pulleys and trolleys and other simple machinery

In everyday life are often used some simple small and light material handling machinery, such as various trolleys. Man's first move by hand, carrying, labors to keep material, then gradually use animal power, and created a lever, pulley, pulleys and trolleys and other simple machinery.
Modern material handling machinery began in the nineteenth century. Before and after the 1830s, there has been steam-driven lifting machinery and conveyors; late nineteenth century, the internal combustion engine applications, material handling machinery access to rapid development; 1917, there has been handling both lifting can forklift appear seventies computer control system, material handling machinery, material handling into the highly automated session.
Material handling machinery according to the functions can be divided into lifting machinery, conveyors, handling machinery, truck, forklift trucks and warehouse equipment such as five. In general, the forklift jacks machinery for lifting and handling, but the transport distance is short, it's institutions intermittent movement; conveyors for continuous transportation of materials, transportation routes usually fixed, mostly used to transport bulk materials; handling mechanical energy self-extract and unloading materials. Transport vehicles can be flexibly arranged transportation routes, economic transport distance is longer, for indoor or outdoor work, with driving wheel; storage equipment in the warehouse is completed pile, extraction, storage of materials, comprising silos, overhead storage and to feeding machines. With industrial development, many mechanical and uses a variety of functions, such as forklifts are handling vehicles, used to handling, but also lifting heavy loads.
Material handling machinery for the production of the service, its design and selection process should be subject to the needs of the production, but also created a new material handling machinery often leads to the production process changes and improvements. For example, bucket wheel stacker reclaimer machine there, and formed a bucket wheel stacker reclaimer for the heart, vascular belt, computer automation for the nerve center of a large field of bulk materials handling systems, thus changing the port, mines and thermal power plants and other bulk materials yard layout; instead of overhead crane with a forklift handling operations conducted workshops, plant structure can simplify and reduce the costs of infrastructure.
