Designed for constructing bridge crossings over obstacles up to 3 m deep in order to pass through them tracked vehicles weighing up to 60 tons and wheeled vehicles with a pressure of up to 11 tons per axle. With the help of one TMM-3 set it is possible to: — build four single-span bridges over an obstacle up to 9.5 m wide and with unlimited depth; — construction of two bridges of two spans to overcome obstacles up to 19.5 m wide and up to 3 m deep in the middle; — construction of one three-span or one four-span bridge with an obstacle width of 30.0 and 40.0 m, respectively, and a depth in places where supports are placed up to 3 m. The width of the obstacle to be overcome may vary depending on the condition of the bank soil. A number of other combinations of using one or several TMM-3 sets are also possible. In special cases, TMM-3 can be used as a pier for floating engineering equipment: barges, rafts, ferries and for interfacing with the floating part from the CCI fleet. The heavy mechanized bridge TMM-3 consists of two main parts: a bridge layer, made on the basis of the KrAZ-255B vehicle, and a double-track bridge. The TMM-3 kit includes four bridge layers with bridges numbered 1-4, and bridge layer No. 4 is supplied without an intermediate support. The bridge laying machine is a KrAZ-255B vehicle without a platform, equipped with special devices that ensure mechanized installation of the bridge on an obstacle, its removal from the obstacle, fastening it in the stowed position and transportation. The steepness of the banks at the installation site of the bridge layer during bridge installation should not exceed 10°, the transverse slope of the terrain should not exceed 6°. The transverse slope is leveled with outriggers. The angles of entry to and exit from the bridge should not exceed 5-10°.

Collapsible metal bridge TMM-3, MARM, SARM, BARM, VAR and RMM-4

A collapsible metal bridge is a reliable steel metal structure with the ability to be repeatedly reinstalled and used in different places. Mobility is ensured by standardized elements, transportability of parts and manufacturability of prefabricated and disassembled operations. The Plant of Tanks and Oversized Metal Structures invites you to buy high-quality certified collapsible metal bridges at an economical price - from the manufacturer.

Application of collapsible metal bridges

The development of projects for prefabricated bridge structures of the RMM - 4 series was carried out in the first half of the 20th century, for the needs of the army. Today, improved designs are used both in the military complex and in civilian industries. The advantage of reusable bridges with reinstallation was appreciated and adopted:

• organization of bridge construction during the reconstruction of old and construction of new bridges, as a means of temporary crossing;
• units of the Ministry of Emergency Situations in conditions of floods, forest fires or rescue expeditions in hard-to-reach places;
• oil workers and gas field developers - when carrying out exploration work, constructing wells and laying main pipelines;
• enterprises in the construction, mining, forestry and other industries.

Collapsible structures solve the problems of crossing for remote residential areas, including a pedestrian version, with a width from 800 to 1600 mm. The advantage of the structure is the possibility of reliable long-term operation. But even in cases where the need is temporary, it is more economical to use mobile prefabricated metal structures.

Design elements

The main assembly units of RMM - 4 are sections: end and intermediate - in the form of steel spatial trusses made of channel and corner profile. The function of the end sections is to interface with shore supports and supports. The bridge deck of the superstructure is assembled from the intermediate sections.

The intermediate assembly part has the shape of a regular parallelepiped, consisting of rectangular lower and upper frames. The frames are assembled by welding from channel beams. In the standard version, a profile of a special series C is used. The frames are connected by vertical posts made of angle steel. The structure is strengthened by horizontal lintels and diagonally located braces and hangers, both in the plane of the frames and in the space between the posts.

The upper frame has brackets with holes for assembling sections with bolts into a structure of the required length. On the lower frame, the connecting unit is arranged in welded shaped gussets with holes for fasteners.

The design of the end section has a reinforced upper channel frame and 2 horizontal posts connected to opposite corners of the frame by angle beams. Thus, the side planes of the end section have a triangular shape. Spatial connections and reinforcements similar to the intermediate section. Side parts of the end element:

• most of them have a size and connecting nodes adapted for connection to the structure;
• beveled allows you to rest on supports.

