Zetor Gerlach is a new-generation armoured tactical vehicle (ATV) developed by Zetor Engineering Slovakia.
Zetor presented the Gerlach 4×4 combat version at the International Defence and Security Technologies Fair (IDET) 2019 in Brno, Czech Republic, on May 2019.
The company agreed with Rheinmetall Protection Systems to equip its Gerlach ATV with advanced ballistic and anti-mine protection systems supplied by Rheinmetall, in September 2019.
Zetor Gerlach design details
The 4×4 is based on a chassis known as Rolling Chassis Zetor. It uses multi-layer components, which increase the protection of the occupants and the vehicle. The overpressure armoured capsule is directly mounted on the chassis, while the gantry frame arrangement can resist high dynamic effects.
The ATV measures 5.65m-long, 2.5m-wide and 2.5m-high. It has a conventional layout, housing power-pack at the front, crew cab in the centre and a cargo section at the rear. The forward crew cab receives protection from a two-piece windshield. Two doors are fitted on either side of the hull for occupant entry and exit.
Its cabin offers a maximum internal space of 7.7m³, which can accommodate up to six personnel including crew and troops. Noise suppression and anti-vibration materials make up the interior. The vehicle also has a large cargo space, which can accommodate combat gear, armaments or equipment weighing up to 1.5t.
The modular vehicle can be reconfigured into three versions to meet different mission requirements. The base version, with a standard weight of 12t, can house four occupants, while the remaining two versions can transport five and six personnel, respectively.
The Zetor Gerlach is fitted with an air conditioning system and a chemical, biological and nuclear (CBN) protection system. The vehicle also integrates data and voice communication systems.
Armament and self-protection
The combat version of the Zetor Gerlach is armed with a remote-controlled weapon system (RCWS) mounting a machine gun. The roof can also be installed with different types of manned or remote-controlled machine gun turrets, anti-tank guided missile (ATGM) launchers, mortars or grenade launchers.
The vehicle offers Nato STANAG 4569 Level 3 ballistic protection and Nato STANAG 4569 Level 3a and 3b anti-mine protection.
The double bottom hull with anti-mine “V” shield ensures superior protection against mines and improvised explosive devices (IEDs). The ATV can survive an anti-tank explosion of up to 8kg of TNT under the axle and the cabin.
The ATV is offered with different levels of ballistic and anti-mine protection, according to customer requirements.
Zetor Gerlach engine details
The vehicle is equipped with an MTU six-cylinder engine with a rated power output of 240kW and a maximum torque of 1,300Nm, while the engine is coupled to a six-speed automatic transmission for providing maximum power at different speeds.
The Gerlach 4×4 vehicle has a power-to-weight ratio of 17.1kW / t. The independently suspended sprung axle system is driven by a pair of drive shafts through a downward transmission supplied by GHM.
The Zetor Gerlach vehicle can attain a maximum road speed of 110km / h and a maximum cruising range of 800km.
It can cross a maximum vertical step of 0.5m and trenches with a maximum width of 1m. It can negotiate terrain grades of up to 70% and side slopes up to 40% when carrying the full load. It can wade a maximum depth of 1.2m without preparation.
The ATV is also fitted with a central tire inflation system (CTIS) to offer high mobility on different terrains.
