FIELD: transport engineering. ^ SUBSTANCE: invention relates to servicing of vehicles. Proposed device has spur reduction gear with driving gear 4 and driven 5 mechanically connected with electric motor 3, Driven gear 5 is mounted on spindle 6 which is installed in split bearings 7 installed on framework 8. Spindle 6 is made hollow for accommodating wrench installed for locking from turning. Angle cock locking unit 11 is installed coaxially to spindle 6 in vertical plane for longitudinal displacement in guides 12 located on framework 8. Slots 13, 14 are made in the same plane at opposite sides in angle cock locking unit 11. Slots are made for fitting angle cock body with union in one slot 13, and body of angle cock with main line tap in other slot 14 in which round rod 18 is installed with tilting for inner diameter of said tap. ^ EFFECT: simplified design, improved reliability. ^ 3 dwg |
