A main carriage 12 is movably supported by pulleys 11a and llb, and at one end of the main carriage 12,
It extends parallel to the main rope 10 via pulleys 13 and 14 supported by the front foot 9 and the base pillar 8, respectively, and guide pulleys 15a and 15b supported by the roots on the sides, and then goes around the sides thereof. One end of the pullback cable 16 is tied, and one end of the pullback cable 16 is wound around the first drum 3 of the power winch 1.

A pair of guide pulleys 17a and 17b are supported below the main carriage 12, and the dual guide pulleys 17
On a and 17b there is a pulley 18.1 supported by the base pillar 8.
A pulling cable 20 is passed through and supported through a cable 9, with one end wrapped around the second drum 4 and the other end wrapped around the third drum 5.

On the pulling cable 20 between the guide pulleys 17a and 17b,
A rosing block 21 as a subcarriage is supported. The rosing block 21 includes second and third rosing blocks.
As shown in the figure, a drum 22 is provided, and the drum 2
The towing rope 20 is wound around the drum 25, and the drum 25 rotates via gears 23 and 24 as the drum 22 rotates. A luggage rope 27 is wrapped around it.

Near the main carriage 12 on the main rope 10, a collector 29 having a guide pulley 28 provided at its lower part is movably supported. A lifting cable 31 having a support pulley 30 attached to its tip passes through the guide pulley 28, and pulleys 32, 33 and 34 supported by the base pillar 8 and the front pillar 9 are connected to the other end.

are tied together, and the other end of the lead-in cable 35 is attached to the support pulley 3.
0, and is wound around the fifth drum 7 via pulleys 36a, 36b, 37 supported by the roots and a pulley 38 supported by the base pillar 8.

Next, the operation of this conveying device configured as above will be explained. In addition, the drums 3, 4゜5.6.7 are as follows:
The winding direction of the rope is forward rotation, and the unwinding direction is reverse rotation.

First, in order to move the main carriage 12 and the losing block 21 to the front post 9 side on the main rope 10, the second and third drums 4 and 5 are reversed and the pulling rope 20 is moved at the same speed. While rewinding, the first drum 3 is rotated in the normal direction to wind up the pullback cable 16. At the same time, the fifth drum 7
While rewinding the retracting cable 35 by reversing the rotation, the fourth drum 6 is rotated in the forward direction to wind up the lifting cable 31. In this way, the main carriage 12 is moved in the direction of the front post 9, and the collector 29 is also pushed by the main carriage 12 and moved in the direction of the front post 9.

Next, in order to lower the rosing block 21 at a desired position, the second and third drums 4.5 are reversed and the tow rope 20 is reeled back at the same speed, while the fourth drum 6 is lowered. While rewinding the lifting cable 31 by rotating it in the reverse direction, the fifth drum 7 is rotated in the normal direction to wind up the pulling cable 35.

In order to send out the hanging rope 27 in the rosing block 21, the second or third drum 4, 5 unwinds one of the ropes while winding up the other, and moves the pulling rope 20.

By doing so, the drum 22 around which the tow rope 20 is wound rotates, and the rotation is transmitted to the drum 25 via the gears 23 and 24, and the hanging rope 27 is sent out. Note that this sending-out operation of the hanging rope 27 is performed by changing the unwinding speed of the towing rope 20 by one drum 4 or 5 to the other drum 5 or 4 when the above-mentioned lowering block 21 is lowered.
It is possible to do this at the same time by making the unwinding speed slower than the unwinding speed.

In this state, the worker holds the hook 26 at the tip of the hanging rope 27.
[Carry it to the place where the wood W has been felled and hook it with the hook 26.
The wood W that has been cut down is secured. The operator can carry this hook 26 on both sides of the pull line 35 by the length of the hanging load line 27 (at least 15 m),
It is possible to collect wood over a width of about 30 m without moving the collector 29 or the pulleys 36a and 36b.

After locking the wood W to the hook 26 as described above,
The pulling cable 20 is moved in the opposite direction to the above and the hanging cable 2 is
Wind up 7.

Thereafter, while the fifth drum 7 is reversely rotated to rewind the tow rope 35, the second and third drums 4.5 are rotated forward to wind up the tow rope 20 at the same speed, and the fourth drum 6 is By rotating normally and winding up the lifting cable 31, the rosing block 21 is raised with the wood W in a state of being lifted up. In addition, during this lifting work, the second or third drum 4
．． It is also possible to perform the winding operation of the hanging rope 27 at the same time by making the winding speed of the towing rope 20 by one of the drums 5 slower than the winding speed of the other drum.

In this way, the timber W suspended from the rosing block 21 is transported to the first and fourth drums while winding up the tow rope 20 by rotating the second and third drums 4 and 5 at the same speed. , by reversing the fifth drums 3, 6.7 and pulling back cables 16, respectively.
．． Lifting cable 31. By rewinding the pull cable 35,
The carriage 12 is moved in the direction of the base column 8 and transported to the base column 8 side. In this case, the collector 29 uses the inclination of the main rope 10 to follow the carriage 12 by itself.
