Wheel installation crane for combines

摘要

An apparatus for removing and storing outer wheel assemblies from combines being transported on public roads is disclosed. The apparatus includes a pivoting dual-boom crane temporarily mounted to an attachment frame of a combine. The crane swings over either outside wheel assembly and provides a lifting support for installing or removing the wheel assembly. A dual-boom crane includes a wheel bar configured to grip and lift a wheel assembly. The wheel assemblies are then secured on the apparatus such that the combine can be transported over public roadways without exceeding a typical width limit.

主权项

1. A wheel installation crane, comprising:
a mounting frame assembly configured to vertically attach to an existing combine, said mounting frame assembly having a first wheel support member and a second wheel support member that both horizontally protrude from the lower part of the mounting frame assembly, said mounting frame assembly further including a first extension that extends horizontally from said first wheel support member, a second extension that extends horizontally from said second wheel support member, and a wheel support bar that extends between the distal ends of said first extension and said second extension; a boom pivot member rigidly attached to said mounting frame assembly; an elongated first boom having a first boom pivot at one end and a rotatable boom joint assembly at the other end, said first boom connected to said boom pivot member via said first boom pivot; an elongated second boom connected to said boom joint assembly at one end; a wheel lifting bar operatively attached to an end of said second boom; an upper boom pivot member rigidly attached to said mounting frame assembly; and, a first boom saddle rigidly attached to a first side of said mounting frame assembly; wherein said first boom pivot rotates within said upper boom pivot member; wherein said first boom pivot is retained by said upper boom pivot member and said boom pivot member; wherein said first boom saddle is located and dimensioned to receive said first boom when said first boom maximally pivots in a first direction; and, wherein said first boom and said second boom can rotate and pivot to bring said wheel lifting bar into position to remove a wheel from said combine.
