Abstract

The invention relates to a hand-held pulling and compression device and a hydraulic force amplifier for a hand-held pulling and compression device for driving pulling and pressing tools. In order to provide a hydraulic force amplifier for an electro-mechanically driven, hand-held pulling and compression device and a hand-held pulling and compression device which can be easily and flexibly adapted to different operations, it is provided that the hydraulic force amplifier has a housing body having at least one first working chamber filled with hydraulic fluid and having a connecting section for detachably fixing the hydraulic force amplifier to a connection section of the pulling and compression device. In addition, the hydraulic force amplifier has a first hydraulic piston which is arranged in the first working chamber so as to be displaceable between a starting position and an end position and which has a first piston surface and a coupling section for connection to a drive element of the pulling and compression device which is adjustable relative to the connection section. Furthermore, the hydraulic force amplifier has a second hydraulic piston which is displaceably arranged in the working chamber at a distance from the first hydraulic piston and has a second piston surface which is larger than the first piston surface and a mechanical tool connection for the pulling and pressing tool.
