Description

vsoszço-1 10 15 20 2 ~Vid parkering av kranen förfares på omvänt sätt, dvs teleskopbommen 7 dras in och dess nedre del med _ tappen 8 bringas i linje med slitsen i hållaren 9, var- efter tappen 8 införes i slitsen för att fasthállas i denna. Detta läge visas i fig. 2. Därefter förskjutes hyl- san 5 nedåt på vippbommen 6 till det i fig. 1 visade läget,~ varigenom kranen är läst i parkeríngs1äget.' Vippbommen 6 kan alternativt förses med flera läs- hål 11", vilket medför större variation i bomlängd och- därmed förbättrade egenskaper hos kranen: Vippbommen 6 kan också förses med en cylinder för att erhålla en teleskoprörelse i hylsan 5, varvid undvikas det ovannämnda, omständliga sättet att föra bommen till operations- resp parkeringsläge. Detta utförande är emel- lertid dyrare. 7 De mest väsentliga kännetecknen hos kranen enligt L uppfinningen är att vippbommen 6 kan glida fram och tillf- paka-i hylsan 5, som är anordnad vid huvudbommens 3 yttre ände, och kan fastlásas i önskade lägen, 11, 11', 11" och 12, och att en låsanordníng 8, 9 är anordnad för vippbom- mens 6 yttre ände vid lasthilens sida (kranens stödben) för att hålla fast kranen i parkeringsläge och fastlåsa vippbommen B under dennas förskjutning relativt hylsan É vid huvudbommens 3 ände. , 1 vsoszço-1 10 15 20 2 ~ When parking the crane, the procedure is reversed, ie the telescopic boom 7 is retracted and its lower part with the pin 8 is aligned with the slot in the holder 9, after which the pin 8 is inserted into the slot to be held. in this. This position is shown in Fig. 2. Thereafter, the sleeve 5 is displaced downwards on the rocker bar 6 to the position shown in Fig. 1, whereby the crane is read in the parking position. The rocker boom 6 can alternatively be provided with several reading holes 11 ", which leads to greater variation in boom length and thus improved properties of the crane: The rocker boom 6 can also be provided with a cylinder to obtain a telescopic movement in the sleeve 5, thus avoiding the above-mentioned, cumbersome This design is, however, more expensive.7 The most important characteristics of the crane according to the invention are that the rocker boom 6 can slide forward and pack in the sleeve 5, which is arranged at the main boom 3. outer end, and can be locked in desired positions, 11, 11 ', 11 "and 12, and that a locking device 8, 9 is arranged for the outer end of the rocker boom 6 at the side of the load hile (crane support legs) to hold the crane in parking position and locking the rocker boom B during its displacement relative to the sleeve É at the end of the main boom 3. , 1
