Dock Plate
A dock plate is form of portable bridge used to both span the gap and adjust for elevation differences between a truck bed and a loading dock or warehouse floor. Other devices used to achieve the same ends include dock boards, and electric and pneumatic dock levelers and lifts. These various devices differ in construction, suitability to dock conditions, cost of installation, and loading capacity. Dock plates and dock boards are generally portable; dock levelers and lifts are generally permanent fixtures. Dock plates and dock boards are simply metal ramps which bridge the gaps between dock and truck. Dock plates are generally made out of aluminium whilst dock boards are generally made out of steel for greater strength. Aluminium dock plates are more suitable for lighter loads, including the weight of handcarts and dollies, whereas steel dock boards are used for heavier motorized equipment such as fork lift trucks and electric pallet jacks. Another difference is that dock p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truck
A truck or lorry is a motor vehicle designed to transport freight, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a " tractor". The majority of trucks currently in use are powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in North America. Electrically powered trucks are more popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loading Dock
A loading dock or loading bay is an area of a building where goods vehicles (usually road or rail) are loaded and unloaded. They are commonly found on commercial and industrial buildings, and warehouses in particular. Loading docks may be exterior, flush with the building envelope, or fully enclosed. They are part of a facility's service or utility infrastructure, typically providing direct access to staging areas, storage rooms, and freight elevators. Basics In order to facilitate material handling, loading docks may be equipped with the following: * Bumpers – protect the dock from truck damage, may also be used as a guide by the truck driver when backing up. * Dock leveler – a height-adjustable platform used as a dock plate, bridge between dock and truck, can be operated via mechanical (Spring (device), spring), Hydraulics, hydraulic, or Pneumatics, air powered systems. * Dock lift – serves the same function as a leveler, but operates similar to a Aerial work platform#Sc ...

Warehouse
A warehouse is a building for storing goods. Warehouses are used by manufacturers, importers, exporters, wholesalers, transport businesses, customs, etc. They are usually large plain buildings in industrial parks on the rural–urban fringe, outskirts of cities, towns, or villages. Warehouses usually have loading docks to load and unload goods from trucks. Sometimes warehouses are designed for the loading and unloading of goods directly from railways, airports, or seaports. They often have crane (machine), cranes and Forklift truck, forklifts for moving goods, which are usually placed on International Organization for Standardization, ISO standard pallets and then loaded into pallet racking, pallet racks. Stored goods can include any raw materials, packing materials, spare parts, components, or finished goods associated with agriculture, manufacturing, and production. In India and Hong Kong, a warehouse may be referred to as a godown. There are also godowns in the Shanghai Bund. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevator
An elevator (American English) or lift (Commonwealth English) is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack. Elevators are used in agriculture and manufacturing to lift materials. There are various types, like chain and bucket elevators, grain augers, and hay elevators. Modern buildings often have elevators to ensure accessibility, especially where ramps aren't feasible. High-speed elevators are common in skyscrapers. Some elevators can even move horizontally. History Pre-industrial era The earliest known reference to an elevator is in the works of the Roman architect Vitruvius, who reported that Archimedes ( – ) built his first elevator probably in 236 BC. Sources from later periods mention elevators as cabs on a hemp rope, powered by people o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handcart
A cart or dray (Australia and New Zealand) is a vehicle designed for transport, using two wheels and normally pulled by draught animals such as horses, donkeys, mules and oxen, or even smaller animals such as goats or large dogs. A handcart is pulled or pushed by one or more people. Over time, the word "cart" has expanded to mean nearly any small conveyance, including shopping carts, golf carts, go-karts, and UTVs, without regard to number of wheels, load carried, or means of propulsion. History The history of the cart is closely tied to the history of the wheel. Carts have been mentioned in literature as far back as the second millennium B.C. The first people to use the cart may have been Mesopotamians. Handcarts pushed by humans have been used around the world. Carts were often used for judicial punishments, both to transport the condemned – a public humiliation in itself (in Ancient Rome defeated leaders were often carried in the victorious general's triumph) – ...

Hand Truck
A hand truck, also known as a hand trolley, dolly, stack truck, trundler, box cart, sack barrow, cart, sack truck, two wheeler, or bag barrow, is an L-shaped box-moving cart, handcart with handles at one end, wheels at the base, with a small ledge to set objects on, flat against the floor when the hand truck is upright. The objects to be moved are tilted forward, the ledge is inserted underneath them, and the objects allowed to tilt back and rest on the ledge. The truck and objects are then tilted backward until the weight is balanced over the wheels, making otherwise bulky and heavy objects easier to move. It is a lever#Classes of levers, first-class lever. Overview Sack trucks were originally used in the 18th century to move large sacks of spices on docks child labour, by young boys, who were unable to lift the large sacks by hand. By using this method they were able to work as well as grown men in moving items around. Later, such trucks were amended for use in many different ...

Fork Lift Truck
A forklift (also called industrial truck, lift truck, jitney, hi-lo, fork truck, fork hoist, and forklift truck) is a powered industrial truck used to lift and move materials over short distances. The forklift was developed in the early 20th century by various companies, including Clark, which made transmissions, and Yale & Towne Manufacturing, which made hoists. Since World War II, the development and use of the forklift truck has greatly expanded worldwide. Forklifts have become an indispensable piece of equipment in manufacturing and warehousing. In 2013, the top 20 manufacturers worldwide posted sales of $30.4 billion, with 944,405 machines sold. History Developments from the middle of the 19th century to the early 20th century led to today's modern forklifts. The forerunners of the modern forklift were manually powered hoists to lift loads. In 1906, the Pennsylvania Railroad introduced battery-powered platform trucks for moving luggage at their Altoona, Pennsylvani ...

Pallet Jack
A pallet jack, also known as a pallet truck or pallet pump, is a tool used to lift and move pallets. Pallet jacks are the most basic form of a forklift and are intended to move palletized loads within warehouses, distribution centers, retail stores, and construction sites. Operational principle The jack is steered by a tiller-like lever called a 'tow bar' that also acts on the pump piston for raising the forks. A small lever on the tow bar's steering handle releases the hydraulic fluid, causing the forks to lower. The steering wheels are located directly below the tow bar and support the jacking mechanism. The front wheels inside the end of the forks are mounted on push rods attached to linkages that go to levers attached to the jack cylinder. As the hydraulic jack at the 'tiller' end is raised, the links force the wheels down, raising the forks vertically above the front wheels, raising the load upward until it clears the floor. The pallet is only lifted enough to clear the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Pallet Jack
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...
