Definitions
- the present invention relates to a releasable strap to be used with a hauling system, particularly for transport of felled trees in the forest. More precisely, the invention relates to a releasable strap for a hauling system of the kind which comprises an elongated element which runs along the transport line and is movable back and forth by means of a drive mechanism, and a plurality of releasable carriers adapted to be attached to the element at any desired positions.
- the object of the invention has been to provide a releasable strap which enables release of the load at a predetermined location.
- the releasable strap accord- ing to the invention is characterized in that the strap comprises a flexible element which is adapted to be connected to a carrier and is provided with an automatic ⁇ ally openable locking mechanism for releasable locking of one end of the flexible element in such a manner that the element forms a load-surrounding loop , said locking mechanism being adapted to be opened to release the load by moving the strap against a stationary actuating means.
- Fig. 1 is a perspective view of one part of the releasable strap according to the invention ?
- Fig. 2 is a side view of one portion of a hauling system wherein the releasable strap according to the invention is utilized;
- Fig. 3 is an end view, corresponding to Fig. 2, of the hauling system.
- a hauling system comprising a reciprocating hauling rope 10 to which carriers 11 may be attached at any desired points along the length of the rope.
- the carriers are designed in such a manner that they are brought along with the rope as the rope is moved in one direction, whereas they slip in relation to the rope as this is moved in the opposite direction.
- a releasable strap according to the invention, generally denoted 12.
- the releasable strap 12 is connected to a load, in the present case embodied by a log 13.
- a releasing means, generally denoted 14, is adapted to actuate the releasable strap to release or open it at the unloading station, so as to release the load.
- the releasable strap comprises a string 15 or any other similar flexible element which is connected to the carrier 11 in a manner not shown and which is provided with a locking mechanism 16.
- the locking mechanism 16 is movable carried by the flexible element 15 to permit positioning thereof at any desired distance from the outermost end of the element 15.
- the outermost end of the string is provided with a ring 17 or the like for engagement with the locking mechanism 16.
- the locking mechanism 16 comprises two mutually movable parts 18 and 19, one part 19 of which has an opening 20 to receive the ring 17, whereas the other part 18 is provided with a lock element 21 to either lock or unlock the opening 20.
- the parts 18 and 19 are spring biased into such a mutual position that the lock element 21 locks the opening 20 with the lock element 21 passing through the ring 17 and with the ring extending into the opening 20.
- the release means 14 is embodied by a hexagonal ring through which the hauling rope 10 extends and which is provided with protrusions 22 pointing opposite the transpor- t direction. If desired, the protrusions may be comparat ⁇ ively stiff but still flexible. in operation the releasable strap is placed round a log 13 and then the strap is connected to the hauling rope 10 by means of the carrier 11. In the example shown it is contemplated that the logs are transported from the left to the right as seen in Fig. 2.
