TATRA Press Release / August 20, 2015

TATRA TRUCKS has completed production and shipment of the longest and heaviest TATRA truck ever. The truck has been specially engineered to accommodate a drilling rig from German manufacturer Streicher Group and will be used for exploratory drilling in difficult terrain. Gross vehicle weight of the completed vehicle is approximately 84 metric tons (185,188 lb).

TATRA TRUCKS, a manufacturer of standard trucks, vocational and specialty vehicles, fire apparatus and military tactical trucks.

In recent years, the truckmaker has seen a rising demand for the custom truck chassis that it develops and manufactures for special applications such as drilling rigs.

The chassis has eight axles and is configured for 16x8 drive according to customer requirements. The powertrain arrangement allows the driver to engage all axles, which with differential locks engaged, results in a 16x16 capability.

The forward three axles are steered, air-suspended and have a 10 metric ton (22,046 lb) capacity.

The two middle axles are rated at 16 metric tons (35,274 lb) and feature an air-leaf suspension.

The rear three axles are again steered, air-suspended and have a 10 metric ton (22,046 lb) capacity.

The rear axles steering via a VSE-supplied Electronic Truck Steering System (ETS) (http://www.bigmacktrucks.com/index.php?/topic/36853-vse-the-suspension-and-steering-systems-of-tomorrow-available-today/?hl=vse).

All steered axles are fitted with 385/65R22.5 tires while the middle tandem axles are fitted with size 315/80R22.5. In this configuration, the total weight technically allowed is 86.4 metric tons (190,479 lb), respectively up to 92 metric tons (202,825 lb) with higher capacity tires.

The powertrain that sets the new 16x16 TATRA into motion is the 32-liter 12-cylinder Caterpillar C-32 rated at 1,132 horsepower and 5,143 N.m of torque. The engine is paired with a 6-speed Allison 8610 MR automatic transmission with retarder.

Power from the Allison transmission is fed to an auxiliary gearbox which can distribute full power to the drilling rig via an upper output, or drive the vehicle via a lower output at reduced engine power.

The lower output is driveline connected to a transfer case from which drive power is distributed to the permanently driven 1st, 2nd, 4th and 5th driver axles.

Both auxiliary transmissions are proprietary TATRA units produced in-house, and are available on the TATRA FORCE and TATRA PHOENIX series.

A hydraulically-driven ventilation system located on both sides of the cab provides for the engine cooling system, transmission and hydraulic circuits.

A standard TATRA FORCE cab is used, mounted 200mm forward and 50mm lower than the standard configuration to meet customer height requirements.

The overall length of the vehicle, including frame, is 18,080 mm, height is 2490 mm and width 3000 mm. Turning radius is 15.5 meters.
