Description

465 266 10 15 Fig. 1 visar en schematisk skiss av uppfinningen i oaktive- rat läge. 465 266 10 15 Fig. 1 shows a schematic sketch of the invention in inactive rat mode.

Fig. 1 visar en schematisk skiss, enligt uppfinningen, sedd i oaktiverat kretslöst tillstànd, där hydraulmotorn A kan cirkulera olja genom en tvåvägsventil C och en strypning B, då kranen skall kunna placera sig själv i vindriktningen.Fig. 1 shows a schematic sketch, according to the invention, seen in the inactivated circuitless state, where the hydraulic motor A can circulating oil through a two-way valve C and a throttle B, then the crane must be able to place itself in the wind direction.

Vid funktion aktiveras en styrventil D för att starta vri- drörelsen, varvid ventilen C kan aktiveras eller stanna kvar i det visade läget, beroende pá om all olja önskas till motorn A vid kraftfull start eller om det önskas en mera mjuk start med tryck-och flödesreducering genom strypningen 8. ut., .PDuring operation, a control valve D is activated to start the rotary the movement, whereby the valve C can be activated or remain in the position shown, depending on whether all oil is desired engine A at powerful start or if more is desired soft start with pressure and flow reduction through the choke 8. out., .P

10 15 465 266 3 PATENTKRAV10 15 465 266 3 PATENT REQUIREMENTS 1. Hydrauliskt svängbart system för svängkran. med shuntventil insatt i tryckledningar till en svängningsmotor, så att olja kan cirkulera utanför svängningsmotorn, k ä n n e t e c k n a t d ä r a v, att shuntventilen är utförd med sådan karaktäristik, att kran- bommen, när kranen inte är i drift eller vid fel i kraftöver- föringskretsloppet under drift, på lämpligt, utbromsat sätt, placeras i vindriktningen.1. Hydraulically swivel system for swivel crane. with shunt valve inserted in pressure lines to a swing motor, so that oil can circulate outside the swing motor, characterized in that the shunt valve is designed with such characteristics that the crane boom, when the crane is not in operation or in the event of a fault in the power transmission circuit during operation, in a suitable, decelerated manner, is placed in the wind direction. 2. Hydrauliskt svängbart system för svängkran enligt patentkravet l, k ä n n e t e c k n a t att det vid behov av speciellt stor Överförd kraft eller då temporärt kan åstadkommas en d ä r a v, motorn skall verka som broms, stängning av shuntledningen från kranens manöverpanel. Pl3874SE-BW-8910092. Hydraulically swivel system for swivel crane according to claim 1, characterized in that in the event of a need for a particularly large transmitted force or when a temporary one can be produced temporarily, the engine must act as a brake, closing the shunt line from the crane control panel.
