Abstract

The invention relates to a rotator for a hydraulic tool, such as a jib-carried hydraulic tool. The rotator (100) comprises: a stator (110) comprising at least one first hydraulic port (142) configured to be connected to a hydraulic tool (300) via at least one first hydraulic hose (152); a rotor (120) rotatably arranged inside the stator (110); and a hydraulic swivel (130) comprising a hydraulic housing (132) rotatably arranged around the stator (110) and/or an centre axis (112) of hydraulic swivel (130), the hydraulic housing (132) comprising at least one second hydraulic port (144) configured to be connected to a hydraulic source (220) via at least one second hydraulic hose (154), wherein the second hydraulic port (144) is connected to the first hydraulic port (142) via at least one internal hydraulic channel (146) extending inside the hydraulic housing (132) and the stator (110) and/or between the hydraulic housing (132) and the stator (110). The invention also relates to a vehicle comprising such a rotator.(Fig. 1a and 1b)
