Abstract
A sliding dump trailer that provides dumping, loading, and unloading functionality using mechanical manipulations. A bed frame is attached to a towing tongue using hinges, and one or more slide rails. The slide rails selectively engage and disengage with an axle frame. The bed frame is manipulated to a loading/unloading position by locking wheels on the axle frame, disengaging the axle frame from the slide rails, and pushing the tongue in a reverse direction, causing the slide rails to slide over the axle frame which, in turn, allows the bed frame to tilt over the hinges. Continuing to push the tongue in the reverse direction further tilts the bed frame to a dumping position. The bed frame is returned to a horizontal towing position by pulling the tongue in a forward direction.
Claims18
A dumping trailer, comprising:
- a bed frame attached to a towing tongue using one or more hinge mechanisms that create one or more hinge points between the bed frame and the towing tongue, the bed frame being tiltable relative to the towing tongue by means of the one or more hinge mechanisms such that in a towing position, the bed frame and the towing tongue are disposed substantially parallel one to another and in a dumping position, an angle between the bed frame and the towing tongue is tiltable up to a substantially vertical position in which wheels associated with an axle frame are lifted off a horizontal ground plane;
- one or more slide rails attached to the bed frame;
- and
- the axle frame is secured to the one or more slide rails, one or more of the axle frame or the one or more slide rails including one or more locking mechanisms that selectively engage and disengage the axle frame with the one or more slide rails, wherein when the one or more locking mechanisms are disengaged the axle frame is free to slide along the one or more slide rails.
1 more element
A dumping trailer, comprising:
- a bed frame attached to a planar towing tongue, the entire towing tongue being planar, and the entirety of the towing tongue being disposed beneath the bed frame, the towing tongue extending rearwardly under at least half a length of the bed frame, the towing tongue being attached to the bed frame using one or more hinge mechanisms that create one or more hinge points between the bed frame and the towing tongue, the one or more hinge mechanisms being disposed at or near a center of the bed frame, such that an angle between the bed frame and the towing tongue is tiltable up to a substantially vertical position in which wheels associated with an axle frame are lifted off a horizontal ground plane;
- one or more slide rails attached to the bed frame;
- and
- an axle frame secured to the one or more slide rails, one or more of the axle frame or the one or more slide rails including one or more locking mechanisms that selectively engage and disengage the axle frame with the one or more slide rails, wherein when the one or more locking mechanisms are disengaged the axle frame is free to slide along the one or more slide rails.
1 more element
A dumping trailer, comprising:
- a bed frame attached to a planar and horizontal towing tongue using one or more hinge mechanisms that create one or more hinge points between the bed frame and the towing tongue, the bed frame being tiltable relative to the towing tongue by means of the one or more hinge mechanisms;
- one or more slide rails attached to the bed frame;
- and
- an axle frame secured to the one or more slide rails, one or more of the axle frame or the one or more slide rails including one or more locking mechanisms that selectively engage and disengage the axle frame with the one or more slide rails, wherein when the one or more locking mechanisms are disengaged the axle frame is free to slide along the one or more slide rails, wherein:
- in a towing position, both the bed frame and the towing tongue are disposed in a substantially horizontal position relative to a horizontal ground plane, the bed frame being parallel to the towing tongue in the towing position, the planar towing tongue being entirely in a given horizontal plane relative to the horizontal ground plane;
- in a loading position, the bed frame is tilted to a loading angle relative to the towing tongue, the loading angle being greater than an angle between the bed frame and the towing tongue in the towing position, the bed frame adapted to engage the ground in the loading position, and where wheels associated with the axle frame remain in contact with the horizontal ground plane in the loading position;
- and
- in a dumping position, the bed frame is tilted relative to the towing tongue to a substantially vertical position at an angle that is greater than the loading angle and the axle frame and the wheels associated therewith are lifted off the horizontal ground plane in the dumping position.
