Further, the second slider has no engagement between the protrusion and the engaging portion, and the tip of the second slider moves up and down above the peripheral surface of the rotating body.

Then, the traveling body stopped at the hoisting position is slightly moved in the mountain side direction by winding the pull line.

At this time, the second slider slides against the applied restoring force due to the engagement relationship between the protrusion of the rotating rotating body and the engaging portion, and the rotating body is maintained while maintaining the engagement state between the protrusion and the engaging portion. By continuing the rotation of, the posture is changed to a downward position in which the engaging portion is located below the rotating body.

After that, when the traveling body is made to travel a little in the valley direction, that is, to the luggage-lifting position by unwinding the tow line, the second slider slides against the applied return force due to the engagement relationship between the protrusion and the engaging portion. , The tilting body rotates in the forward direction by the engaging projections.

As a result, the locking part of the rocker rides over the upper end of the lever,
After passing over the above, the tip end of the oscillating body descends due to the imparted turning property, and the upper end of the lever and the locking portion are brought into an engaging relationship.

The second slider, which rotates the tilting body in the forward direction, rotates in a direction in which the tip of the second slider rises due to the engagement relationship between the protrusion and the engaging portion as the rotating body continues to rotate, and the protrusion and the engaging portion. When the engagement with and is released, it is returned by the applied restoring force to return to the original posture, and therefore, the tilting body is rotated in the backward direction by the applied turning property and the rocking body is pulled back.

Therefore, the lever related to the engagement is rotated to push the operation piece.

At this time, the locking device is depressed and engaged with the lever to maintain the push state of the operation piece.

When the operation piece is pushed and the switch is turned on, the hydraulic pressure of the hydraulic pressure accumulator causes the first cylinder to act to clamp the support line by the clamp device, so that the traveling body stops at the lifting position.

Further, since the engaging claw is disengaged from the collar by the action of the second cylinder, the tip end of the unwound retraction line descends toward the ground.

When the luggage is lifted while the tip of the towline is stopped on the luggage and the towline is wound up, the first slider is pushed through the action device while the first slider is pushed out by the brim that is fitted into the pendulum immediately before the lifting is finished. The locking device is operated to release the push state of the operation piece.

When the hydraulic switch is turned off with the release of the push, the first cylinder and the second cylinder stop working,
The engaging claws that have returned to the collar are engaged to maintain the suspended state of the luggage, and the clamps of the support lines are released by the clamp device.

Then, the luggage is taken out while the traveling body is traveling to the luggage unloading position by winding the tow line, and when the luggage reaches the unloading position, the traveling body is made to travel a little in the valley direction, and the same operation as above is performed. One piece is pushed to turn on the switch, the supporting cylinder is clamped by the acting first cylinder through the clamp device, and the engaging claw is disengaged from the flange by the acting second cylinder, and the pulling rope is rewound to lower the load. .

In addition, when the tow line is wound after the luggage is unloaded, the action of the first cylinder and the second cylinder is released in the same manner as described above, and the traveling body can travel in the valley direction.

Then, pull the traveling body 21 stopped at the lifting position.
By winding 45, run a little toward the mountain side.

At this time, since the rotating body 71 is rotated clockwise in FIG. 9, the protrusion 72 and the engaging portion 75 are engaged with each other and the second slider 74 is retracted in the right direction in FIG. 9 while compressing the coil spring 77. At the same time, while maintaining the engagement relationship between the protrusion 72 and the engaging portion 75, when the engaging portion 75 is positioned on the lower peripheral surface of the rotating body 71 due to the continued rotation of the rotating body 71, the tip end of the second slider 74 is lowered. And the downward posture (as shown by the chain line in FIG. 9).

Further, when the second slider 74 is in the downward position, the lower swinging piece 79 pushes up the second slider 74 to move the rotating body 71.
The engaging portion 75 is pressed against the lower peripheral surface of the.

After that, the unwinding of the tow line 45 causes the traveling body 21 to travel a little in the valley direction, that is, to the position at which the luggage A is lifted.
Since the rotating body 71 is rotated counterclockwise in the drawing, the second slider 74 is retracted by the engagement between the protrusion 72 and the engaging portion 75.

As a result, the tilting body 57 rotates in the forward direction (clockwise in FIG. 9) due to the collision between the lower swing piece 79 and the fixed piece 83.

When the tilting body 57 rotates, the locking portion of the rocking body 60 is pushed out.
Since the 63 rides over the upper end of the lever 32, and after riding over the above, the fifth spring 62 pulls down the tip of the rocking body 60,
The upper end of the lever 32 and the locking portion 63 are engaged with each other.

The second slider 74 in which the tilting body 57 is rotated in the forward direction.
Is rotated in a direction in which the tip end is lifted (toward the solid line position in FIG. 9) due to the engagement relationship between the protrusion 72 and the engaging portion 75 as the rotating body 71 continues to rotate, and the protrusion 72 and the engaging portion 75 are then rotated. Since it is pushed back by the coil spring 77 when the engagement with is released,
The tilting body 57 is rotated in the backward direction by the fourth spring 61.

