A solid base is formed by a robust frame constructed out of quality steel ST52, the booms are constructed from ST52. The frame can withstand the harsh environment on land and at high transport speeds with a full tank of 7800 liter. The minimized gravity ensures good stability. All fasteners are made of stainless steel or have a special phosphor treatment to control corrosion. The CHD sprayers are fully resistant to the corrosive effect of for example liquid fertilize.
