Abstract

Ett portabelt hydraulaggregat (100) för att förse en ansluten hydraulmaskin med hydraultryck samt flöde genom en anslutning (52) är tillhandahållet. Det portabla hydraulaggregatet (100) innefattar: en reservoar (58), ett pumpsystem innefattande åtminstone en första pump (72) och en andra pump (74), som är anordnade att pumpa hydraulvätska från nämnda reservoar (58) till nämnda anslutning (52), en elektrisk motor (20) som är konfigurerad till att driva pumpsystemet, och ett justerbart ventilsystem (60) som är konfigurerat till att selektivt avleda vätskeflödet från den andra pumpen (74).A portable hydraulic unit (100) for supplying a connected hydraulic machine with hydraulic pressure and flow through a connection (52) is provided. The portable hydraulic assembly (100) comprises: a reservoir (58), a pump system comprising at least a first pump (72) and a second pump (74), which are arranged to pump hydraulic fluid from said reservoir (58) to said connection (52) , an electric motor (20) configured to drive the pump system, and an adjustable valve system (60) configured to selectively divert fluid flow from the second pump (74).
