EXTREMV All-terrain tracked vehicle for use in disaster relief and rescue operations fire, earthquake, tsunami and nuclear disasters

The EXTEMV is a civilian all-terrain tracked vehicle developed by ST Engineering, designed for civilian disaster relief and rescue operations: from the most effective and fastest possible emergency rescue, through medical evacuation, to logistical transport and firefighting. With our many years of experience in the field of special vehicle construction, we are jointly able to meet customer requirements in a tailor-made manner. In combination with our roll-off containers, which are adapted to the purpose of use, any kind of superstructure can be flexibly transported to the site of operation with the EXTREMV.

Combined with the robust drive system, the vehicle offers excellent traction, enabling it to maneuver steep gradients and obstacles, outstanding mobility on soft ground, uneven terrain and rugged hazards due to optimised running gear system and rubber tracks. The EXTREMV is thus optimally equipped for worldwide use in a wide range of climatic and topographical conditions, such as the Sahara Desert, snow in the Arctic and mountainous terrain.

    With individual concepts, customer wishes are also flexibly catered for here. The compact vehicle consisting of front cabin and chassis can transport from 4 up to 14 persons. With the lowest possible permissible maximum weight of around 11,000 kg, it has a very low nominal ground pressure of approx. 200g/cm² and reaches up to 60km/h with a range of 300km off-road and for carrying various roll-off containers (RO) with a payload of up to 3,500 kg.

    The EXTREMV has an operating temperature range of -30 to +46°C and is equipped with air conditioning (both heating and cooling) for all possible climatic conditions. In addition, it is possible to drive through water up to a depth of 1m or completely as an amphibious vehicle. The vehicle can be operated in both summer and winter conditions.
