The present invention provides a pallet carrier, comprising a carrier frame structure; a fork structure disposed on the carrier frame structure; a driving wheel structure comprising driving wheels that are articulated to the carrier frame structure, wherein each one of the driving wheels is set as a one-piece wheel structure integrated with a driving motor and a hub. The pallet carrier has the advantages of simple structure and work reliability.

An apparatus for removing and/or installing a side guide of a trailer-mounted boat capture system for guiding a boat onto the trailer, the apparatus comprising: an outboard post pivotally attached to an upper support rail of the side guide; two inboard posts, each pivotally attached to the side guide proximal to where the side guide is attached to the trailer via first pins, wherein each inboard post includes a manual leveling jack; an attachment point on the side guide suitable for attaching a winch cable from a boat held in the boat capture system; and second pins attaching the side guide to the trailer such that when the first pins are removed the side guide is free to pivot around the second pins from an upright position towards a support surface.

An unmanned underwater vehicle (UUV) transport cart comprising: a wheeled frame including vertical posts, a front end, and a rear end; a UUV cradle adjustably clamped to the vertical posts such that the UUV cradle is vertically adjustable with respect to the frame; a U-shaped handle pivotally attached to the front end of the frame such that the U-shaped handle pivots up and down around a first axis, wherein the U-shaped handle includes a handle spring that acts between the U-shaped handle and the frame so as to bias the U-shaped handle toward an upward orientation; side handles pivotally attached to the UUV cradle such that the side handles pivot up and down around side axes that are perpendicular to the first axis; and a hand brake affixed to the U-shaped handle and configured to provide active brake control of the wheeled frame.

A hand truck having improvements made to simplify and make more ergonomically use of a hand truck by an operator. The hand truck provided having adjustable handles and a bottom portion having adjustable stair climbers with improved feature and an improved wheel and brake assembly have an axle-less wheel assembly and an improved caliper mounting system. These features are discussed in detail in the forgoing.

A wheel structure that makes braking easy and prevents sudden stops, and a pushcart having the wheel structure are provided. The wheel structure includes a rotor that is rotatable about an axle and is stopped from rotating by a brake member, a wheel that is coaxial with the rotor and is rotatable about the rotor, and a relative-rotation resisting member that is disposed between the rotor and wheel and produces resistance force resisting the relative rotation of the rotor and wheel.

A cart assembly that is designed to hold and transport one or more ball hoppers. The ball hoppers have baskets that are supported by legs. The baskets are configured to hold some type of ball, such as a tennis ball or a golf ball. The cart assembly can transport the ball hoppers as they are standing on legs. The cart assembly has a platform that is supported by wheels. The wheels provide the platform with the ability to roll. Receptacles are present on the platform. The receptacles are sized, shaped and positioned to receive the legs of a ball hopper when the ball hopper is placed on the platform. Once a ball hopper is attached to the platform, the ball hopper becomes part of the cart assembly and can roll with the cart assembly from point to point.

An electric handcart, comprising: a main body (1), a power supply device (9) mounted on the main body (1), a power device, and a control device. The power supply device (9) and the control device are separately connected to the power device.

A snap-hook comprising: a hook-shaped body having a throat opening and a shank end, wherein the hook-shaped body includes a primary aperture located at the shank end suitable for attaching a primary line and a secondary aperture located approximately opposite the throat opening suitable for attaching a secondary line; and a dual-direction latch pivotally attached to the hook-shaped body such that the dual-direction latch spans the throat opening when in a neutral position and is capable of pivoting into and out of the throat of the hook-shaped body, wherein the dual-direction latch comprises a bent wire having two free ends, each end inserted in a different hole of two holes in the hook-shaped body that are non-axially-aligned resulting in a spring force that biases the dual-direction latch toward the neutral position and resists pivotal movement of the dual-direction latch both into and out of the throat.

An accessory plate accommodates a caliper brake disc system in either a retrofit kit or in the original construction of wheelbarrows, hand carts and other wheeled, slow speed vehicles. The accessory plate or extension plate is secured to an axle or hub providing attachment to a caliper system. The accessory plate may be modified to accept other accessories, including but not limited to electric motors, drum brake arms and accessories, lights, battery packs or other accessories pertinent to the vehicle's enhanced operation. A hub system may be optionally used and may help to accommodate the installation of an accessory plate and/or rotor disc and/or drum brake or drum brake actuator.

A weight-bearing device includes a single wheel, a frame attached to the wheel, and an electric motor attached to the frame. The electric motor is configured to rotate a first gear, connected to a second gear with a chain. The second gear is connected to the wheel. The second gear and the first gear may have a gear ratio of greater than 8:1.
