ABSTRACT:
The invention relates to an electrohydraulic pressing device (1) that can be operated using one hand. The device comprises a working head (30), an electric motor (4), a pump (20), a hydraulic reservoir (33), and a gear mechanism (19) extending between the electric motor (4) and the pump (20). A holding area (5) around which a hand is placed is provided and an actuating switch (39) is assigned to this area. The aim of the invention is to improve a pressing device of this type with regard to the handling thereof. To this end, the invention provides that the holding area (5) is formed around the electric motor (4), and the actuating switch (39) is situated between the electric motor (4) and the working head.
