Obrum KWZT-1 Mamut

     Notes: A heavy recovery truck, the Mamut is one of the most capable recovery vehicles in its class. It is based on the chassis of the T-815-7 8x8 heavy truck.  It was first shown at an international arms show in 2010 and entered testing in 2011.  It entered service with the Polish Army in 2016. The Mamut was specifically designed to operate in extreme climates, including cold, heat, humidity, mud, trenches, desert, and other such bad conditions.  It is means to recover light and medium armored vehicles as well as other wheeled vehicles, and with effort, can recover some lighter tanks.  Though it currently serves only the Polish Army, it is being heavily shopped around to the world market.

     The truck is a cabover design with large windows to the front and sides with armored shutters.  Behind the cab, on either side of the crane, is the actuating and functioning equipment for the crane, the crane itself, and the NBC overpressure system, air conditioner, and heater. There is also a tunnel to access the rear of the vehicle without going out into enemy fire or an NBC environment.  Commander is on the right side of the cab, and has an overhead hatch with a pintle-mounted weapon.  The driver is on the right, and two more crewmembers are in the rear of the cab. The crewmembers have 4-way day/night CCTV cameras. The vehicle has a GPS and BMS.

     The crane is folding into the vehicle, and has a capacity of 13.5-ton capacity, or 12 tons at 3.5 meters, or 5.2 tons at 5 meters.  It can be operated remotely from the cab or by a controller from up to 60 meters away. The crane may operate in an arc of 280 degrees to either side. The Mamut has two winches, one in the front and in the back; these have a 28-ton capacity, or double that with block and tackle.  Each winch has 100 meters of cable.  The rear of the Mamut has a towing device that is capable of lifting 13.5 meters; it can also be used as a jack.  Tools carried include an air compressor, a welding set, a hand circular cutter, a “jaws of life,” all forms of basic tool sets, a large breaker bar, a torque wrench, and two sets of excavating tools. It also has a fuel pump, for pumping fuel from external sources into itself or other vehicles.  The Mamut has a frontal dozer blade, primarily for bracing the vehicle when using the crane or rear jack.

     The suspension is unique to the Tatra T-815.  Each wheel has independent suspension, and moves with terrain separately.  The engine is the T-815 standard Deutz TCV 2015 V08 turbocharged diesel, developing 585 horsepower, with an automatic transmission. Tires have a central inflation system, and are run-flat.

SMT-1

     Notes: Based on the chassis of Star 660 M1 or Star 680 M2 6x6 trucks (both about the same size and general layout), the SMT-1 generally operates in units of five vehicles, one carrying trestles.  (The stats below are for one vehicle, however.) The rear of the truck is for the most part little more than a rear frame with attachment points for the bridge section and the deployment machinery for it. The bridge section carried is based on the Russian TMM, but is considerably lighter due to construction of high-strength aluminum and a grid-based roadway.  The section is also only 3 meters wide, so some vehicles may just barely fit on it.  Each section is 11 meters long and one, two, three, or four may be used at once.  Trestles for this bridge are adjustable from 1 meter to 3.5 meters, and the truck carrying them generally carries four. 3-5 minutes are required to set each span, including setting trestles. It is a lot of manual labor.

     The crew sits in a three-man abbreviated cab; the ceiling is low enough that helmets cannot be worn in it, even though the trucks are both almost completely cabover vehicles. In front of this is the engine hood, though the entire vehicle's cab must be pulled over to access the powerpack.  The engines are Star 359M diesels developing 147 horsepower.  They are old trucks that basically have little other tactical use.
