OPENTECHNICAL PUBLICATION OT-2026-000002632 Working device having a hydraulic cylinder and manual working device such as a pliers or a press Published: 2026-09-15T19:14:19.586797Z Permanent URL: https://opentechnical.org/p/OT-2026-000002632 Categories: Tools & Tooling > Clamping Tools ------------------------------------------------------------------------ ABSTRACT A hydraulically actuated working device having a hydraulic cylinder, a hydraulic piston that can be displaced in the hydraulic cylinder, a drive unit part which has a motor and a pump, and a hydraulic line leading to the hydraulic cylinder. The drive unit part is designed in an electrically insulating manner, to provide an electrically insulating separating layer, which passes through the working device in a crossing manner for electrical separation from the working device part with respect to an end of the hydraulic piston facing the drive unit part. The hydraulic line is guided through the separating layer, thereby also forming a partial region of the hydraulic line made of an electrically insulating material. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000002632 Published 2026-09-15T19:14:19.586797Z https://opentechnical.org/p/OT-2026-000002632
