Harvesting apparatus with overload protection device

A harvesting apparatus (10), namely merger or pickup swather, the harvesting apparatus comprising:

• a supporting frame (12) having a longitudinal member (13) and crossmembers (14, 15, 16),
• a chassis (18) having wheels (19),
• pickup members (20) designed as a pickup for picking up harvested crop, and with transverse conveyor devices (21) designed as belt conveyors for conveying the picked-up harvested crop in a transverse conveying direction running transversely with respect to a longitudinal direction,
• wherein a respective pickup member (20) and a respective transverse conveyor device (21) are arranged on a first side and on a second side of the longitudinal member (13),
• wherein a first shiftable crossmember (14) which is arranged on the respective side of the longitudinal member (13) and accommodates the respective pickup member (20) and the respective transverse conveyor device (21) is shiftable about an axis (24) extending in a vertical height direction relative to a second shiftable crossmember (15) and is furthermore shiftable via the second shiftable crossmember (15) about an axis (25) extending in the horizontal longitudinal direction relative to a fixed crossmember (16) acting on the longitudinal member (13),
• wherein a respective first overload protection device (26) is positioned between the first and second shiftable crossmembers (14, 15) arranged on the respective side of the longitudinal member (13), the respective first overload protection device triggering when a force which acts on the respective pickup member (20) and/or the respective transverse conveyor device (21) and/or the respective first crossmember (14) in a horizontal direction counter to the harvesting direction exceeds a limit value and permitting shifting of the respective pickup member (20) and of the respective transverse conveyor device (21) about the axis (24) rearwards in the opposite direction to the harvesting direction, and
• wherein a respective second overload protection device (30) is positioned between the second shiftable crossmembers (15) arranged on the respective side of the longitudinal member (13) and the respective fixed crossmember (16), the second overload protection device triggering when a force which acts on the respective pickup member (20) and/or the respective transverse conveyor device (21) and/or the respective first and/or second crossmember (14, 15) in the vertical direction exceeds a limit value and permitting shifting of the respective pickup member (20) and of the respective transverse conveyor device (21) upwards about the axis (25) extending in a horizontal longitudinal direction.
