The present invention is a stably balanced wheelbarrow which is easy to use in different ground conditions like un-even terrain or obstacles like stones. Wheelbarrow includes a main frame, a carriage, a wheel and a wheel securing unit. Main frame supports carriage, wheel and wheel securing unit. Carriage can be of any desired shape and holds load/objects. Wheel is made wide enough to provide support to wheelbarrow such that wheelbarrow is stable. Wheel is secured by wheel securing unit. Wheel securing unit includes a pair of flange bearings and spacers. Flange bearings are disposed on either side of wheel and provide frictionless rotation of wheels. Spacers are provided on either side between flange bearings and frame for preventing movement of wheel on axle.

A material handling device is provided. The material handling device includes a bottom, a frame, a wall, an a plurality of wheels. The bottom includes an upper surface and a lower surface. The frame includes an upper surface and a lower surface. The wall surrounds the bottom and the frame, and includes an inner surface, an outer surface and an inner shelf attached to a lower portion of the inner surface. The inner surface includes an upper surface attached to a portion of the lower surface of the bottom, and a lower surface attached to a portion of the upper surface of the frame. Each wheel is attached to the lower surface of the frame.

A hand-driven, wheeled carrier deceleration device, applied to an axle of a hand-driven, wheeled carrier, is introduced and has a wheel, driven gear, reluctance motor and resistive component. The wheel, pivotally disposed at the axle, has a drive gear which rotates together with the wheel. The driven gear, disposed beside the axle, meshing with and driven by the drive gear, has a connection portion. The reluctance motor, connected to the connection portion and driven by the driven gear, has permanent magnets and metal elements. The metal elements and permanent magnets are arranged annularly. The metal elements rotate relative to the permanent magnets. The resistive component electrically connects to the permanent magnets. Therefore, a driving force exerted on the hand-driven, wheeled carrier is partially offset by reluctance to effectively slow down the hand-driven, wheeled carrier.

A pallet moving system includes a pallet dolly puller, and a pallet dolly with a guiding structure thereon permitting and facilitating the blind engagement and disengagement of the dolly puller to the pallet. The dolly puller includes caster wheels, a handle, and at least one projecting portion configured to mateably couple with recessed portions on the underside of the pallet dolly in order that the pallet dolly may be moved and readily re-positioned even in confined spaces.

A shopping cart foot wheel capable of warning the abrasion status of the braking block comprising an escalator wheel assembly; the escalator wheel assembly comprises an escalator wheel core and escalator wheel discs; the escalator wheel discs are located on the two sides of the escalator wheel core, and are coaxially arranged with the escalator wheel core; the escalator wheel assembly further comprises an escalator wheel support, wherein the escalator wheel support is provided with an escalator wheel axle; locking nuts are simultaneously arranged at the two ends of the escalator wheel axle; the escalator wheel core is connected with the escalator wheel axle in a sleeved mode.

A dolly for transporting products thereon, the dolly comprising a top with a product support surface and an opposing underside, a plurality of casters provided on the underside, two of the casters being swivel casters configured to rotate relative to the product support surface; biasing means configured to bias a wheel of each swivel caster towards a first equilibrium position. A plurality of reinforcing ribs provided on the underside; wherein at least one of the reinforcing ribs is a curved reinforcing rib, and; the at least one curved reinforcing rib extends from a first caster mounting area to a second caster mounting area. Further including, a dolly carrier pallet comprising a pallet provided with a dolly receiving layer, wherein the dolly receiving layer is provided with generally rectangular wheel receiving recesses for receiving swivel casters and is provided with generally rectangular wheel receiving recesses for receiving fixed casters.

The present invention relates to a running gear having a carrier plate and a first roller, a second roller and a third roller, which are arranged on the carrier plate. Simplified handling and/or increased stability of the running gear is produced if the first roller can rotate about a first rolling axis running parallel to a plane of extent of the carrier plate and the second roller can rotate about a second rolling axis running parallel to the plane of extent and the third roller can rotate about a third rolling axis running parallel to the plane of extent. The invention further relates to an arrangement having at least two such running gears, wherein at least two such running gears are connected to each other.

Exemplary embodiments are directed to pool cleaners that remove debris from water using a plurality of cyclonic flows, or that include a removable impeller subassembly, a check valve for a debris canister, a particle separator assembly having a handle that locks to the pool cleaner, a modular roller drive gear box, or a roller latch that secures a roller to the pool cleaner. Exemplary embodiments are also directed to the check valve and the roller latch themselves. Exemplary embodiments are directed to a filter medium for pool cleaners that includes embossments providing flow channels for water, and to roller assemblies for pool cleaners. Exemplary embodiments are directed to pool cleaners including alternative pump motor engagements. Exemplary embodiments are directed to pool cleaners power supplies that include a potted and contoured power board assembly, and to kickstands therefor. Exemplary embodiments are directed to a pool cleaner caddy, and removable wheels therefor.

A utility handcart for transporting equipment, materials, goods, supplies, animals, and people during or after a natural or man made disaster. The handcart includes a solid body and integrated body/frame design increasing durability to withstand constant use over long distances on rough terrain. An ergonomic placement of side-rails, adjustable height, and low rolling resistance through use of modern no-flat wheels with precision bearings, eases burdens and energy demands which are placed on humans when transporting various items. Materials are selected to reduce or eliminate regular service or maintenance. A kickstand aids the loading and unloading of the handcart, and positions the handcart ready for use. A ratcheting uphill assist prevents rolling backwards. The handcart may be assembled or disassembled without tools and components compactly arranged for storing and transporting.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.
