The PMM-2 ( Russian ПММ-2, паромно-мостовая машина-2 , in German: Bridge Ferry -2) is a military amphibious floating rapid bridge and transfer vehicle from Soviet production that was developed in the 1970s. It should replace the previous system PMM Wolna .
Development history
In the mid-1970s, a replacement for the translation systems PMM Wolna and GSP-55 as well as the pontoon park PMP was considered. Originally this should have been the Wolna system introduced in 1974, based on a heavy four-axle 8 × 8 truck of the type SIL-135 . The wheel chassis proved to be problematic in use, which is why the Soviet military concentrated on a chain-driven chassis again. The new system should show its advantages especially for wide water hazards of up to six kilometers. As early as the 1980s, the PMM-2 system showed considerable weaknesses, especially when it came to translating the increasingly heavier battle tanks from Soviet production. The production of the PMM-2 and the improved version PMM-2M has meanwhile been discontinued. The GZM-003 floating speed bridge is produced in the People's Republic of China and is based on the PMM-2M version.
vehicle
The PMM-2 was developed on the basis of the chain-driven swimming car PTS-2 . This is a modified version of the MT-T chassis, which uses various components of the T-64 tank. When driving, the two hinged pontoons are folded on top of each other on the vehicle. Several PMM-2s can operate coupled or individually. It is propelled in the water by means of two propellers. Every PMM-2 ferry has folding loading ramps so that loading and unloading is possible from both sides. The engine is to be a W-46-5 - multi-fuel engine that yields 38.88 liters of displacement a power output of 690 hp (507.5 kW) at 1900 rpm. The driver's cab is armored against 7.62 mm projectiles and is unarmed.
PMM-2M
In the improved version PMM-2M, the nominal load capacity of the ferry was increased by 2.5 tons in order to cope with the increasing weight of the main battle tanks of the 1970s and 1980s. The capacity reserve of the ferry was minimized by this value.
As part of the Russian military operation in Syria , the Russian army built a pontoon bridge from PMM-2M ferries across the Euphrates in September 2017 . The 210 meter long bridge near Deir ez-Zor has a capacity of up to 8,000 vehicles per day.
