FIELD: technological processes.
SUBSTANCE: invention relates to procedure of manifold pipelines operation and may be used in oil, gas and other industries. Invention comprises frame with guides, sliding tray and pusher installed on movable trolley. Frame consists of two levels. Lower level is fixed to chamber. Upper level rests on lower level via step-bearing and system of wheels. On it there are guides installed for movement of tray with missile and pusher trolley. Tray consists of three parts. Central part is cylindrical half-shell with open upper part. Front part facing chamber is intended for "front" reeving of missiles. Back part represents flat sliding bottom, on which windows are arranged for product passage. Pusher represents mechanism of reciprocal linear motion with working element in the form of sliding stem. To control alignment, optical accessory is used.
EFFECT: invention makes it possible to prevent locking of missiles at start-up, shifting and jamming of missiles and tray inside chambers at start-up and withdrawal operations, also to reduce share of manual labour.
