Based on the results of the tender procedures of the General Directorate of the Fire Rescue Service of the Czech Republic (DG Fire Rescue Service of the Czech Republic) announced in April and May this year, Tatra Trucks will produce up to 232 truck-mounted firefighting units in the coming years in cooperation with the manufacturers of special bodies THT Polička and KOBIT-THZ. The framework agreement provides for the delivery of up to 100 CAS 20, 45 CAS 30 and 87 CAS 30 large volume firefighting vehicles, including optional firefighting accessories and communication equipment. The vehicles will be intended for both professional and volunteer firefighting units.
At the end of August this year, the General Directorate of the Fire Brigade of the Czech Republic concluded two framework agreements with THT Polička for the supply of up to 100 tanker trucks with the designation CAS 20/4000/240 - S2R with an estimated volume of performance of CZK 867,605,455 excluding VAT and 45 tanker trucks with the designation CAS 30/8500/510 - S2R with an estimated volume of performance of CZK 388,267,377 excluding VAT. In the same period, the DG Fire Brigade of the Czech Republic concluded a framework agreement for the supply of up to 87 tanker syringes for large-volume firefighting CAS 30/9000/540 - S3VH with the company KOBIT-THZ with an estimated volume of performance of CZK 918,170,580 excluding VAT.
Both companies will be in charge of the production of purpose-built bodies and finishing of the vehicles, Tatra Trucks will produce as a subcontractor the Tatra Force T815-75RA3T latest third-generation double-axle chassis for CAS 20, Tatra Terra T815-2T5RB3 tri-axle chassis for CAS 30 and Tatra Force T815-7T5R31 second-generation tri-axle chassis for CAS 30 for high-volume firefighting. The CAS 20 tankers will be equipped with Tatra's new six-seat, four-door cab with air conditioning and independent heating and new features for increased crew safety. The CAS 30 vehicles will get the proven long four-door Terra series cab, also with a six-seat capacity, with similar equipment to CAS 20. The CAS 30 high-volume sprayers will have two-door cabs with a four-seat crew capacity, again with air conditioning, independent heating, and central locking.
The firefighting specials will be equipped with automatic transmissions with hydrodynamic converters, which will ensure greater crew safety when driving to the rescue, as well as disc brakes on the wheels of all axles. The maximum speed will be limited to the design speed of the vehicles. The purpose-built superstructures made of light metal alloy profiles will be manufactured using prismatic bolted joints and bonding technology. In addition to the special firefighting equipment, they will contain extinguishing agent tanks. In the case of CAS 20, they will hold 4,000 litres of water and 240 litres of foam; in CAS 30, they will hold 8,500 litres of water and 510 litres of foam; and the capacity of CAS 30 for high-volume extinguishing will be 9,000 litres of water and 540 litres of foam. The wiring and fuel and air distribution systems on the chassis will be protected against the effects of radiant heat from fires.
