Abstract
A trailer includes a tongue, an upper frame, a lower frame coupled to the upper frame via a plurality of arms, and a lift assembly. The lift assembly includes 1) a hydraulic ram and 2) a hydraulic pump that is operatively connected to the hydraulic ram. The hydraulic ram raises the upper frame to a raised position when the hydraulic ram is retracted, and lowers the upper frame to a lowered position when the hydraulic ram is extended. The lift assembly is configured to be removably attachable to a trailer for retrofit operations, lift assembly replacement, or lift assembly reuse upon trailer sale or disposal. Also included is a method of raising and lowering a vehicle.
Claims15
A trailer comprising:
- (A) an upper frame dimensioned and configured to transport a boat and launch the boat into a body of water;
- (B) a lower frame coupled to the upper fame via a plurality of arms, wherein the upper frame is located above the lower frame;
- and
- (C) a lift assembly that includes:
- (1) a hydraulic rain that includes a moving end and a stationary end that is located above the upper frame such that at least the stationary end of the hydraulic ram is positioned to remain out of the body of water when the boat is being launched;
- and
- (2) a hydraulic pump that is operatively connected to the hydraulic ram, wherein the hydraulic ram raises the upper frame to a raised position relative to the lower frame when the hydraulic ram is retracted, and lowers the upper frame to a lowered position relative to the lower frame when the hydraulic ram is extended.
A method comprising:
- (A) providing a trailer that includes
- (1) an upper frame that is dimensioned and configured to transport a boat,
- (2) a lower frame that is located below the upper frame, and
- (3) a hydraulic ram that is connected to the upper frame and that includes a stationary end;
- (B) raising the upper frame relative to the lower frame by retracting the hydraulic ram;
- (C) lowering the upper frame relative to the lower frame by extending the hydraulic ram;
- and
- (D) launching the boat into a body of water while at least the stationary end of the hydraulic ram remains out of the body of water.
