Spray boom suspension device for product e.g. fertilizer, sprayer, has spacers maintaining parallely chassis and frame of boom, and forming isostatic connection between chassis and frame, and shock absorber device connected to two spacers

摘要

The device has two connecting rods (9) suspending a spray boom (2) to a chassis (3). Lateral arms of the boom are connected on a central frame of the boom. Spacers (11, 12, 13) maintain parallely the chassis and the frame, and form an isostatic connection between the chassis and frame. The spacer (11) is arranged in a horizontal plane different from a plane of the spacers (12, 13) to which a shock absorber device (20) is connected. An independent claim is also included for a product sprayer having a suspension device.
