Abstract

See full text

The present invention relates to a hydraulic attachment comprising a hydraulic circuit, the attachment being a construction or demolition tool, in particular a hydraulic breaker, demolition shears, scrap shears, a pulverizer, a gripper, a crusher bucket or a compactor, which can be mechanically connected to a support device and hydraulically connected to the hydraulic system of the support device. In order to enable the hydraulic circuit to be opened quickly and safely within an attachment and, in particular, to make it possible to display the presence of a particular pressure level within a hydraulic attachment and to determine whether a dangerous residual pressure is present in the system, a hydraulic attachment is proposed that has a residual pressure display (40) which is connected to the hydraulic circuit of the attachment in a detachable or non-detachable manner.