To support the end part of the span, the collapsible bridge kit includes supports. This is a beam welded from two channels and sheet steel with mounting holes.

Heavy mechanized bridge TMM-6

Modern combat operations are characterized by high dynamism and difficult road conditions due to the large number of artificial and natural obstacles and obstacles. There is a need to overcome them, including by building or building bridges and crossings for heavy equipment (tanks, tractors, cars, etc.). Because bridge construction requires time and materials, it is often unacceptable in a rapidly changing environment.

The solution is to create mechanized bridges. An example is the TMM-6 heavy mechanized bridge developed by the Omsk Mechanical Engineering Design Bureau and produced by the Transport Engineering Plant.

TMM is designed for constructing bridge crossings over water barriers and dry land obstacles up to 100 m wide and up to 5 m deep and for passing troops, wheeled and tracked vehicles weighing up to 60 tons across them. Mechanized bridges are used both during combat operations and during evacuation measures, liquidation of consequences of accidents and natural disasters.

TMM consists of a bridge laying machine and bridge blocks. A bridge layer is an all-wheel drive off-road vehicle (8x8 wheel arrangement), on which equipment and mechanisms for transporting and installing a bridge block are installed. The mechanism drive is hydraulic, with power take-off from the main engine of the vehicle. The bridgelayer is equipped with a filter-ventilation system to protect the crew from dust when moving through radioactively contaminated areas and is equipped with modern means of communication - a radio station and an intercom.

The bridge block consists of a double-track span that folds in half and a telescopic support. The length of the opened span is 17 meters, the telescopic support is self-adjusting to a height of 2 to 5 m. The drive of the mechanisms that open and fold the span is hydraulic, from the hydraulic system of the bridge layer. Docking and undocking of the hydraulic systems of the bridge laying machine and the bridge block is automatic. The design of the bridge block and the special mechanism available on the bridge layer make it possible, if necessary, to reduce the transverse dimension (width) of the bridge block during transportation. The laying process is controlled by one person from a remote control located in the rear of the bridge laying machine, or remotely using a 30 m cable. Installation time for one bridge block is 5 minutes. The bridge is assembled by sequential installation of several bridge blocks.

Once the bridge crossing is no longer necessary, the bridge layer dismantles the bridge. The bridge blocks are transported to another place, where they are again installed on the barrier. Disassembly can be carried out both from the original and from the opposite shore of the obstacle.

Heavy mechanized bridge TMM-3M2 – Freight transport and special equipment

The international military-technical forum Army 2016, held from September 6 to 11 at the Patriot Convention and Exhibition Center near Moscow, demonstrated modern developments in the domestic defense industry. Russia's main exhibition event in the field of weapons and military equipment, and comprehensive support for the Russian army and other security forces, organized on the initiative of the Ministry of Defense of the Russian Federation, took place for the second time this year. The forum attracted the attention of a large number of visitors - over half a million people visited the event over six days. The exhibition widely demonstrated military equipment, as well as products of domestic automobile factories, manufacturers of all-terrain and special equipment.

KAMAZ showed its achievements in the development of unmanned vehicles. The capabilities of promising technology were demonstrated as part of a dynamic display program at the Alabino training ground near Moscow. The company presented the prototype of a car with an unmanned control system, which is now successfully being tested, to the public a year ago. The drone was developed jointly by KAMAZ OJSC, VIST Group OJSC and Cognitive Technologies. Its base was the serial KAMAZ-5350, on which the components necessary to test different modes of autonomous vehicle movement were installed: radars, lidar (an active optical sensor that emits laser beams towards the target while the vehicle is moving), video cameras, communication systems and on-board computers. For remote control, a mobile point has been created, with which you can control the car. On the eve of the current forum, the car was modified, received changes in the steering, power steering with a CAN bus. This project, whose goal is to create a new generation of unmanned vehicles by 2022, designed to ensure the safety of freight vehicles and traffic on intercity roads, is among the projects selected and financed by the state that correspond to the priority areas of development of the scientific and technological complex of Russia.

