The KWZT Mamut (from the Polish K ołowy W óz Z abezpieczenia T echnicznego ; literally in German: wheel-driven technical recovery vehicle ) is a Polish recovery and towing vehicle based on the Czech Tatra 815-7 . It serves as a mobile workshop and has the task of repairing broken-down military wheeled vehicles or towing them away.
Development history
Since 2005, there are serious Radpanzer type KTO Rosomak in the service of the Polish Army. This makes it necessary that there should be an equivalent recovery vehicle in terms of performance. The Polish company Szczęśniak with grants from the Polish Ministry of Defense began development work for the KWZT-1 Mamut . In 2010 the public presentation took place, in the following year the evaluation by the Polish army, in which the KWZT-1 was not adopted. The KWZT-2 version was specially designed for a call for tenders from Saudi Arabia in 2015, which has a significantly reduced curb weight because certain mining technology was not installed. The current status of the procurement is not known. The version KWZT-3 was adapted to the requirements of the Czech army. A small number are in use.
technology
The KWZT Mamut is based on the chassis of the four-axle Czech military truck Tatra 815-7Z0R9T 44 440 8 × 8.1R . This vehicle was specially developed for use in extreme climatic conditions. The crew of the KWZT Mamut also offers a maintenance service and carries out simple repairs in the field. The recovery technology comprises two main winches and one auxiliary winch as well as a hydraulic crane of the type HMF8520 K2 , which can be remotely controlled from a distance of up to 60 meters. The crane from the Danish company HMF can lift 12,000 kg by 3.5 m. With a maximum extension radius of 8.4 meters, the crane can still lift 5,200 kg. The two main winches could pull a maximum of 48 tons in total, the rope length is 100 meters each. The Mamut also has a clearing blade attached to the front. It can be used as a "ground anchor" for winch work or, to a limited extent, for smaller earthworks. With the help of a towing goggle at the rear of the KWZT Mamut, wheeled vehicles with a total mass of 44 tons can be pulled, with a maximum lift of 14 tons. The KWZT-1 has welding equipment and can carry spare parts. It can also pump fuel out of the damaged vehicles and transport it to operational vehicles. The KWZT Mamut is powered by a Deutz TCV 2015 V08 diesel engine with 440 kW, which is connected to an automatic transmission. Alternatively, a Tatra diesel engine can be installed. The vehicle has a unique Tatra independent wheel suspension with oscillating semi-axles. Each wheel moves up and down independently of one another, which guarantees very good off-road mobility and higher speeds on unpaved roads. This chassis has been continuously developed and improved by Tatra. The driver's cab , which can accommodate up to five people, is armored according to the NATO standard STANAG 4569 (Level 2 / 2a, b protection) and offers protection against fire from handguns , mines and unconventional explosive devices and incendiary devices .
