Applicator boom tilt frame

A tilting boom applicator comprising:

• a laterally-extending applicator boom;
• a lift supporting the applicator boom and operable to vertically shift the applicator boom,
• said lift including a first lift arm and a second lift arm extending longitudinally relative to the applicator boom;
• and
• a tilt frame interconnecting the applicator boom and lift,
• said tilt frame including a first frame section mounted to the first lift arm and a second frame section mounted to the applicator boom,
• said first and second frame sections attached to each other at a frame pivot joint that defines a longitudinal tilt axis, with the frame pivot joint permitting tilting movement of the applicator boom relative to the lift about the longitudinal tilt axis,
• said second lift arm being directly attached to the second frame section and serving to limit movement of the applicator boom relative to the lift about a lateral pitch axis while permitting the tilting movement,
• said first frame section being attached to the first lift arm and restricted from swinging relative to the first lift arm about the frame pivot joint,
• said second frame section being positioned below and hung from the first frame section,
• said first frame section including a hinge element that presents a hinge opening aligned with the longitudinal tilt axis,
• said second frame section including a hinge assembly removably attached to a remainder of the second frame section,
• said hinge assembly presenting a hinge bore, with the hinge bore and opening cooperatively receiving a pin that pivotally connects the frame sections,
• said tilt frame being devoid of any part of the first frame section below the hinge assembly.

A tilting boom applicator comprising:

• a laterally-extending applicator boom;
• a lift supporting the applicator boom and operable to vertically shift the applicator boom,
• said lift including a first lift arm and a second lift arm extending longitudinally relative to the applicator boom;
• and
• a tilt frame interconnecting the applicator boom and lift,
• said tilt frame including a first frame section mounted to the first lift arm and a second frame section mounted to the applicator boom,
• said first and second frame sections attached to each other at a frame pivot joint that defines a longitudinal tilt axis, with the frame pivot joint permitting tilting movement of the applicator boom relative to the lift about the longitudinal tilt axis,
• said second lift arm being directly attached to the second frame section and serving to limit movement of the applicator boom relative to the lift about a lateral pitch axis while permitting the tilting movement,
• said lift arms presenting fore and aft lift arm ends,
• said aft lift aim ends being pivotally mounted to the tilt frame at respective arm pivot joints,
• said lift including a base,
• said fore lift arm ends being pivotally mounted to the base at respective base pivot joints,
• said arm pivot joint of the lower lift arm comprising a ball joint that permits relative pivotal movement between the lower lift arm and tilt frame about orthogonal axes, with swinging movement of the tilt frame and lower lift arm causing movement of the applicator boom relative to the lift about the lateral pitch axis.

A tilting boom applicator comprising:

• a boom support structure;
• a laterally-extending applicator boom;
• first and second lift arms connected to the boom support structure,
• said arms cooperatively supporting the applicator boom on the support structure for relative vertical shifting;
• and
• a tilt frame,
• said tilt frame including a first frame section mounted to the first lift arm and a second frame section mounted to the applicator boom,
• said first and second frame sections attached to each other at a frame pivot joint that defines a longitudinal tilt axis, with the frame pivot joint pen titling tilting movement of the applicator boom about the longitudinal tilt axis,
• said second lift arm being directly attached to the second frame section and serving to limit movement of the applicator boom about a lateral pitch axis while permitting the tilting movement,
• said first frame section including an elongated body and a bushing assembly mounted to the elongated body, with the bushing assembly serving as a hinge element,
• said second frame section presenting another hinge element that is attached to the first-mentioned hinge element with a pin,
• said bushing assembly including a flexible bushing that receives the pin and flexes in response to off-axis loading of the pin caused by movement of the applicator boom about the lateral pitch axis.
