120) can be universally fixed to the utility pole (10) regardless of the size and position of the utility pole (10).

[0058] The operator can use a remote signal transmitting device, such as a remote control, on the ground to rotate the rotating part (121) of the second fixed part (120) so that the remote hanger (100) does not detach from the utility pole (10).

[0059] The worker installs a lower hanger (200) at the bottom of the utility pole (10) and connects a safety rope (300), which is combined with a remote hanger (100) fixed at the top of the utility pole (10), to the lower hanger (200).

[0060] The worker connects the carabiner of the lanyard (20) to a locking device (400) supported by a safety rope (300) connected between the remote hanger (100) and the lower hanger (200).

[0061] The worker can perform work on the utility pole (10) by wearing a safety device, such as a swing-type safety harness, on a lanyard (20) connected to a locking device (400). Due to the locking device (400) supported by a safety rope (300) connected to a remote hanger (100), the worker does not fall even if they let go of both hands from the pole, and the worker can descend from the pole to the ground while releasing the locking device (400).

[0062] The removal of the remote hanger (1000) for utility pole work can be carried out in the reverse order of the installation described above.

[0063] In this way, the remote hanger (1000) for utility pole work according to one embodiment does not require additional processes such as double or triple lanyard fastening on the pole due to the ground installation of the safety rope (300).

[0064] In addition, the remote hanger (1000) for utility pole work according to one embodiment can prevent accidents caused by errors by simplifying the installation process.

[0065] In addition, the remote hanger (1000) for utility pole work according to one embodiment is connected to a safety rope (300) that connects the remote hanger (100) fixed to the upper part of the utility pole (10) and the lower hanger (200) fixed to the lower part of the utility pole (10) from the start of climbing, similar to rock climbing, by a lanyard (20), thereby preventing the worker from falling.

[0066] In addition, since the remote hanger (1000) for utility pole work according to one embodiment can be installed on the utility pole (10) by one person, the efficiency of the utility pole work is improved.

[0067] That is, a remote hanger (1000) for pole work is provided to minimize the risk of a worker falling during pole work.

[0068] Although embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims also fall within the scope of the present invention.
