The third and last component of the hinge assembly is the boom folding apparatus. The folding apparatus is used to fold the outer boom against the inner boom for transport and storage purposes. This is accomplished by the use of two hydraulic cylinders, one on each the inner and outer booms, that are attached to the boom hinge.

Abstract: Mobile fluid delivery systems and methods are disclosed. The disclosed embodiments are particularly useful for spraying herbicides on a roadside shoulder. The systems include nozzles mounted upon a movable arm extending from a vehicle. A sensor mounted upon the vehicle detects objects which the extended arm is approaching, such as telephone or other utility poles on the side of the road. The sensor signals a control unit, which directs retraction of the movable arm to avoid collision with the object, and extension of the arm after passing the object. In targeted fluid delivery, the control unit can direct forward fluid spray to the backside of the object as the extended arm approaches, lateral fluid spray as the arm passes the object, and rearward fluid spray to the front side of the object as the arm is extended after passing the object. The system can thus effectively douse the ground surrounding a utility pole, for example, with herbicide and reduce fire hazard.

A safety breakaway mechanism is incorporated into the system for enabling the arm to deflect when struck by an undetected obstacle.

The folded boom is then pivoted about a vertical axis at the mast to lie along side the side of the tractor. The tip portion includes a parallel cable in advance of the tip portion for impacting an obstacle with the cable actuating release of the latch and accelerating the tip portion away from the obstacle to prevent impact with the obstacle.

Abstract: An apparatus for controlling the relative positioning of two hingedly connected implement portions movable between deployed or working and folded or stowed positions relative to one another includes a strut like component connected between the two implement portions and in the form of an hydraulic damper or shock absorber which is extensible and retractable in damped fashion.
