A caster adapter is used for adapting a plurality of caster wheels onto a hand truck of the type having a backing frame extending longitudinally between a handle portion at a top end and a toe plate at a bottom end. The adapter includes a frame assembly mounting the caster wheel assemblies thereon for rolling movement along a ground surface. A pair of pivot couplings on the frame assembly pivotally couple the frame assembly on the backing frame of the hand truck for pivotal movement about a tilt axis which is parallel to the toe plate and proximate to the bottom end of the backing frame.

A hand truck includes a quick release/attach mechanism operating according to a method for quickly and easily exchanging various tools with the hand truck, the quick release/latch mechanism including biased locking pins movably located within tubular frame members integral to the hand truck and proximal holes in the tubular frame members for receiving a projection member of the tool and spaced a predetermined distance from a hangar portion of the tool and wherein the hangar portion may be hung on a crossbar of the tubular frame and then the projection members of the tool may be coupled with and retained by the locking pins of the tubular frame. The arrangement requires no hand tools such as wrenches or screwdrivers, and no external fasteners such as pins or bolts. The geometry of the cross bars on the hand truck allow tool attachments to be captured or releases simply by tilting the hand truck forward or backward. The tool attachments are then locked to the truck by means of locking rods and pins that operate inside the two main tubes of the hand truck.

A cart includes a first frame having two side tubes and each of the two side tubes has a first wheel connected thereto. A second frame is pivotably connected to the first frame and has a transverse tube. Two second wheels are connected to the transverse tube. A locking device is slidably connected to the first frame so as to be positioned at a first position or a second position. When the locking device is set at the first position, the second frame is pivoted to a position substantially parallel to the first frame, and the first wheels support the cart. When the locking device is set at the second position, the second frame is pivoted to a position substantially perpendicular to the first frame. The first and second wheels support the cart.

A hand truck is provided, comprising a frame, a pair of back wheels secured to a first edge of the frame, a nose plate hingedly secured to the first edge of the frame, a telescopic handle hingedly secured to a second edge of the frame opposite the first edge, and a motorized wheel assembly separately connected to the second edge of the frame and to the handle. The hand truck has three configurations: a hand truck configuration whereby the nose plate is in a horizontal position, the frame is in a vertical position, and the handle is extended vertically; a storage configuration whereby the nose plate is in a vertical position, the frame is in a vertical position, and the handle is retracted; and a scooter configuration whereby the nose plate is in a horizontal position, the frame is in a horizontal position, and the handle is extended.

A two-wheeled cart is especially adapted for use as a game cart and may be easily towed by a conventional mountain bike. The cart has two interchangeable wheel positions. In the first wheel position the wheels are attached to the frame at opposite lateral sides of the cart and in this position the center of mass of a load carried on the bed of the cart is relatively low. In the second wheel position the wheels are aligned one in front of the other along the direction of travel as the cart is moved; in this position, the bed of the cart is raised to a relatively higher position than the position of the bed when the wheels are in the first wheel position so the center of mass of a load carried on the bed is relatively higher than when the wheels are in the first wheel position.

a foldable stroller capable of being formed into a trolley, comprising a front tube, a rear tube, a seat frame, an armrest, a pushing lever, and a handle connected to the pushing lever via a second joint assembly which allows pivotal movement of the handle relative to the pushing lever; the front tube having an extensible draw bar; wherein when the rear tube, seat frame, armrest and pushing lever are folded toward the front tube by joints, the handle is pivotally moved at 90-100 degrees relative to the pushing lever through the second joint assembly, and then the draw bar is pulled out of the front tube, whereby the trolley is formed; the foldable stroller can be folded in a small size and is easy to carry and store, moreover, if the baby has grown up, the stroller can be used as the trolley to avoid unnecessary waste.

A hand truck with main wheels and a toe plate also includes a handle assembly that is mounted to the frame of the hand truck so that the handle assembly is able to rotate and slide relative to the truck frame. The hand truck may be arranged in a first upright dolly position in which the handle assembly is generally aligned with the truck frame and a second cart position in which the truck frame is generally horizontal and the handle assembly is extended and rotated so that it is upright and normal relative to the truck frame. A latch assembly mounted to the truck frame is able to releasably receive and secure the handle assembly in the first upright dolly position.

A pallet is provided for supporting cylinders. The pallet can have a convex spine extending substantially the length of the pallet in a longitudinal direction, having a backstop at a first end. The pallet has two trays attached transverse to the convex spine, each tray having longitudinal fluted indents to restrain a cylinder from rolling transverse, the longitudinal fluted indents are each arranged to accept a cylinder from above. The pallet has a left outrigger attached and extending transverse to the convex spine, the left outrigger stabilizing the pallet with respect to terrain, as well as a right outrigger attached and extending transverse to the convex spine, the right outrigger stabilizing the pallet with respect to terrain. The pallet can have a coupling extending from an end of the convex spine, wherein the coupling is arranged to take a crane hook in engagement to pull the pallet.

A braking apparatus for a hand truck that keeps the hand truck stable while lifting or dropping a load from the hand truck. The braking apparatus includes a lever and clamps for pivotally mounting the lever to an axle of the hand truck, and a recoiling mechanism that allows the lever to switch between a deployed position and a non-interfering position. The operator can press the lever against the floor to prevent the rolling of the hand truck while loading.
