[CN 201980045787.4] Working equipment with hydraulic cylinders and hand-held working equipment, such as pliers or presses Title: Working equipment with hydraulic cylinders and hand-held working equipment, such as pliers or presses Application number: CN 201980045787.4 Applicant: Gustav Crocker Co., Ltd. Application date: 2019-5-16 Patent type: Invention application The present invention relates to a hydraulically operated working equipment (1), it has a hydraulic cylinder (13), a hydraulic piston (12) movable in the hydraulic cylinder (13), a drive unit (2) with a motor (9) and a pump (8), and a hydraulic line (16) leading to the hydraulic cylinder (13). In order to further improve the working equipment of the aforementioned type, in particular in terms of safety technology, it is proposed that the hydraulic cylinder (13) is constructed in an electrically insulated manner relative to the drive device component (2), for which an electrically insulated isolation layer (19) is provided, which traverses the working equipment (1), for electrically separating the hydraulic cylinder (13) from the drive component (2) in the region of the end of the hydraulic cylinder (13) facing the drive component (2), the hydraulic line (16) being guided through the insulating layer (19) when the partial region (26) of the hydraulic line (16) is formed from an electrically insulating material.
