FIELD: construction engineering; mechanization of jobs pertaining to dismantling pipe lines provided with faucet joints. SUBSTANCE: proposed device has carriage and pipe feed mechanism which are interconnected by means of rocker arm fitted with dampening spring mounted on frame. Located along lateral sides of carriage are racks which are rigidly connected with frame. Release mechanism with grips is mounted on carriage. When frame moves forward, grips of carriage rest against faucet of joint moving it backward, thus releasing the locking rings of joint and impacting grips against faucet. EFFECT: extended field of application. 2 dwg
