A method is for operating an electromechanical or electrohydraulic work appliance or rescue appliance that can be carried and used by an operator, having a movable tool insert, a spreading tool or a lifting tool, a housing, an electric motor, a pump or a mechanical transmission driven by the electric motor, for actuating the tool insert. The appliance has an exchangeable, rechargeable appliance electrical energy source, having a housing in or on the rescue appliance. During operation of the appliance, operating data of the appliance and/or of the energy source are acquired and transferred into a data carrier or data storage device in the electrical energy source. The electrical energy source is removed from the appliance and connected to a charging device. The operating data stored in the data carrier or storage device of the electrical energy source are read by the charging device and transferred to a network.

Method for operating a work appliance or rescue appliance, work appliance or rescue appliance, and energy source

A shear blade () is for a portable hydraulic cutting device, such as a rescue device having a blade body (). The blade body () has an assembly region () and a cutting region (), a cutting edge () in the cutting region (), a contact surface (), located on one side of the cutting edge (), for an additional shear blade. An outer surface (), located on the other side of the cutting edge (), is provided to act on the object to be cut. The cutting region () has a recess () for receiving a cutting insert (). The recess () is configured such that the cutting insert () is insertable into the recess () at an acute angle &#x3b4; to the contact surface () of the shear blade ().

Shear blade for a cutting tool

A shear blade is for a portable hydraulic cutting device having a blade body. The blade body has assembly and cutting regions, with a cutting edge in the cutting region. A contact surface is on one side of the cutting edge for an additional shear blade. An outer surface on the other side of the cutting edge acts on the object to be cut. A first surface portion of the outer surface extends away from the cutting edge along an orthogonal, which meets the contact surface at the cutting edge, or at an acute angle &#x3b1; relative to the orthogonal. A second surface portion connects to the first surface portion at an acute angle &#x3b2; to the orthogonal. A third surface portion connects to the second surface portion at an acute angle &#x3b3; to the orthogonal. Angle &#x3b1; is smaller than angle &#x3b2;, which is smaller than angle &#x3b3;.

Shear blade and cutting device

A hydraulic implement () for portable use includes a hydraulic pump (), a pump housing (), a hydraulic cylinder () with a piston rod (), a hydraulic tank (), hydraulic lines, a compensating device, a manually operable hydraulic control valve (), a rechargeable battery () which is accommodated on the implement (), and two tool halves () that are connected to the piston rod () via pivoting arms (). Each tool half () has a wall section () that extends perpendicularly to the extension of the longitudinal axis of the piston rod (). When the tool halves are closed, both wall sections () together form a flattened end region () that runs perpendicularly to the extension of the longitudinal axis of the piston rod ().