focused on armored vehicles. The all-wheel drive army armored vehicles of the Patrol family with an original hood-type body were of constant interest to visitors. One of the vehicles – a 2-axle – was created on the components and assemblies of the KAMAZ-4350 chassis, the other – a 3-axle – on the components and assemblies of the KAMAZ-5350 chassis. The purpose of armored vehicles is to transport personnel, cargo and install equipment when performing special tasks. The spacious interior allows for rational placement of various equipment and meets the requirements for protecting the crew and equipment from the damaging effects of small arms and explosive devices. The carrying capacity of the 4x4 armored vehicle is 1.5 tons. Towing a 5-ton trailer is provided. The KAMAZ-740.31 engine develops a power of 240 hp. With. The 6x6 model has a load capacity of up to 4 tons, plus a trailer of 8 tons. The engine on it is more powerful - a 260-horsepower KAMAZ-740.30. The vehicles use identical bodies designed for a crew of up to 10 people. Both models have a top speed of 100 km/h. They can overcome a vertical wall 0.55 m high and a ditch 0.6 m wide.

The third exhibit at the ASTEIS stand did not stand out in any way outwardly - it looked like an ordinary KAMAZ-5350 6x6 with a van body. The secret lay in the armored van body and cabin, as well as in the fuel tanks, batteries, air receivers and engine crankcase, protected from small arms fire. The machine's carrying capacity is 3.4 tons.

Mashinostroitelnaya demonstrated two-link tracked transporters DT-3PM, DT-10PM and DT-30P. In recent years, the manufacturer from Ishimbay has been actively working not only on improving production machines, but also on expanding the existing model range, thanks to which the traditional line of heavy machines has been supplemented with light models.

The DT-3PM model is the most compact option offered by the company. Its carrying capacity is 3 tons, its weight in running order is 11 tons. The cabin of the first link accommodates 5 people, the cabin of the second - 12 tons. The vehicle is equipped with a high-resource diesel engine with a capacity of 240 hp. With. The maximum speed on land reaches 50 km/h, when overcoming water obstacles - 6 km/h.

The DT-10PM all-terrain vehicle occupies an intermediate position in the model range. The vehicle's carrying capacity is 10 tons, curb weight is 23.5 tons. The cabin is designed for a crew of 5 people. The V-46-5C diesel engine produces 710 hp. With. The vehicle can reach speeds on land of up to 44 km/h, and afloat – 5 km/h.

The line is crowned by the heavy conveyor DT-30P. Its curb weight is 28 tons, and its load capacity reaches 30 tons. This model is equipped with the same engine as the DT-10PM. The cabin capacity is similar. The maximum speed of the all-terrain vehicle on land is 37 km/h, on water – 4 km/h.

Two-link tracked conveyors "Vityaz" are designed to operate in difficult climatic conditions of the Far North, Siberia and the Far East on soils with low bearing capacity (swamp, virgin snow, off-road, rugged wooded areas) at temperatures from +40 to -50°C. All-terrain vehicles have two welded sealed body-links. The first link contains the crew cabin, engine and transmission compartment and body. The second link can be made in the form of a body for transporting goods, crew or mounting technological equipment and weapons. The machines have a hydromechanical transmission with a single-stage hydrodynamic transformer, which ensures a smooth change in the transmitted torque depending on the movement resistance. The design of the rotary coupling device allows the machine links to rotate independently in horizontal, vertical and longitudinal-vertical planes. A distinctive feature of the design is the vertical and horizontal folding hydraulic cylinders located on the rotary coupling device, controlled from the driver’s seat. Horizontal folding hydraulic cylinders act as a rotating device, providing high maneuverability. Vertical folding hydraulic cylinders are both shock absorbers (ensure high smoothness when moving) and a device for forced folding of links in a vertical plane (allow you to overcome vertical walls up to 1.5 m high). The possibility of forced blocking of vertical folding hydraulic cylinders allows you to cross ditches up to 4 m wide. Rubber-metal tracks with steel crossbars provide low specific ground pressure (from 0.16 kg/cm2 to 0.3 kg/cm2, depending on the model) and high maneuverability. The independent, high-energy torsion bar suspension of the original road wheels with sponge filler creates a smooth ride.

