Abstract
(EN) The invention relates to a rotator (100) for a tool, such as a as a jib-carried tool. The rotator (100) comprises: a stator (102); a rotor (104) rotatably arranged inside the stator (102); a bearing (112) configured to carry an external load (L); a lower link (150) for attaching a tool (200) to the rotator (100); and a load cell (180) arranged between the bearing (112) and the lower link (150), wherein the load cell (180) is configured to indicate the external load (L). Thereby, a rotator (100) compact in its axial extension can be provided.
(FR) La présente invention concerne un dispositif de rotation (100) pour un outil, tel qu'un outil porté sur flèche. Le dispositif de rotation (100) comprend : un stator (102); un rotor (104) agencé de façon rotative à l'intérieur du stator (102); un palier (112) configuré pour porter une charge externe (L); une liaison inférieure (150) pour fixer un outil (200) au dispositif de rotation (100); et une cellule de charge (180) agencée entre le palier (112) et la liaison inférieure (150), la cellule de charge (180) étant configurée pour indiquer la charge externe (L). Ainsi, un dispositif de rotation (100) compact dans son extension axiale peut être fourni.
