Trailer FB90-2WD

FTG forestry trailer FB90 has a loading capacity of 9 000 kg and a permissible total weight of 11 500 kg. FB90 is a forestry trailer with a crane range from 5.1 m to 7.5 m of reach.

The forestry trailer FB90-2WD has the same standard specifications as a model FB90, but it is equipped with an auxiliary wheel drive system (2WD). Driven axle system consists of 2 Black Bruin hub-motors, hydraulic & electronic control units. Black Bruin puts its high torque just where it’s needed – under the load, while more traction power is generated just when it is needed with a simple push of a button thanks to innovative electronic control and protection system.

Wheel hub drive system (WD) is designed as an aid for driving in the forest and on difficult terrain. The system consists of 2 hub motors and a hydraulic/electric control unit. The wheel hub drive system can be driven by the tractor hydraulic system or the on-board hydraulic system of the forwarding trailer. The maximum efficiency of the drive system is achieved at 300 bar pressure, therefore only the forage wagons with a built-in on-board hydraulic system can drive most effectively.

When advanced traction is not required, hub-motors are triggered to freewheeling mode – drive at high speed (up to 40km/h) fluently without any hydraulic losses and benefit from fuel savings! Motors have extra protection seals against extreme off-road conditions, such as water, dust, and dirt.

Electronic control unit (ECU) ensures effective wheel drive system control and protection – it allows to trigger drive direction and automatically turn-off wheel drive (hub motors) if the trailer would be towed too fast due to incorrect gearshift engaged – i.e. there will be insufficient oil flow generated by tractors or on-board pump with respect to engines’ RPM for hub motors to run a trailer at some particular speed. This way ECU protects hub-motors from being damaged.

Trailer FB90-2WD with an auxiliary wheel drive system is equipped with “Black Bruin” B240 hydraulic stubmotors. 2-wheel hub drive is designed on the rear axle for optimum traction. The freewheeling mode features no heating or energy loss problems.
