Motor transport guard comprises supporting folding structure composed of crossed bands articulated at cross points and at the ends to make scissor mechanism and damaging elements composed by detachable tenons fitted on pins. Said tenons are composed of tubes with the cut made at tenon top at the angle of 15-45 degrees to tenon lengthwise axis. Note here that tenon ID makes 0.50-0.95 of tenon OD Pins feature height of 0.2-0.8 of tenon height and diameter of 0.75-0.95 of tenon ID. |

Retainer for arresting chased car (versions) and method of flattening rear tire Proposed retainer thrown from chasing car toward chased car comprises flexible cable and two propellant weights fastened at the ends of said flexible cable. Said propellant weights are spaced apart an allow their release from chasing car toward chased car, tight to its rear wheel. In aiming, rear wheel should be located between said two propellant weights. The latter catch rear tire to flexible cable block rear wheel by winding around rear tire. In compliance with another version, proposed retainer comprises multiple segments, each articulated with adjacent segment to form a chain. Method of flattening rear tire consists in using aforesaid retainer to stop chased car provided with multiple thorns arranged on cable between weights to flatten rear tire. |

Proposed traffic barrage comprises N pairs of crossed plates, injurious elements, box and barrage length limiters (BLL). Plates of every aforesaid pair are pivoted together at their centers while their ends are hinged to the ends of crossed plates. BLL are pivoted between the ends of adjoining crossed plates, each BLL being made up of two adjoining plates with their ends also pivoted together. Injurious elements are fitted on hinge axles. N pairs of crossed plates are arranged as-folded in box inner space. Springs are arranged on aforesaid hinge axles located at crossed plates centers and between them to allow said plates to unfold. First pair of crossed plates is attached to box face walls. Box front wall lower edge is hinged to box bottom and furnished with retainer to hold crossed plates in folded state, and with retainer unlocking device. |

Anti-collision device (variants) Device comprises support pivotally connected with fastening means, which secures device to gate leafs. Device in accordance with the first embodiment comprises beam hinged to support, wheel movably connected to beam and resilient member secured to beam by one end. Device in accordance with the second embodiment comprises slide moving along support, wheel movably connected to slide and resilient member fastened to slide by the first end thereof. Another end of resilient member is secured to fastening unit or to support. Resilient member may be made as curvilinear beam or spring. In the second embodiment resilient member made as spring may be put on support. |

Motor vehicle barrier structure Barrier comprises N pairs of crossing plates, shocking members and base. Plates of each pair are pivotally connected with each other in plate centers. Plate ends are pivotally attached to that of adjacent plates. Shocking members are supported by hinge pins. N pairs of crossing plates are collapsed and laid on the base. Springs facilitating plate erection are installed on hinge pins located in plate centers and arranged between the plates. The first plate pair is secured to base provided with retaining means to secure plates in collapsed state and with retaining means releasing member. |

The pit-fall represents a pit on the road covered by a slab installed on supports. At an attempt to break-through to the guarded territory the supports get broken down, and the transport facility-trespasser falls to the pit bottom together with the slab. In case of a blasting of the mine-strewn transport facility the main affecting action of the blast (fragmentation and high-explosive) is directed upwards causing minimum possible injuries to people, as well as to the adjacent buildings and structures. |

Barricade comprises base and collapsible barrier made as multijoint articulated mechanism with pair of wheels. The mechanism is composed of crossing plates pivotally connected one to another in crossing points and at ends thereof, arresting members made as spikes installed on hinge axes, and barrier extending mechanism. The barrier extending mechanism comprises cylinder with piston and rod and compressed gas source. The barrier is provided with protective case having front lid for wheel semi-axles concealment. Front end of collapsible barrier is connected with rod by corbel provided with load on the first corbel end. The corbel has horizontal shelf with cut and orifice adapted to receive fingers of the first multijoint articulated mechanism link ends. |
