Import substitution in Galich style


Engineering technology for the armed forces attracts constant attention at exhibitions of all levels. The forum "Army-2021" was no exception, one of the important places at which was occupied by the exhibits of the Galich Truck Crane Plant. The company has been manufacturing mobile cranes since 1982 and has managed to achieve considerable success in this rather narrow specialization. In Galich, one of the few in the country has mastered their own production of 100-ton cranes on imported MZKT and Volvo chassis. For such heavy equipment, a five-axle chassis is required, which are not mass-produced in Russia. Truck cranes are also supplied to the armed forces, but in this sector the lion's share is occupied by machines from the Klintsovsky plant. The Galicians adapted to market realities and offered the military a heavy 50-ton crane KS-65713-5M on a four-axle KamAZ-6560. "Klintsy" supply the Russian army with cranes with a lifting capacity of up to 32 tons, so the heavy machine from Galich turned out to be out of competition. KS-65713-5M is handed over to the customer complete with a trailer with seven tons of counterweights. The actual monopolization of the market for army cranes by the Klintsovsky plant forces the Galicians to diversify the production range.

More recently, a universal piling unit (USA-2) was adopted in service, unified in many units with civilian cranes. Moreover, the unit, in which case, may not drive piles into the ground, but lift loads up to 32 tons. This is how the Galicians gracefully entered the fiefdom of the cranes from Klintsy. The unit drives the piles with a diesel hammer with a percussion part of 1,25 or 1,8 tons, mounted on an 18,7-meter pile-mast. By the way, the boom of the mast is made in the form of an ovoid, which complicates production, but greatly facilitates the structure without loss of strength. According to calculations, USA-2 is capable of working with piles weighing up to 5 tons and up to 12 meters long. It is not for nothing that the pile-driving unit is called universal - the kit may include a cradle of the elevator and a drilling rig.

In 2015, the truck crane plant presented to the military a completely non-core unit - a heavy mechanized bridge TMM-3M2. This is a typical example of abandoning imported equipment. For a long time he served in the Soviet and Russian armies and still serves today as TMM-3 on the basis of the Ukrainian KrAZ-255B. Six years ago, the time came for a major overhaul of a part of this fleet, and, for obvious reasons, this is impossible without changing the chassis. After the bridge was transferred to the domestic KamAZ-53501 base, the characteristics did not fundamentally change. Carrying capacity - 60 tons, link length of four bridges - 42 meters, width - 1,5 meters. Due to the fact that the plant in Galich specializes in hydraulic cranes, there are no more mechanical winches and outriggers in TMM-3M2.

Continuing the topic of import substitution, the truck crane plant in Galich at Army-2021 presented a replacement for the Kharkov regimental earth-moving machine PZM-2. The solutions used on the novelty are largely controversial.

"Shrew" PZM-2M


Formally, the PZM-2M is only a further modernization of the military tractor from Kharkov T-155K. But in fact, it is not easy to find common features between a novelty and a well-deserved car with fifty years of experience. At the same time, there are units that, after restoration, migrated from the tractor to KamAZ-65224. This is the trencher itself and the dozer blade. Transferring engineering equipment from a tractor chassis to a civilian, albeit off-road, truck was not an easy undertaking. Apparently, the design of the machine did not cope well with the increased loads during digging trenches. The KAMAZ SUV also lacked traction force, which forced the engineers to take a certain risk. For the first time in world practice, they have integrated a crawler hoist to help the shrew during work. The official name is a multifunctional tracked mover. In the development of a largely unique unit, engineers again used the unification with the existing technology. Tank the caterpillars did not fit in terms of mass-dimensional parameters, so it was decided to use spare parts from a skidder. It was possible, of course, to take the tracks from the BMP, but it was the skidders that were at hand. At first glance, a controversial decision - how to replace such typically civilian units in the army? The decision was made in favor of the truck crane plant, which has long-standing ties with skidder manufacturers. It's all about the special crawler cranes KC-59713-14T and KS-59713-32T, which are assembled in Galich on the basis of the TL-5ALM tractors manufactured by Altailesmash. It seems that the truck crane plant has no problems at all with the supply of caterpillar tracks.