Therefore, the operation piece 31 is pushed by the lever 32 and the locking portion 63, which are engaged with each other, and the switch 30 is turned on.

At this time, the locking claw 68 of the locking device 64 falls and locks on the protrusion 69 of the lever 32, and the push state of the operation piece 31 is maintained.

When the switch 30 is turned on, the hydraulic pressure of the hydraulic pressure accumulator 25 causes the first cylinder 33 to act to clamp the support line 22 by the clamp device 28, so that the traveling body 21 stops traveling.

Further, since the engaging claws 51 are separated from each other by the action of the second cylinder 56, the engagement between the brim 47 and the engaging claws 51 is released.
The tip end side of the unwound retraction line 45 descends toward the ground (due to the weight of the brim 47 and the end hook B of the retraction line 45).

When the end of the tow line 45 is stopped on the load A and the load A is hoisted while the tow line 45 is wound up, the first slider 48 is pushed up by the brim 47 fitted in the pendulum 43 immediately before the end of the hoisting, and the above-mentioned push up is performed. 1 The slider 48 causes the locking device 64 to act via the operating device 84 to release the push state of the operating piece 31.

When the switch 30 is turned off in association with the above release, the first cylinder 33 and the second cylinder 56 do not work, and the third spring
The engaging claw 51 pulled by 54 is caught by the brim 47 to maintain the lifting state of the luggage A, and the clamp device 28 releases the holding of the support line 22.

At this time, the tip of the second slider 74 is located on the lower peripheral surface of the rotating body 71.

When the carried-out baggage A reaches the baggage unloading position, the rope 45 is unwound and the traveling body 21 is made to travel a little in the valley direction.
The cylinder 33 and the second cylinder 56 are operated.

As a result, the supporting device 22 is clamped by the clamp device 28, the engaging claws 51 are disengaged from the collar 47, and the tow line 45 is rewound to lower the luggage A.

When the pulling rope 45 is unwound after the luggage A is unloaded, the action of the first cylinder 33 and the second cylinder 56 is released and the traveling body 21 travels in the valley direction in the same manner as described above.

Further, as shown in FIG. 1 and FIG. 8, the upper end of the control lever 96 having a rotation fulcrum at the lower end is positioned below the tip of the rocking body 60, and the control lever 96 is pulled up by the spring 97 to lift the lever 32. The rocking body 60 is pulled up as shown by the chain line in FIG. 8 so that the engagement relationship between the upper end of the rocking body and the engaging portion 63 is released. When the hydraulic pressure of the hydraulic pressure accumulator 25 becomes equal to or higher than a set pressure, the control lever 96 is pushed down by the low pressure control device 98 so that the switch 30 is not turned on by maintaining the raised state of the lever.
If the upper end of 32 and the locking portion 63 are engaged with each other, safety can be guaranteed when sufficient pressure is not applied.

Further, as shown in FIGS. 7 and 11, a screw portion 99 is provided on the outer periphery of the shaft 73, and a screw hole 100 provided at the center of the rotating body 71 is screwed into the screw portion 99, and the pump of the shaft 73 is pumped. While mounting the annular plate 101 on the 24 side so as to be movable along the axis,
The annular plate 101 is fixed to a predetermined position of the shaft 73 by screwing the bolt 102, and the protrusion 72 is formed by traveling the mountain side of the traveling body 21.
And the engaging portion 75 are engaged with each other, the rotating body 71 is moved in the direction of the sprocket 26 with the rotation of the shaft 73, and the rotating body 71 and the boss portion 103 of the sprocket 26 face each other. When a certain first knock 104 is engaged, the rotating body 71 is rotated together with the shaft 73, and when the traveling body 21 travels in the valley direction, the rotation of the shaft 73 is maintained with the projection 72 and the engaging portion 75 engaged with each other. The rotary body 71 is moved in the direction of the pump 24 along with the movement, and the second knock 1 provided on the facing surface of the rotary body 71 and the annular plate 101.
If the rotating body 71 is rotated together with the shaft 73 when 05 is engaged, the time for tilting the tilting body 57 via the second slider 74 accompanying the running of the running body 21 can be adjusted.

With the above configuration, when using on a steep slope with a main rope length of 450 m or less, the time for tilting the tilting body 57 is short, and when the main rope length is 450 m or more and the slope is gentle, the pulling line droops. When the traveling body 21 is stopped by the force (weight of the wire rope), the traveling body 21 may be pulled back by the reaction that is stopped by the force. At that time, if the time to tilt the tilting body 57 is short, the next cycle pattern is entered and the hydraulic switch
Since 30 is included, the traveling body 21 cannot be stopped at an arbitrary position, and therefore it must be taken long considering the time (distance) to be pulled back. Therefore, by moving the annular plate 101, the traveling body 21 moves to transmit the rotational force from the rotary shaft 73 to the second slider 74, that is, the time of the engagement relationship performed by the repetitive motion of the traveling body 21. Can be adjusted.
