Abstract

Chokerring for the Attach the loop of a choker troop to transport an oblong Load attractable around the same loop, characterized that he bent with a at an angle a to the ring plane Approach (19) is connected, which has an elongated opening (20) for the passage of the Has loop (14) and that its peripheral surface (16) on the approach (19) opposite Side up in a wide sweeping downwardly bent flange (21) passes.

Description

The The present invention relates to a choker ring for attachment the loop of a choker troop, which is used to carry an oblong Last dressable around the same one is looped.

One known choker ring has two flanges, between which the ring surface with approximate semicircular Cross section for the reception of the loop is formed. So that the loop during the Transportes the load can not jump out, the loop becomes the choker troupe after making the choker ring yet used in the workshop in these and for security reasons then dowel pins regularly over the circumference of the flanges attached holes hammered, making Choker Ring and Choker Force one unit form. In this way, the loop is secured and even at a possible one Ring breakage can not pop out of the loop and thus the load get lost.

From the US 4,055,365 A a device has become known in which no loop but a straight end of the choker group is fixed in the bent part of the device. For this purpose, the end of the troop must be turned up and with a tool a fastening cone wrapped in this and further pushed into a cone-shaped opening in the bent part. In the US Pat. No. 3,795,952 a fastening device is described in which the fastening cable is wound at least twice around a hub and secured with a part connected to the hub. As with the known choker ring, the cable must already be used inextricably during the production of the fastening device. Next shows the US 2,946,619 A a double-acting fixing cable, the ends of which are clamped in a fixing block and whose center is wound around a steel eye, which is not comparable to a choker ring.

The Invention is now the task of creating a choker ring, in which the elaborate work of the hole drilling in the flanges and the subsequent driving the dowel pins no longer necessary is. Next is the loop of the choker troupe in a simple way can be used without the use of tools in the ring and while the load transport as before against the jumping out itself a possible one Ring fracture be secured.

These Task solves the choker ring according to the Generic term of the independent Patent claim 1, characterized in that it is at an angle A is connected to the ring plane bent approach, which has an elongated opening to the Slip through the loop and that its peripheral surface on the the approach opposite The top of the page merges into a wide, down-turned flange. Advantageous embodiments of the Subject of the invention are in the dependent claims 2 to 8 listed.

following is an embodiment of the invention Chokerrings explained in more detail with reference to the drawing. Show:

1 schematically the choker system, with which it is possible to support and use steep forests, especially in mountain areas

2 a Chokergehänge, which serves for hanging the Choker rings and

3 the inventive choker ring in the view from above and in side view.

The well-known choker system becomes the suspension cable 1 between suspension rope saddle 2 and drive 3 curious; excited. On the carrying rope 1 is the one with the pull rope 4 connected carriages 5 movably arranged. In the carriage 5 becomes the pull rope 4 deflected, with at its end the Chokergehänge 6 is attached.

Around the trees or tree trunks to be transported 7 becomes a choker troupe 8th wrapped, with a anziebare noose 9 is formed while the the end of the choker troupe 8th forming loop already on the choker ring 10 attached and secured by dowel pins. The rotatably mounted tail 11 of the choker hanger 6 gets through the opening of the choker rings 10 until all choker rings are lined up on the choker hanger.

There for collecting the tree pieces the carriage is blocked on the carrying rope, now can the pull rope be attracted, making all choker rings to lie on the tail of the Chokergehänges come. When moving on, a tree piece package is formed that far is pulled until it is vertically under the carriage free in the air hangs. Now the trolley is deblocked and the tree piece package with the pull rope to the Transporting loading point, which is located on a ridge crossing the carrying rope. From here, the pieces of trees by means of Trucks transported to the valley.

The choker hanger 6 is in 2 shown enlarged, where already two inventive choke rings 10 lined up. In the choker spindle 12 is the end of the pull rope 4 and a chain 13 attached to the the tail 11 is rotatably mounted. By turning the tail 11 in Lämgsrichtung the chain 13 are the choker rings 10 been retracted, and they no longer slide out after turning back the tail in the transverse direction can.

The inventive choker ring 10 is in 3 with inserted loop fourteen the choker troupe 8th shown in large scale. It encloses a circular opening 15 with a diameter D of such size that the tail 11 can be easily inserted in the longitudinal direction, but in its transverse position of the choker ring is held securely in the Chokergehänge.

The peripheral surface 16 for receiving the loop fourteen gets down from a flange 17 limited, over two side walls 18 with a bent at an angle a to the choker ring approach 19 connected is. The approach 19 has an elongated opening 20 for passing the loop fourteen on. Above shows the peripheral surface 16 on the approach 19 adjacent flange on no side, while on the opposite side of the approach, the peripheral surface approximately over half the circumference of the ring in a far-reaching bent down flange 21 passes. The flange 21 also has a projecting right-angled flap at its center 22 on, deart that a hollow for the tightrope of the loop fourteen is formed.

For inserting the loop fourteen in the choker ring 10 The loop is simply squeezed and pushed through the opening 20 of the approach 19 from oblique bottom up over the choker ring. Then the loop is bent down and by pulling back on the peripheral surface 16 put on and under the rag 22 encountered. In this way, the loop of the choker troop can not pop out when the load is suspended and even with a ring break the loop still holds the ring together, so that the load is held further.

Because of Heavy use in rough forest operation is made by the choker ring made of metal, wherein it is advantageously made of cast metal becomes.