The mechanics of the multifunctional tracked mover are straightforward. As soon as the unit copes with the task, the propulsion carriage on hydraulic drives is pulled up half a meter under the "belly" of KamAZ, and the PZM-2M turns into an ordinary truck in terms of maneuverability. Actually, it is precisely in the high maximum speed that the key advantage of the novelty is that in all other parameters it is in no way better than the Kharkov PZM-2. According to Alexander Trofimov, General Director of the Design Bureau for Prospective Developments of the Galich Plant, the earthmoving KamAZ is only a product of the restoration and modernization of old equipment, and not at all an innovation. The tricks with the lifting caterpillar cart were not in vain for the mass of the unit - from the initial 12,8 tons of PZM-2, it rose to 23,5 tons. As the historian of technology Yuri Pasholok rightly asks in his blog: what, then, is the benefit from modernization? Almost a twofold increase in mass, coupled with the complexity of the design, did not affect the efficiency of the earth-moving machine in any way. The possibility of remote control does not count - this newfangled gadget can now be installed on frankly outdated equipment. It's all about the army order. According to the aforementioned general director Alexander Trofimov, the military needed a vehicle that could move freely in a combined arms column. Kharkov tractors are not capable of this for constructive reasons.

The engineers of the truck crane plant suggest using the PZM-2M not only as a purely army earth-moving machine, but also for the needs of civil defense. According to the developers, the working unit is capable of creating wide mineral fire protection strips in the forests, and the earth thrown out by the rotor can also extinguish fires. However, the advertising footage shows that PZM-2M is hardly capable of extinguishing even a small forest fire. To do this, drive the machine directly to the front edge of the fire. The very stream of shattered earth flies in almost all directions, filling the cabin more than the space around it.

The development of the PZM-2M is a typical example of a sober approach to the design of equipment. Cheap and cheerful. On the one hand, this is faster, but on the other hand, it does not allow taking serious evolutionary steps. And the lifting pair of caterpillars is unlikely to be a justified technical breakthrough.

        To put on a long wheelbase a completely non-maneuverable unit, which is intended for engineering equipment of positions? What for? There is MDK, there is armored vehicle (both those and others in all variations), there is a PZM (for the regimental level), just replace the wheelbase with the same "Kirovets"

            Zhenya, good evening! I am a military engineer in the past, I have an excellent command of the topic. Acceptance of the equipment indicated by you for supply is an open failure in the engineering troops. Let's see ... The mobility of engineering troops can be provided exclusively with the use of either tracked or two-link vehicles (depending on the tasks being performed). And the suspension of the kegress unit under Kamaz, to perform the tasks of engineering support for the battle, coupled with the obsolete PZM-2G, is generally a crime ...

              Yes, some kind of strange replacement, to be honest. As I understand it, they stupidly take the working body and move it to the KAMAZ, and so that it does not get stuck in shit, they came up with a combined wheeled-caterpillar mover for it. Somehow everything is complicated, in my opinion. If it’s impossible to set up production of the T-150, then it probably could have been changed to some more suitable base, for example, a completely tracked one. The only plus I see here is that there is now a remote control via the remote control. And everything else is doubtful.

            It will reach the approximate place of work along the highway. And then? On arable land and into muddy roads? Moreover, pushing a pile of soil in front of you or trying to pull a buried working part behind you. And all this is on the black soil of Ukraine, and not on soils with good bearing capacity. And closer to the floodplain of any river?

      No, it’s easier, alas, and on KAMAZ it is out of place ... Here "Kirovets" is needed. The whole essence of PZM-1, PZM-2G lies in the conveyor of the device, namely, in the hydraulic rotary device T-155 K. It is on such a technique that competent mech.-water. is able to profile the trench without the risk of ripping off the shear fingers (PZM-1) or hammering the thrower on the PZM-2G, or even tearing the working body (there were such cases in my practice), especially on stony soils. As for the use of the proposed installation for fire-fighting purposes, I doubt that this is justified. Affected by the low productivity of the working body, the small diameter of the thrower, especially when constructing foundation pits.

