A support structure is provided including elevated front and rear support portions from which a pair of depending tension members are supported. An elongated horizontal lift member is supported at its opposite ends from the lower ends of the tension members and motor structure is provided and operatively connected between the support structure and tension members for selectively elevating and lowering the lower ends of the tension members relative to the support structure support portions and thereby elevating and lowering the lift member. The lift member is adapted to rest upon a horizontal support surface and to have the front and rear wheels on one side of a side dumping wagon rolled thereonto and thereoff when the lift member is disposed at least substantially at the level of the support surface. In this manner, the side of a side dumping wagon remote from the side thereof to which the discharge chute of the wagon opens may be elevated relative to the discharge chute side of the wagon in order to enable the side dumping wagon to be more quickly and completely emptied through the side discharge chute thereof.
A side lift for side dumping wagons of the type including opposite side front and rear wheels, said lift including upstanding support means having a pair of horizontally spaced elevated support portions, a pair of depending flexible tension members freely dependingly supported from said support portions and disposed in an upstanding plane spaced horizontally outwardly from one side of the lower end portion of said support means, an elongated horizontal lift member spaced horizontally outwardly from said one side of said support means, the lower ends of said tension members being anchored to opposite end portions of said lift member for support thereof solely from said tension members, force means connected between said support means and said tension members for selectively and equally elevating and lowering the lower ends of said tension members relative to said support portions, said lift member being adapted to have the adjacent side front and rear wheels of a side dumping wagon spaced outwardly of said one side of said support means roll thereonto from one end thereof and thereoff from the other end thereof when said lift member is disposed at least substantially at ground level.
A side lift for side dumping wagons of the type including opposite side front and rear wheels, said lift including upstanding support means having a pair of horizontally spaced elevated support portions, a pair of depending tension members supported from said support portions and disposed in an upstanding plane spaced horizontally outwardly from one side of the lower end portion of said support means, an elongated horizontal lift member spaced horizontally outwardly from said one side of said support means, at least the lower ends of said tension members being flexible and anchored to opposite end portions of said lift member, force means connected between said support means and said tension members for selectively and equally elevating and lowering the lower ends of said tension members relative to said support portions, said lift member being adapted to have the adjacent side front and rear wheels of a side dumping wagon spaced outwardly of said one side of said support means roll thereonto and thereoff when said lift member is disposed at least substantially at ground level, a pair of opposite end anchor portions projecting horizontally outwardly from the side of said lift member adjacent said support means, and elongated tension springs anchored at one pair of corresponding ends to the outer ends of said outwardly projecting anchor portions and at the other pair of corresponding ends to said tension member lower ends at points spaced above said lift member.
A side lift for side dumping wagons of the type including opposite side front and rear wheels, said lift including upstanding support means having a pair of horizontally spaced elevated support portions, a pair of depending tension members supported from said support portions and disposed in an upstanding plane spaced horizontally outwardly from one side of the lower end portion of said support means, an elongated horizontal lift member spaced horizontally outwardly from said one side of said support means, at least the lower ends of said tension members being flexible and anchored to opposite end portions of said lift member, force means connected between said support means and said tension members for selectively and equally elevating and lowering the lower ends of said tension members relative to said support portions, said lift member being adapted to have the adjacent side front and rear wheels of a side dumping wagon spaced outwardly of said one side of said support means roll thereonto and thereoff when said lift member is disposed at least substantially at ground level, said support means comprising a pair of horizontally spaced uprights, said lift member extending along a path extending between and disposed outwardly of corresponding sides of said uprights, said lift member including a pair of opposite end horizontally transversely outwardly projecting portions, and elongated tension springs anchored at one pair of corresponding ends to the outer ends of said outwardly projecting portions and at the other pair of corresponding ends to said tension members at points spaced closely above said lift member.
