Vertical folding booms

KVERNELAND used Sprays and Sprayers to roll in its new Rau range of mounted machines.

The Expert sprayers are offered with 800, 1000 and 1300-litre tank capacities with boom widths from 16m to 24m.

Boom stability, says Kverneland, is maintained by Raus Horizontal and Automatic Balancing Control Systems (HBS and ABS). The HBS system uses rear facing struts and rubber dampers to restrict boom movement, while ABS is designed to keep the boom parallel to ground contours to maintain the required nozzle height.

Specification for the Expert sprayers include piston diaphragm pumps available in 140 litre/min to 200 litre/min capacity. The tank has a dry sight gauge, low-level induction hopper and clean water and hand-wash tanks.

Also from Rau was the companys new HC series booms to fit its existing Spridomat D2 mounted and Spridotrain G trailed sprayer ranges.

A special design feature is considered to be its vertical folding action, a system which marks a departure from Raus usual horizontal folding versions.

HC booms are available in 21m and 24m versions – each with three alternative operating widths – and 18m and 27m sizes are under development. Price for a Spridomat D2 sprayer with a 1000 litre tank and 21m boom is £14,750, while the Expert sprayers cost from £10,555. &#42

Vertical rather than horizontal folding is the forté for Raus latest HC series booms.
