FIELD: machine engineering.
SUBSTANCE: device for assembly or disassembly flange connections, including pins and nuts, contains pin extraction devices with hydraulic cylinders and rods with nuts installed on the base. Each pin extraction device is made in the form of a hydraulic cylinder perpendicular to the extracted pin. The body and piston of the hydraulic cylinder are connected to pairs of levers, supported on two support platforms with axes. One of the support platforms is made interacting through the base with one of the flanges, and the second - with the nut installed on the rod.
EFFECT: simplified and cheaper construction.
