The WZT-4 (from the Polish W óz Z abezpieczenia T echnicznego ; in German Bergepanzer ) is a Polish armored recovery vehicle based on the chassis of the PT-91 or the later version PT-91M. It serves as a mobile workshop and has the task of repairing or towing the broken down armored vehicles of the armored units.
Development history
The WZT-4 is the result of a project by the research institute OBRUM and Bumar Łabędy , which was designed as part of the export of the PT-91M battle tank to Malaysia . With the WZT-4, all components should come from the PT-91, which is why a delivery of the WZT-3 based on the T-72M was not an option. In addition to the more powerful mining technology , the changes essentially included the use of the PZL Wola S-1000R engine with 1000 hp and the SESM Renk ESM-350M automatic transmission . The first vehicle was completed in 2008 and was first presented to the public at the MSPO 2008 armaments fair. A total of six vehicles are in use with the Malaysian armed forces.
technology
The heart of the WZT-4 is its recovery equipment. These include the crane arm, the clearing and support shield and the recovery and winch equipment. A cylindrical shaft, placed on the commander's hatch, makes it deep-wading and submersible. The crane arm is installed on the front right of the chassis and enables a working range of 360 °. The maximum hook load in the supported state and with a maximum increase of 72.5 ° is 20 tons. The clearing and support shield in the armored recovery variant primarily serves as a support in crane operation and as a ground anchor during recovery work. The 3.605 m wide blade is operated by two hydraulic cylinders. The manufacturer specifies the maximum digging depth as 0.225 m. The pulling and main drum winch produces a pulling force of 300 kN in a single pull and 900 kN when using a pulley block. The tank is equipped with NBC protection and automatic fire extinguishing systems. The armament includes a roof-mounted 12.7 mm WKM-M2 machine gun made in the USA for self-defense against ground and air targets. A smoke throw system with a total of twelve 902A throwing cups (eight on the right and four on the left front side) enables the crew to evade the eyes of the enemy during battle. The vehicle is equipped with an integrated navigation system, both with an inertial navigation system (INS) and with a global positioning system (GPS) and a "battlefield management system".
