A trailer for raising and lowering a load including a lifting frame and a base frame configured to secure the load, where a rearward portion of the base frame is rotatably connected at a rear hinge point to the lifting frame. The base frame and the load are raised and lowered based on the tension of a cable attached at one end to the base frame. The tension of the cable is adjusted by a winch attached to the lifting frame. The trailer is configured to allow for an individual operator to raise and lower the load without requiring the assistance of other personnel or facilities.

Utilities (e.g., apparatuses, systems, methods, etc.) for use in loading power equipment such as log splitting apparatuses onto cargo trailers or the like in manners that increase the number of assembled log splitting apparatuses that can be loaded onto the cargo trailers (or otherwise result in more efficient loading of assembled log splitting apparatuses onto the cargo trailers) while facilitating assembled presentation of the log splitting apparatuses after unloading from the cargo trailer.

A casino mentality hog trap assembly is built into a trailer having a frame supported by a plurality of wheels, a hitch for attaching to a towing vehicle, and a platform. A hinged trap floor is located in the platform and is moveable between a horizontal closed position and a downwardly inclined open position for causing animals to fall into a holding pen. A plurality of feeder stations are positioned adjacent to the trap floor. The feeder stations each have feeder lids that can be raised by animals to access feed contained in feeder troughs. A trigger mechanism is arranged to be tripped when two of the feeder lids are raised at the same time. A scent roller is also positioned adjacent to the trap floor and is connected to the trigger mechanism by a linkage that causes the trigger mechanism to be tripped when the scent roller is lifted.

An axle cartridge member receives a pair of torsion stub axles at opposite lateral sides thereof. The torsion stub axles include elongated axle housings, which are sandwiched between two parallel plates to align the torsion stub axles with respect to one another. The cartridge member includes a central arch extending between the two torsion stub axles, which can provide additional ground clearance when the axle cartridge member is mounted to a trailer.

A utility trailer has a body from with a front end and a rear end. A hitch is connected to the front end of the body frame. A wheel axle is connected to the body frame and has a pair of wheels that extend below the body frame. A first load support and a second load support are provided and positioned on the body frame in parallel spaced relation to each other. The second load support is spaced from the first load support such that the second load support is positioned closer to the front end of the body frame than the first load support.

In some embodiments, a powered trailer is provided having a chassis, a fixation structure for fixing the chassis to a target vehicle to be pushed, a drive mechanism for applying motive force to the chassis, an energy source for powering the drive mechanism, and a controller for controlling the application of motive force to the chassis by the drive mechanism. The drive mechanism is actuated by the controller to push the target vehicle.

A firebox having upper and lower manifolds with a double wall structure extending between the manifolds and providing fluid communication between the manifolds and cooling to the walls. The upper manifold has blades directing a curtain of air over and down into an interior box defined by an enclosing interior wall of the double wall structure.

In some implementations, a utility cart includes (a) a cargo hold having a cargo bed; (b) an assembly having a wheel arm having a first catch, a handle arm having a second catch, and a wheel; the wheel arm and handle arm coupled together at an angle and adjacent a pivot point; the wheel rotatably coupled to a distal end of the wheel arm; (c) a locking mechanism and a spring member, the locking mechanism having a first locking pin and a second locking pin; and (d) a plurality of bearing wheels disposed below a bottom surface of the cargo bed.

A trailer has a three-section flat bed in which the front and rear sections fold onto the middle section. The trailer has an airbag suspension system and one wheel on each side. When the airbags are deflated, the entire flat bed forms a ramp for loading and unloading. When the airbags are deflated and the flat bed is folded, the trailer can be stored vertically while resting on its wheels.

A bi-fold trailer system includes a trailer-chassis, at least two wheel assemblies rotatably coupled to said trailer-chassis, and a plurality of casters coupled to the trailer-chassis. The trailer-chassis includes a frame, an extension, and a yoke. The yoke is removably coupleable to the extension of the trailer-chassis. The bi-fold trailer system is removably coupleable to a vehicle. The frame of the trailer-chassis includes a left-side-frame and a right-side-frame, with the left-side-frame and the right-side-frame hingedly coupled such that the left-side-frame and the right-side-frame are rotatable outward from each other into an open position when removed from the vehicle.