    It is a very correct decision to install a crane on the basis of a skidder from Galich - this will facilitate the construction of long-term defensive structures, as a rule, there are no roads and the bearing capacity of the soil is low. For example, in the Kuril Islands, we erected tank towers, for the installation of which we needed powerful cranes and which were in a two-axle modification (their weight was more than 20 tons), and all were mercilessly "torn" and digested from moving them from place to place by couplings of heavy tractors, since they themselves cannot move on the ground, which is a viscous black "butter" (volcanic black ash), especially after rain.
    And with the PZM 2M they were really too smart.

      What are we talking about. An extremely controversial decision to make military engineering equipment on a long wheelbase with an overloaded axle load. This is the same technique that kneads the ground even more than combat. And it must work with a guarantee, even in the most difficult conditions: weather, combat, topographic. Or all together.

    PZM 2 had one drawback, it was its tractor base, if it was replaced with tracks or with a base from a T72 tank it would be very healthy, since it was this particular machine that lacked the tracked base. And so the idea of ​​making KAMAZ a base for Pantsir and the recent detonation in Syria once again shows that a tamper-free base is a serious mistake, especially since KAMAZ has one drawback, which is its high base, which can be seen from the frequent accidents of these cars on the roads

      The advantage of the PZM was the tractor 2-link base. Unlike the T-150, the T-155K transporter could develop a higher speed, while maintaining an acceptable traction load when using the working body. The features of using the PZM-ki are hidden in the technical specification for the design of this machine ... The universalization of equipment (especially engineering, and not only) without taking into account the specifics of the tasks being performed is a pitfall for the commander ... Try to use the PZM-2G for fragments of a pit in a mining woodland, in clay soils. Have you ever had a conversation with a military interrogator about the severed leg of a dunce mech-water, when he, without turning off the hydraulic drive, climbs to pierce the hammered thrower with his leg ready for amputation? It is clear that the commander's fault is present ... But how can you complete the combat mission in full? The task of the designer is not to make life easier for himself, but to do everything possible to complete the combat mission with the help of the equipment he has developed! And we install caterpillar propellers on "long gauges" with cranes, plus earth-moving equipment ... I would like to look at the authors of "this miracle" in conditions that are somehow close to combat! You look, and the installation will be taught to fly, to dive ...

    I read all the comments, and specialists, and not so much. I wonder why no one mentioned such, in my opinion, an excellent base as from GMZ? Or was it also released in Ukraine? And then they came up with a dump on KamAZ and sprinkled a caterpillar drive. Then they would have completely put it (KamAZ) on the tracks. Off-road - only caterpillars, time-tested and not only, the lower the specific pressure on the ground, the better.

    I read the comments. And I was surprised at the number of specialists-designers of three-branch starships.
    1. I don’t think there are absolutely stupid people in the organization. And in the presence of a tracked platform, they did not offer this option. But, apparently, it was rejected, but that indicates the text of the article.
    2. Separate chassis. I think everyone who was related to the engineering troops knows what TMK-2 is, and that, in fact, a separate chassis was made for it at MAZ. So - according to his father, who served in the engineering troops, during the years of his service the car was never used for its intended purpose, because it was corny that there were no spare parts for repairs, and it was elementary to replace the punctured wheel.
    Hence the conclusion that it is hardly advisable to develop a fundamentally new chassis, even on existing units.
    So this "Frankenstein monster" is a compromise, based on the test results of which a decision will be made whether it is necessary to bother so much, or it is easier to make a caterpillar unit and give it a trawl for movement "on the march."

    But I’m wondering - what kind of customer’s demand is this (at the expense of keeping up with the march)? Is it that they have there with what speeds the columns go, that the base like a wheeled tractor will not keep up? Even if it is a purely convoy, not mixed. It smacks of corruption and stretching competitive performance characteristics on the existing model.

      Kamaz can go 60.
      Most likely, objective limitations will not allow the tractor to accelerate - without a suspension, with a short wheelbase, on large wheels.

    Creeping crap, who will deal with hydraulics in such quantities?

    Add a tractor unit with a trawl to the sappers for each tracked unit and they will not lag behind everyone else.

    The caterpillar "carriages" require a horizontal thrust to transfer the force to the frame.

    Interestingly, was the option considered instead of the caterpillars 4 more of the same wheels lowered?
    I also wonder if the axle suspension switches off during operation?
    Whoever tried to plow on a UAZ knows that bridges tend to leave under the frame when loaded :)
