Razen tega prijavitelju znano stanje tehnike predstavljajo žičnice iz US 4 005 779 A, GB 2 053 128 A, EP 0 161 437 A2, US 3 283 454 A, US 2 790 622 A in WO 2004/076255 Al.In addition, the prior art is represented by cableways of US 4,005,779 A, GB 2,053,128 A, EP 0 161,437 A2, US 3,283,454 A, US 2,790,622 A and WO 2004/076255 A1.

Gozdarska žičnica, ki je opisana v EP 0 161 437 A2, obsega mobilen pogonski sklop ter voziček, ki je premakljiv vzdolž nosilne vrvi in obsega vsaj dve nosilni vrvenici za naleganje vozička na nosilni vrvi in vodenje vozička med premikanjem vzdolž omenjene nosilne vrvi, kot tudi vsaj dve vodilni vrvenici, ki sta v vertikalni smeri žičnice razporejeni pod omenjenima nosilnima vrvenicama in sta prirejeni za vodenje povratne vrvi preko vozička, razen tega pa tudi podporno vrvenico, kije v vertikalni smeri žičnice razporejena pod in med omenjenima vodilnima vrvenicama in je predvidena za podprtje in vodenje vlečne vrvi vključno z vsakokrat razpoložljivim bremenom. Žičnica nadalje obsega nosilno vrv, ki poteka od pripadajočega bobna v ogrodju pogonskega sklopa preko preusmerjevalne vrvenice na stebru do prve fiksne točke na terenu, na katero je pripeta, pri čemer je omenjena nosilna vrv prirejena za zagotavljanje podpore in za vodenje vozička, namreč podpornih vrvenic vozička. Še nadalje žičnica obsega povratno vrv, ki poteka od pripadajočega bobna v ogrodju pogonskega sklopa preko preusmerjevalne vrvenice na stebru in preko vodilnih vrvenic na vozičku do nadaljnje preusmerjevalne vrvenice v neposredni bližini omenjene prve fiksne točke in od ondod nazaj proti vozičku, na katerega je pripeta. Poleg navedenega žičnica obsega tudi vlečno vrv, ki poteka od pripadajočega bobna v ogrodju pogonskega sklopa preko preusmerjevalne vrvenice na stebru in omenjene podporne vrvenice na vozičku ter naprej proti vsakokrat razpoložljivemu bremenu, s katerim je vlečna vrv po izbiri povezljiva. Razen tega žičnica obsega tudi vsaj dve napenjalni vrvi, ki potekata med napenjalno vrvenico na od podlage bolj oddaljenem koncu nosilnega stebra in vsaj dvema nadaljnjima fiksnima točkama, ki se nahajata na podlagi izven območja traktorja in pogonskega sklopa, prednostno vsaj približno v nasprotno smer od omenjene prve fiksne točke in primemo vsaksebi zaradi sidranja stebra v njegovem pokončnem položaju med vleko bremena.The forestry cableway described in EP 0 161 437 A2 comprises a mobile drive assembly and a trolley movable along the support rope and comprising at least two support ropes for the trolley to rest on the support rope and guide the trolley while moving along said support rope, as well as at least two guide ropes arranged in the vertical direction of the cableway under said support ropes and adapted to guide the return rope through the trolley, as well as a support rope which is arranged in the vertical direction of the cable under and between said guide ropes and is intended to support and guiding the tow rope including the load available at all times. The cableway further comprises a support rope extending from the associated drum in the drive assembly frame via a deflection rope on the column to the first fixed point on the ground to which it is attached, said support rope being adapted to provide support and guide the trolley, namely support ropes. trolley. Furthermore, the cableway comprises a return rope running from the associated drum in the drive assembly frame through the diverting rope on the column and through the guide ropes on the trolley to a further diverting rope in the immediate vicinity of said first fixed point and from there back to the trolley to which it is attached. In addition to the above, the cableway also comprises a tow rope running from the associated drum in the drive assembly frame through the deflection rope on the mast and said support rope on the trolley and onwards towards the load available to which the tow rope is optionally connected. In addition, the cableway comprises at least two tensioning ropes running between the tensioning rope at the end of the support column and at least two further fixed points located on the base outside the tractor and drivetrain area, preferably at least approximately in the opposite direction from said the first fixed points and grip each other due to the anchoring of the column in its upright position during towing of the load.

Sam pogonski sklop žičnice obsega nosilni steber, ki je na svojem od podlage bolj oddaljenem koncu opremljen s prosto vrtljivimi preusmerjevalnimi vrvenicami za vodenje nosilne vrvi za podpiranje in vodenje vzdolž omenjene nosilne vrvi premakljivega vozička, kot tudi za vodenje povratne vrvi za premikanje omenjenega vozička in obenem tudi za vodenje preko omenjenega vozička potekajoče vlečne vrvi za vleko vsakokratnega bremena. Pogonski sklop nadalje obsega tudi ogrodje z integriranimi navijalnimi bobni za navijanje oz. prejem nosilne vrvi, povratne vrvi in vlečne vrvi.The drive assembly of the cableway itself comprises a support column, which at its end further from the ground is equipped with freely rotating diverting ropes for guiding the support rope for supporting and guiding along said support rope of the movable trolley, as well as for guiding the return rope for moving the trolley. also for guiding a tow rope passing through said trolley to tow each load. The drive assembly further comprises a frame with integrated winding drums for winding or. receiving support rope, return rope and tow rope.

