FREELY SWINGING SELF-LEVELLING SPRAY BOOM

摘要

A freely swinging self-levelling spray boom includes a support structure and a mounting adapted to mount the support structure to a vehicle to swing freely about a pivot axis lying in a direction of travel of the vehicle. A spray boom is supported by the support structure. A tank adapted to hold liquid spray medium is supported by the support structure. The tank is symmetrically mounted to the support structure relative to the pivot axis. The weight provided by the tank and the liquid spray medium it contains serves to maintain the support structure and the spray boom in a substantially horizontal orientation when the vehicle is traversing a slope and dampen oscillations of the spray boom.
