TR4 Boom on HARDI Navigator

Not like any other boom

TR4 stands for 4 cords in the main wing; two at the top and two at the bottom. The two bottom cords and the webbing between is actually one continuous aluminium extrusion.

The TR4 is a bi-fold boom available in 24, 28, and 30m widths. With the outer wing folded, the boom width is reduced to 15m (no breakaway at 15m).

The breakaways are tri-directional which means they can move back and forth, and up.

Smooth ride

Wing tilts are standard and equipped with nitrogen accumulation for smooth ride and performance.

Yaw forces are absorbed through patented nitrogen accumulator ‘Yaw Dampening Plunge Cylinder’ in the end of the fold cylinders.

Yaw movement is arrested through nitrogen accumulation which absorbs the energy from the boom when braking, acceleration, and steering