The exhibition presented serial wheeled all-terrain vehicles TREKOL-39294D in various configurations. In addition, at a dynamic display at the Alabino training ground, TREKOL-39294D demonstrated its extraordinary capabilities for overcoming ground and water obstacles.

The three-axle all-wheel drive TRECOL-39294D is equipped with low-pressure tubeless tires. Its 8-seater lightweight, insulated body is made of fiberglass. Three doors are provided for boarding people and loading payloads. The original design of the all-terrain vehicle and wheels ensures high maneuverability in hard-to-reach areas and areas with a snow depth of more than 0.5 m; allows you to overcome water obstacles, large ravines, rubble and other obstacles. The modification with the letter “D” is equipped with a Hyundai D4BF turbocharged diesel engine with a volume of 2.476 liters and a power of 83 hp. s., characterized by a maximum torque of 196 Nm. The machine has TREKOL wheel gearboxes with disc brakes. Optionally installed: centralized wheel inflation, water-jet propulsion, winch, autonomous interior heater and other equipment. The load capacity on dense soils is 700 kg, on weak soils and afloat - 400 kg. Maximum speed on the highway is 70 km/h.

One of the all-terrain vehicles shown at the exhibition was paired with a TREKOL-8901 tilt trailer. Like the all-terrain vehicle tractor, the trailer is produced on low-pressure tires. Its load capacity is 300 kg. The trailer is able to overcome small water obstacles. The floating properties of the trailer are possible due to the displacement properties of the wheels. Note that all models of TREKOL all-terrain vehicles can act as tractors for transporting the trailer.

TMM-3 (TMM-3)

Heavy Mechanized Bridge TMM-3 (TMM-3)

TMM-3 (TMM-3) (Heavy Mechanized Bridge) is a Soviet heavy bridge created in the early 1960s and adopted by the Soviet Army in 1962.

Performance characteristics of the bridge layer TMM-3 (TMM-3)

• Crew 2 people to the bridge layer; 8 people for a set of bridge layers
• Weight of one bridge layer 20.4 t
• Powerplant: YaAZ diesel engine, 240 hp. (177 kW) at 2100 rpm
• Cruising range 750 km on highway
• Maximum transport speed 70 km/h on the highway, 40 km/h over rough terrain
• Bridge block length 10.5 m
• Bridge width 3.8 m
• Bridge load capacity 60 t
• Obstacle width up to 40 m
• Obstacle depth up to 3 m

The bridge layer or heavy mechanized bridge TMM-3 (tmm-3) is designed for mechanized construction of a bridge over obstacles up to 40 meters wide and up to 3 meters deep.

The bridge layer TMM-3 (tmm-3) was created by the Omsk Design Bureau of Transport Engineering. The heavy mechanized bridge set TMM-3 (tmm-3) consists of four bridge laying vehicles based on Kraz 255B all-wheel drive wheeled vehicles, three of which carry bridge blocks with supports and one vehicle carries a bridge block without supports. In the transport position, the axle blocks are folded in half and placed on the vehicle frame behind the cab.

TMM-3, bridge span guidance

To build a bridge, the TMM-3 (tmm-3) bridge layer approaches the obstacle in reverse and, using a cable block drive for opening the bridge or a hydraulic system, turns the bridge and places it on supports or one end on the shore. Then the next bridge layer does the same work, but from the bridge span already installed by the previous bridge layer. And so on for all four cars. The spans are connected to each other. The bridge is built without blocking the riverbed or performing bottom excavation works.

The length of one extended span of the bridge block is 10.5 meters. The bridge width is 3.8 m, the track width is 1.5 m, the load capacity is 60 tons for tracked vehicles and 11 tons per axle for wheeled vehicles.

The TMM-3 (tmm-3) bridge layer has a system for protecting the crew from dust when moving through radioactively contaminated areas and radio communication equipment.

The erection time for a single-span bridge is 11 minutes, for a two-span bridge - 30 minutes, for a three-span bridge - 56 minutes, and for a four-span bridge - 72 minutes. When building a bridge, the permissible longitudinal slope of the bridge is no more than 10°, the transverse slope is no more than 6°. For supports, the permissible slope along the bridge axis is no more than 30°, across the axis - no more than 20°. The bridge can be removed from any bank.