Prijavitelju je nadalje znano, da je pogonski sklop nameščen na podvozju s kolesi, sodobne komercialno dostopne tovrstne žičnice proizvajalcev gozdarskih vitlov in druge opreme pa so opremljene z vlečnim rudom, ki je členkasto povezano z omenjenim ogrodjem in nosilnim stebrom in je v osnovi predvideno za povezavo pogonskega sklopa s traktorjem zaradi vleke pogonskega sklopa po terenu in tudi za vsaj začasno zadrževanje pogonskega sklopa s pomočjo traktorja v vsakokrat izbranem položaju. Pri najsodobnejših znanih žičnicah je z omenjenim rudom členkasto povezan hidravlični cilinder, ki je po drugi strani členkasto povezljiv s tritočkovnim mehanizmom traktorja in s katerim je omogočeno nagibanje pogonskega sklopa s stebrom v vzdolžni smer žičnice, razen tega pa so tovrstne žičnice opremljene tudi s podvozjem s kolesoma, ki pa je prirejeno za premikanje pogonskega sklopa s stebrom in ogrodjem v smislu vleke s pomočjo traktorja po vsakokrat razpoložljivi podlagi. Omenjeno rudo med postavljanjem nosilnega stebra omogoča nagibanje stebra v vzdolžni smeri, pri čemer pa je sam steber tako med postavljanjem žičnice kot tudi kasneje med samo uporabo razporejen na odmiku od podlage, tako da se obremenitve s stebra na podlago prenašajo bodisi preko koles podvozja, ali pa kvečjemu preko ogrodja pogonskega sklopa, ki pa je pri omenjenih žičnicah zasnovano podobno kot pri gozdarskih vitlih, tako da je naleganje ogrodja na podlagi linijsko. Tovrstna rešitev kot rečeno omogoča nagibanje stebra v vzdolžni smeri, ne pa tudi v prečni smeri. V praksi žičnico pogosto postavljajo na neravnem terenu, zato je tovrstno podprtje razmeroma močno obremenjenega nosilnega stebra še zlasti brez možnosti niveliranja v prečni smeri razmeroma neugodno tako v pogledu same stabilnosti kot glede možnosti posedanja ali ugrezanja pod obremenitvijo, ki ji je med vleko bremena steber kasneje med uporabo izpostavljen.It is further known to the applicant that the drive assembly is mounted on a wheeled chassis, and modern commercially available lifts from forestry winches and other equipment are equipped with a drawbar, which is articulated to said frame and support column and is basically intended for connection. of the drive assembly with the tractor due to the traction of the drive assembly on the ground and also for at least temporary restraint of the drive assembly by means of the tractor in the position selected in each case. In the most modern known lifts, a hydraulic cylinder is articulated to the said ore, which on the other hand is articulated to the three-point mechanism of the tractor and which enables tilting of the drive assembly with a column in the longitudinal direction of the lift, and such lifts are also equipped with a chassis. wheels, which is adapted to move the drive assembly with the column and frame in terms of traction by means of a tractor on each available surface. Said ore during the installation of the supporting column allows the column to be tilted in the longitudinal direction, whereby the column itself is distributed at a distance from the base both during the installation of the cable car and later during use, so that loads from the column to the base are transmitted either via chassis wheels, or but at most through the frame of the drive assembly, which in the mentioned lifts is designed similarly to the forestry winches, so that the bearing of the frame on the base is linear. This type of solution, as said, allows the column to be tilted in the longitudinal direction, but not in the transverse direction. In practice, the cableway is often placed on uneven terrain, so this kind of support of a relatively heavily loaded load-bearing column, especially without the possibility of leveling in the transverse direction, is relatively unfavorable both in terms of stability and the possibility of sitting or sinking under load. exposed during use.

Razen tega je v WO 2004/076255 Al opisana mobilna naprava s podpornim stebrom za postavitev klasične žičnice, pri kateri je nosilni steber podprt na štirih vsaksebi štrlečih teleskopskih nogah, s pomočjo katerih je možno vzdrževanje nosilnega stebra v pokončnem položaju, nagibanje oz. niveliranje stebra v vseh smereh in tudi premikanje omenjenega stebra po terenu. Tudi pri tovrstni rešitvi je sam steber razporejen na odmiku od podlage, razen tega pa naprava samohodna in potemtakem opremljena z lastnim pogonskim agregatom, predvidena pa je izključno za podpiranje nosilne in vlečne vrvi žičnice brez možnosti manipuliranja s samim bremenom. V ta namen je naprava lahko opremljena s posebno teleskopsko roko, s pomočjo katere je možno rokovanje z bremenom v razmeroma majhnem območju okoli same naprave.In addition, WO 2004/076255 A1 describes a mobile device with a support column for the installation of a conventional cableway, in which the support column is supported on four protruding telescopic legs, by means of which it is possible to maintain the support column in an upright position. leveling the column in all directions and also moving said column across the terrain. In this type of solution, the column itself is located at a distance from the ground, in addition, the device is self-propelled and therefore equipped with its own drive unit, and is designed exclusively to support the supporting and traction rope without the possibility of manipulating the load. For this purpose, the device can be equipped with a special telescopic arm, with the help of which it is possible to handle the load in a relatively small area around the device itself.
