Abstract

A trailer is provided for removing a boat lift from a body of water. The trailer has a trailer body with a stationary axle at one end thereof. A lifting surface is movably positioned relative to the trailer body and is movable upwardly therefrom with a scissor lift. A pivoting axle assembly is provided on the trailer body so as to lift the wheels of the stationary axle to allow for the trailer to be moved within the boat lift. When the wheels of the stationary axle are lowered by raising the pivoting axle assembly, the lifting surface can then be moved upwardly so as to contact and lift the boat lift out of the body of water.

Claims (52)

1. An apparatus for removing a boat lift from a body of water, the apparatus comprising:

a trailer body having a stationary axle adjacent a first end thereof and a trailer jack adjacent a second end thereof, said stationary axle having wheels connected thereto;

a lifting surface movably positioned relative to said trailer body, said lifting surface comprising a frame structure having a pair of lifting arms, each of said lifting arms having a first end which curves downwardly in a direction towards the surface therebelow;

a lifting means affixed to said trailer body and to said lifting surface, said lifting means for lifting said lifting surface from a first position adjacent said trailer body to a second position away from said trailer body; and

a pivoting axle assembly affixed to said trailer body between said first end and said second end, said pivoting axle assembly having at least one wheel thereon, said pivoting axle assembly movable from a first position wherein the wheel of said pivoting axle assembly is positioned above a surface therebelow to a second position wherein the wheel of said pivoting axle assembly is positioned on the surface therebelow, said wheels of said stationary axle of said trailer body being above the surface therebelow when said pivoting axle assembly is in said second position.

2. The apparatus of claim 1 , said lifting means comprising a scissor lift.

3. The apparatus of claim 1 , each of said lifting arms having a bumper at a second end thereof opposite said first end.

4. The apparatus of claim 1 , further comprising;

a control panel mounted adjacent said second end of said trailer body, said control panel suitable for selectively operating said lifting means and said pivoting axle assembly.

5. The apparatus of claim 4 , further comprising:

a remote control in communication with said control panel.

6. The apparatus of claim 1 , further comprising:

at least one hydraulic pump for operating at least one of said lifting means and said pivoting axle assembly.

7. An apparatus for removing a boat lift from a body of water, the apparatus comprising:

a trailer body having a stationary axle adjacent a first end thereof and a trailer jack adjacent a second end thereof, said stationary axle having wheels connected thereto;

a lifting surface movably positioned relative to said trailer body;

a lifting means affixed to said trailer body and to said lifting surface, said lifting means for lifting said lifting surface from a first position adjacent said trailer body to a second position away from said trailer body; and

a pivoting axle assembly affixed to said trailer body between said first end and said second end, said pivoting axle assembly comprising:

an axle having wheels at opposing ends thereof;

a pivoting member affixed to said axle at one end thereof and to said trailer body at an opposite end thereof; and

an actuator affixed to said axle at one end thereof and to said trailer body at an opposite end thereof, said pivoting axle assembly movable from a first position wherein said wheels of said pivoting axle assembly are positioned above a surface therebelow to a second position wherein said wheels of said pivoting axle assembly are positioned on the surface therebelow, said wheels of said stationary axle of said trailer body being above the surface therebelow when said pivoting axle assembly is in said second position.

8. The apparatus of claim 7 , further comprising:

a hydraulic pump operatively connected to said actuator, said actuator comprising a hydraulic cylinder.

9. A trailer apparatus for removing a boat lift from a body of water, the trailer apparatus comprising:

a body having wheels adjacent a first end thereof and a trailer jack adjacent a second end thereof;

a lifting frame positioned above said trailer body, said lifting frame having a first lifting arm and a second lifting arm;

a scissor lift affixed to said body and to said lifting frame, said scissor lift movable from a first position wherein said lifting frame is positioned adjacent said body to a second position wherein said lifting frame is positioned upwardly away from said body; and

a pivoting axle assembly affixed to said body between said wheels and said trailer jack, said pivoting axle assembly having at least one wheel thereon, said pivoting axle assembly movable from a first position wherein said wheel of said pivoting axle assembly is positioned above an underlying surface below to a second position wherein said wheel of said pivoting axle assembly is positioned on the underlying surface, said wheels of said stationary axle of said body being above the underlying surface when said pivoting axle assembly is in said second position.

10. The trailer apparatus of claim 9 , each of said first lifting arms having a bumper on an end thereof, each of said lifting arms having a curved end at an opposite end thereof.

11. The trailer apparatus of claim 9 , said pivoting axle assembly comprising:

an axle having wheels at opposing ends thereof;

a pivoting member affixed to said axle at one end thereof and to said body at an opposite end thereof; and

a hydraulic cylinder affixed to said axle at one end thereof and to said body at an opposite end thereof.

12. The trailer apparatus of claim 11 , further comprising:

a first hydraulic pump operatively connected to said lifting frame; and

a second hydraulic pump operatively connected to said pivoting axle assembly.

13. The trailer apparatus of claim 12 , further comprising:

a control panel mounted on said body adjacent said trailer jack, said control panel suitable for selectively operating said first hydraulic pump and said second hydraulic pump.

14. The trailer apparatus of claim 13 , further comprising:

a remote control in communication with said control panel.

15. The trailer apparatus of claim 9 , the top surfaces of said first lifting arm and said second lifting arm defining a lifting surface.

16. A method of removing a boat lift from a body of water, the boat lift having upper and lower horizontal members and vertical post members, the method comprising the steps of:

providing a trailer having a body with wheels thereon, the trailer having a lifting surface vertically movable from a first position adjacent the body to a second position away from the body, the trailer having a pivoting axle assembly with wheels thereon, the pivoting axle assembly movable from a first position adjacent the body to a second position wherein the wheels of the pivoting axle assembly contact an underlying surface;

moving the trailer to a position adjacent the boat lift;

lowering the pivoting axle assembly from the first position to the second position so as to cause the wheels of the pivoting axle assembly to contact the underlying surface and also to cause the wheels of the trailer body to be positioned off the underlying surface a suitable distance so as to clear the lower horizontal members of the boat lift;

moving the trailer such that the lifting surface is within the vertical post members of the boat lift;

raising the pivoting axle assembly from the second position to the first position; and

raising the lifting surface so as to contact the bottom sides of the horizontal members and to lift the boat lift upwardly.

17. The method of claim 16 , further comprising the step of:

moving the trailer forward so as to remove the boat lift from the body of water.

18. The method of claim 16 , further comprising the step of:

remotely controlling the operation of the pivoting axle assembly and the movement of the lifting surface.
